Abstract
Cultured meat shows great promise as a more sustainable alternative to conventional meat consumption. However, consumer acceptance of cultured meat remains a great challenge as studies indicate a general reluctance to adopt this product. Notably, while existing literature has provided various factors influencing consumer acceptance of cultured meat, there is a limited focus on the use of affective cues. The present research examines the impact of regret appeal on consumers' willingness to try cultured meat. In two experimental studies, the authors investigate (1) the interactive effect between regret and age on willingness to try cultured meat, and (2) the role of loss aversion as a mediating factor between regret and willingness to try cultured meat. The results demonstrate the effectiveness of regret appeal in increasing consumers' willingness to try cultured meat, particularly among older populations. This is because older populations exhibit higher levels of loss aversion. The present study is the first to shed light on the interactive effect of regret and age in influencing sustainable product acceptance. Furthermore, the study establishes the first empirical evidence to demonstrate that loss aversion is a valid self-regulating strategy adopted to cope with the feeling of regret in a consumption context.

Appetite 2024; 200:107501. [PMID: 38763298 DOI: 10.1016/j.appet.2024.107501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Revised: 05/10/2024] [Accepted: 05/15/2024] [Indexed: 05/21/2024]
Abstract
This study investigates the structure of factors that influence consumer intentions to both try and to consume cultured proteins, and their intentions to substitute vegan, vegetarian and omnivore diets with these alternative protein sources. Comprehensive survey data (N = 3862) was collected from three Nordic countries (Denmark, Finland, and Norway) and analysed using confirmatory factor analysis and structural equation modelling. Theoretically, this article draws from behavioural models of environmental psychology, identity theory, and attitude theory. Results indicate that beliefs about the necessity of an industry producing cultured proteins and impacts of cultured proteins on the global economy are significant predictors of consumer intentions. Moreover, participants who exhibited high levels of general and food innovativeness were more likely to express positive intentions to consume cultured proteins. Social norms influenced consumer intentions: Individuals surrounded by positive attitudes and intentions toward cultured proteins within their social networks were more inclined to want to consume these products. The predictor variables in the final model accounted for between 39% and 66% of the variance in the different cultured proteins related intentions. Understanding consumer intentions better can inform targeted communication strategies aimed at promoting the advantages of cultured proteins and facilitating its adoption.

Mulberry (Morus alba L.) leaf powder modified the processing of meat alternatives: Principal component analysis from apparent properties to chemical bonds. Food Chem 2024; 450:139318. [PMID: 38613965 DOI: 10.1016/j.foodchem.2024.139318] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 03/23/2024] [Accepted: 04/08/2024] [Indexed: 04/15/2024]
Abstract
For texture control in plant-meat alternatives, the interrelationship between apparent characteristics and chemical bonds in high-fiber formulations remains unclear. The influence of mulberry leaf powder on apparent characteristics and chemical bonds of raw materials, block and strip products at addition amounts of 0.5-25% was analyzed. The results showed that 8% addition significantly increased the chewiness of the block by 98.12%. The strips' texture shows a downward trend, and the processing produced more redness and color difference. Additives promoted the formation of voids, lamellar and filamentous structures, and the strip produced more striped structures. Disulfide bonds significantly increased in the block, and the β-turn in the secondary structure enhanced by 12.20%. The β-turn transformed into a β-sheet in strips. Principal component analysis revealed that the texture improvement was associated with producing disulfide bonds and β-turn, providing a basis for high-fiber components to improve products' apparent characteristics by chemical bonds.

Abstract
Slovenia, influenced by Slavic, Mediterranean, and Balkan cultures, along with Austro-Hungarian traditions and strong environmental concerns, is an ideal case study for understanding consumer perceptions of edible insects and increasing their acceptance as an alternative protein source. A survey conducted in Slovenian and English with 537 participants examined existing perceptions and acceptance of edible insects as food and livestock feed. Findings show moderate interest in insects, particularly in non-visible, integrated forms, despite most participants not having tried whole insects. Young, educated individuals and those residing in rural areas have tried insects more often than other sociodemographic groups. Men showed more interest in entomophagy compared to women. Crickets, grasshoppers, and locusts were most acceptable, while cockroaches were least favored. Economic factors are crucial, with a preference for insect-based products priced similarly to conventional foods. The majority also support using insects as livestock feed. These results can aid policymakers at regional and national levels, help businesses market these products, and contribute to the literature on consumer responses in different European regions regarding edible insects as a sustainable food source.

Abstract
Global demand for food is expected to nearly double by 2050. Alternative proteins (AP) have been proposed as a sustainable solution to provide food security as natural resources become more depleted. However, the growth and consumer intake of AP remains limited. This review aims to better understand the challenges and environmental impacts of four main AP categories: plant-based, insect-based, microbe-derived, and cultured meat and seafood. The environmental benefits of plant-based and insect-based proteins have been documented but the impacts of microbe-derived proteins and cultured meat have not been fully assessed. The development of alternative products with nutritional and sensory profiles similar to their conventional counterparts remains highly challenging. Furthermore, incomplete safety assessments and a lack of clear regulatory guidelines confuse the food industry and hamper progress. Much still needs to be done to fully support AP utilization within the context of supporting the drive to make the global food system sustainable.

The Impact of Freeze-Dried Tenebrio molitor Larvae on the Quality, Safety Parameters, and Sensory Acceptability of Wheat Bread. INSECTS 2024; 15:603. [PMID: 39194808 DOI: 10.3390/insects15080603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/24/2024] [Revised: 08/03/2024] [Accepted: 08/08/2024] [Indexed: 08/29/2024]
Abstract
The research context involves analyzing the potential benefits derived from integrating insect protein into everyday food items. Utilizing methods consistent with established food science protocols, wheat bread was prepared with variations of 0%, 5%, 10%, and 15% Tenebrio molitor larvae powder, derived from larvae cultivated on brewery spent grain. A substrate selected for its superior nutritional content and a substrate with agar-agar gels were used. The tests included basic bread tests; sugar, acrylamide, amino, and fatty acid (FA) tests; and sensory acceptability. The results have shown that the acrylamide levels in bread with larvae remained below harmful thresholds, suggesting that using T. molitor can be a safe alternative protein source. The incorporation of powdered T. molitor larvae (p-TMLs) into bread was observed to increase certain sugar levels, such as glucose, particularly at higher larval concentrations. The addition of T. molitor significantly raised the protein and fat levels in bread. The inclusion of larvae enriched the bread with essential amino acids, enhancing the nutritional value of the bread significantly. The FA profile of the bread was altered by the inclusion of p-TMLs, increasing the levels of monounsaturated FAs. Despite the nutritional benefits, higher concentrations of larvae decreased the sensory acceptability of the bread. This suggests that there is a balance to be found between enhancing the nutritional content and maintaining consumer appeal. These findings highlight the potential for using p-TMLs as a sustainable, nutritious ingredient in bread making, although the sensory qualities at higher concentrations might limit consumer acceptance.

Abstract
Emotions are present in almost everything we do, including meat procurement, preparation and consumption. This paper examines the main drivers of this consumption, including sensory and hedonic properties, physiological needs, historical reasons and habits, social influence, ethical motives, practical aspects and other determinants, exploring the meat-related emotions as both an outcome of consumption and as consumption drivers. Emotions are affected by multiple factors relating to the context, the information provided, and the type of product. Positive emotions such as pleasure, satisfaction, proudness and joyfulness have been described in relation to meat, as well as some neutral or negative ones. To enhance positive emotions and increase meat liking, it is essential to improve animal welfare and promote a more sustainable production, focusing on nutritional and sensory quality and providing consumers with reliable information.

Abstract
The promotion of meat substitutes to reduce meat intake is a promising way to reduce the environmental and public health externalities of meat consumption while preserving the important role of taste and texture in meat products. However, the market for meat substitutes is developing more slowly than expected. Therefore, we analyze the factors associated with the heterogeneity in meat substitute consumption in Germany, a country where meat traditionally plays an important role. We use revealed preference data on meat substitute sales from 1025 individual retailers, sociodemographic data, and election results from 92 regions in Germany over the period 2017-2021, to analyze whether differences in meat substitute consumption are associated with consumers' political orientation (liberal/left or conservative/right) and socio-demographic variables. We also investigate whether election results for parties with stronger climate protection goals are associated with meat substitute consumption. Our results show that meat substitute consumption varies significantly across Germany and that this is related to differences in socio-demographic characteristics and voting behavior across regions. Voting for the Green Party and parties with strong climate protection ambitions is positively related to the market share of meat substitutes. In contrast, voting for Germany's most conservative party, which has the lowest ambitions in terms of climate protection targets, is associated with lower meat substitute consumption. Therefore, manufacturers could develop tailored marketing strategies that specifically target these voter groups in order to increase the market share of meat substitutes as alternatives to meat products.

Abstract
Cultured meat is a promising substitute for regular meat, but its introduction faces challenges and expected consumer resistance. While some studies investigate how communication strategies and advertising appeals can address these concerns, the role of social media influencers in promoting cultured meat adoption remains yet to be explored. Across two online experimental studies involving 752 participants recruited from Prolific, this research investigates how influencer type (micro- vs. mega-influencer) affects consumers' willingness to buy cultured meat. Study 1 reveals that consumers are more willing to buy cultured meat when it is endorsed by micro- rather than mega-influencers. Further, perceived endorsement authenticity mediates this effect such that micro-influencers endorsements are perceived as more authentic than those of mega-influencers. Study 2 demonstrates that these effects are moderated by influencer expertise and type of meat, where micro-influencers with health (but not fashion) expertise have a more pronounced impact on increasing willingness to purchase cultured meat (but not regular meat). This research provides theoretical insights into how consumers perceive influencer endorsements for cultured meat. These findings aim to enhance consumer acceptance of cultured meat while offering actionable guidance for practitioners on promoting cultured meat brands on social media.

Abstract
This article is concerned with the dynamics of change in protein consumption practices from the perspective of the consumer. It is based on a model, informed by social representation theory, that aims to understand the role played by various types of representation of alternative proteins in the process of changing food consumption practices. It discusses the reception, by consumers, of the representations associated with alternative proteins on Instagram. Methodologically, three focus groups were organized with different consumer segments (omnivorous, flexitarian and vegetarian and vegan consumers), as well as seven individual interviews. Participants were submitted to the social representations of alternative proteins, and visual stimuli from social media were mobilized for this purpose. Results show that the publications which boast the environmental, animal welfare or health attributes of alternative proteins generally contribute to the cultivation of new elements of practices. While this kind of publications is essential to help consumers question their established practices linked to meat and dairy consumption, they can also generate a critical reception that is not conducive to change, making them a double-edge sword. Publications that relate to the representations involved in daily food consumption proteins (e.g. that alternative proteins are versatile and crowd-pleasing) emerge as being safer in terms of reception, although as standalone they may not be able to achieve a deep level of change in food consumption practices. The results of this study show the importance of deploying a diverse communication strategy about alternative proteins that appeal to a variety of consumer segments.

Abstract
Plant-based proteins offer sustainable and nutritious alternatives to animal proteins with their techno-functional attributes influencing product quality and designer food development. Due to the inherent complexities of plant proteins, proper extraction and modifications are vital for their effective utilization. This review highlights the emerging sources of plant-based proteins, and the recent statistics of the techniques employed for pretreatment, extraction, and modifications. The pretreatment, extraction and modification approach to modify plant proteins have been classified, addressed, and the recent applications of such methodologies are duly indicated. Furthermore, this study furnishes novel perspectives regarding the potential impacts of emerging technologies on the intricate dynamics of plant proteins. A thorough review of 100 articles (2018-2024) shows the researchers' keen interest in investigating novel plant proteins and how they can be used; seeds being the main source for protein extraction, followed by legumes. Use of by-products as a protein source is increasing rapidly, which is noteworthy. Protein studies still lack knowledge on protein fraction, antinutrients, and pretreatments. The use of physical methods and their combination with other techniques are increasing for effective and environmentally friendly extraction and modification of plant proteins. Several studies explore the effect of protein changes on their function and nutrition, especially with a goal of replacing ingredients with plant proteins that have improved or enhanced qualities. However, the next step is to investigate the sophisticated modification methods for deeper insights into food safety and toxicity.

Abstract
Securing a sustainable global food supply for a growing population requires a shift toward a more plant-based diet. The application of plant-based proteins is therefore increasing, but unpleasant off-flavors complicate their use. Here, we screened 97 microorganisms for their potential to remove off-flavors in a process with limiting amounts of fermentable sugar. This allowed the production of a more neutral-tasting, purified food ingredient while limiting microbial growth and the production of typical fermentation end products. We demonstrate that various lactic acid bacteria (LAB) and yeasts remove "green" aldehydes and ketones. This conversion can be carried out in less than one hour in almond, pea, potato, and oat proteins. Heterofermentative LAB was best at aldehyde and ketone neutralization with minimum de novo formation of microbial volatiles such as ethylacetate (sweet, fruity) or alpha-diketones (butter- and cheese-like). While sensory properties were improved, changes in protein solubility, emulsification, foaming, and in vitro digestibility were limited.

Abstract
The emerging field of cellular agriculture has accelerated the development of cell-cultivated adipose tissue as an additive to enhance the flavor of alternative meat products. However, there has been limited research to evaluate the sensory profile of in vitro-grown tissues compared to conventionally obtained animal fat. This study aimed to investigate the aromatic characteristics of cell-cultivated fat tissue as a flavor enhancer for meat alternatives. Porcine dedifferentiated fat (PDFAT) cells were clonally isolated and differentiated into adipocytes. This cultured adipose tissue was then analyzed alongside native porcine fat using gas chromatography-mass spectrometry (GC/MS) coupled with descriptive sensory analysis by human consumers. This evaluation enabled quantitative and qualitative assessments of volatile compounds released during cooking for both in vitro and in vivo porcine fats. The volatile profiles generated during the cooking process and fatty aroma characteristics reported by sensory consumers were largely similar between the two fat sources, with some differences in select compounds and aroma attributes. Ultimately, the consumers found comparable overall liking scores reported between the conventional and cultured porcine fats. These findings provide valuable sensory evidence supporting the viability of cell-cultivated adipose tissue as a flavor component of meat alternatives, substituting for conventional animal fat.

Abstract
The consumption of insects (entomophagy) is attracting attention for economic, environmental and health reasons. The wide range of edible insect species, rich in protein, fat, minerals, vitamins and fibre, can play an important role in addressing global food insecurity. However, consumer acceptance remains a major barrier to the adoption of insects as a food source in many countries, including Europe. The aim of this study was to determine whether health and environmental concerns, attitudes and intentions towards purchasing edible insects and foods containing edible insects are associated with willingness to consume edible insects and foods containing edible insects among young consumers (Generation Z) in Poland. An empirical study was carried out in 2023, using a questionnaire with an indirect interview method via an online platform. On the basis of surveys conducted among Generation Z in Poland, it can be concluded that health and environmental concerns determine the willingness to consume selected products containing edible insects. At the same time, it should be noted that the more positive the respondents' attitudes towards health and environmental concerns are, the greater their willingness to consume foods containing edible insects is. Attitudes and intentions towards purchasing foods containing edible insects were positively correlated with willingness to purchase and consume this type of food. The results obtained can contribute to efforts to promote the legitimacy of the production of new foods with edible insects in their composition.

Abstract
This review investigates coconut as a sustainable and nutrient-rich plant-based alternative to traditional animal-based food sources. We have explored the nutritional profile, culinary versatility, particularly focusing on the use of coconut meat, milk, cream, and oil in diverse dietary contexts when consumed in balance. Comparative analysis with animal-derived products reveals the high content of medium-chain triglycerides (MCTs), essential vitamins, and minerals in coconut, contrasted with its lower protein content. Researchers have underscored the environmental sustainability of coconut, advocating for its role in eco-friendly food production chains. We have also addressed challenges like potential allergies, nutritional balance, sensory attributes, and consumer motivations for coconut-based products, in terms of understanding the market dynamics. In conclusion, this review positions coconut as a promising candidate within sustainable diet frameworks, advocating for further research to augment its nutritional value, sensory characteristics, and product stability, thereby facilitating its integration into health-conscious and eco-centric dietary practices.

Abstract
One third of the food produced for human consumption is currently lost or wasted. Insects have a high potential for converting organic waste- and by-products into food and feed for a growing human population due to symbiosis with microorganisms. These symbioses provide an untapped reservoir of functional microbiomes that can be used to improve industrial insect production but are poorly studied in most insect species. Here we review the most current understanding and challenges of valorizing organic waste- and by-products through insects and their microbiomes for food and feed, and emerging novel food technologies that can be used to investigate and manipulate host(insects)-microbiome interactions. We further construct a holistic framework, by integration of novel food technologies including holo-omics, genome editing, breeding, phage therapy, and administration of prebiotics and probiotics to investigate and manipulate host(insects)-microbiome interactions, and solutions for achieving stakeholder acceptance of novel food technologies for a sustainable food production.

Appetite 2024; 198:107369.

Abstract
Improving health and sustainability outcomes in WEIRD (Western, Educated, Industrial, Rich, Democratic) nations necessitates a reduction in red meat consumption. Seafood is often overlooked in achieving this goal. However, simply consuming more of familiar fish species places high stress on production of these species. For this reason, diversification of seafood consumption is also critical. Here the motives for seafood consumption (frequency and diversity) are investigated across two studies by adapting the 4Ns survey to the seafood category. This 16-item survey measures four factors underpinning meat consumption: namely that it is 'Natural', 'Necessary', 'Normal' and 'Nice'. Swedish consumers' hedonic and sensory expectations of two herring concepts (traditional pickled contra novel minced and presented as a burger) are also evaluated in relation to the 4Ns. Study 1 (N = 304) revealed that the seafood 4Ns scale had a similar underlying structure to that of meat and had good test-retest reliability. Study 2 (N = 514) showed that consumers expected to like the pickled herring (associated with being 'seasoned', 'salty', 'sweet', 'firm', 'juicy', 'chewy', and 'slimy') more than the minced herring (associated with being 'mushy', 'fishy', 'grainy', 'dry' and having 'small bones'), and that 'Nice' scores affected expectations of both herring concepts. Food neophobia correlated inversely with seafood consumption frequency, expected liking, the 'Nice' subscale, and food agency. Critically, in both studies, enjoyment of seafood (higher 'Nice' scores) predicted more frequent and diverse seafood consumption, whilst agreeing that seafood is 'Necessary' for health predicted only consumption frequency, not diversity. Communicating the positive sensory attributes of seafood and developing novel product concepts in ways that disconfirm sceptical consumers' negative sensory expectations may increase acceptance of both familiar and unfamiliar seafood concepts.

Abstract
Plant-based meat alternatives (PBMAs) are increasingly popular and may contribute towards reduction of negative environmental impacts associated with the meat industry. Inferior sensory characteristics of PBMAs, compared to conventional meat products, remain a barrier for uptake of these products. This study aimed to profile a wide range of PBMAs for perceived similarity to meat, consumer liking, emotional response and sensory experience, and to determine consumer drivers of liking for this product category. Twenty-one PBMAs, spanning a broad range of product types (burger patties, sausages, meatball alternatives, chicken/beef pieces, bacon alternative, turkey roast alternative) and main protein ingredients (extruded plant proteins, tofu, or legumes/vegetables) representative of PBMAs available to Aotearoa New Zealand consumers, were tasted and evaluated by 140 Aotearoa New Zealand residents. Samples ranged widely in their perceived similarity to meat (median value range: 1.0-4.0 on a 5-point-scale) and overall liking ratings (mean ± SD, range: 35.1 ± 1.2--77.7 ± 17.4 on a 100-point hedonic scale). Overall liking ratings were driven mostly by liking for flavour, followed by texture, and less so by appearance. Sensorially, sample differentiation was mostly associated with variation in meat-related flavours and textures, or vegetable-related attributes. Notably meat flavour was the main driver of liking, and a very strong relationship (r = 0.92) was observed between perceived similarity to meat and overall sample liking ratings. Meat-like samples were also associated with positive emotional terms, whereas samples made from wholefoods were associated with negative emotional terms. Textural terms ('gluey/slimy', 'pasty/doughy') associated with wholefood products were also negative drivers for liking, and should be avoided in future PBMA products. In conclusion, the general population maintains a strong preference for PBMAs that are similar to meat, validating ongoing efforts to improve the meat-like properties of new and emerging products. PBMAs made from wholefoods require extensive product development to achieve consumer satisfaction across the category.

Abstract
This review examines the correlation between plant-based diets and athletic performance, with a specific emphasis on the vital aspect of optimizing micronutrients for athletes. In light of the increasing prevalence of plant-based nutrition among athletes due to its perceived advantages in terms of health, ethics, and the environment, this study investigates the ability of these diets to satisfy the demanding nutritional requirements essential for achieving optimal performance and facilitating recovery. The article emphasizes the significance of essential micronutrients such as iron, vitamin B12, calcium, vitamin D, zinc, and omega-3 fatty acids and also addressing the challenges with their absorption and bioavailability from plant sources. The review consolidates existing scientific knowledge to propose strategies for improving micronutrient consumption, comparing the effects of supplements against whole foods, and highlighting the significance of enhancing bioavailability. The proposal supports the implementation of personalized meal planning, with the assistance of sports nutritionists or dietitians, and is substantiated by case studies showcasing the success of plant-based athletes. Future research directions examine the long-term effects of plant-based diets on micronutrient status and athletic performance, as well as developing nutritional trends and technology. The review concludes that plant-based diets can meet athletes' nutritional demands and improve peak performance while aligning with personal and ethical values with strategic planning and professional guidance. This study intends to help athletes, coaches, and nutritionists understand plant-based nutrition for enhanced athletic performance.

Abstract
Cell-cultured meat holds significant environmental value as an alternative protein source. Throughout the 21st century, cell-cultured meat has progressively penetrated commercial markets. However, a systematic review encompassing the entire field needs improvement. Employing Citespace, Vosviewer, and R-Bibliometrix software, a bibliometric analysis was used to present the research progress and general development trends of 484 articles on cell-cultured meat from 2000 to 2022 based on countries, authors, institutions, and keywords. This analysis provides ideas for the future development of cell-cultured meat in different countries or regions worldwide. Research on cell-cultured meat from 2000 to 2022 has undergone two phases: fluctuating growth (2000-2013) and rapid growth (2013-2022). Noteworthy contributions to cell-cultured meat studies emerge from author groups in the United States of America, the United Kingdom, and China, with influential institutions like the University of Bath significantly impacting pertinent research. Furthermore, over the past two decades, research has leaned towards exploring topics such as "biomaterials", "cultured", "land use", "public opinion", "animal welfare", and "food safety". Furthermore, this study reveals differences in nomenclature between regions and institutions. "Cultured meat" is more popular in some countries than in other forms. Institutions in Asia use "cultured meat" more frequently; however, institutions in the Americas adopt "cultivated meat" and rarely adopt "in vitro meat", and institutions in the European region have no particularly prominent tendency towards a specific nomenclature. Future research should emphasize aligning the labeling of cell-cultured meat with effective management strategies and referencing regulatory policies across various countries. For the first time, we use three different bibliometric methods to analyze temporal and spatial variation in research on cellular meat. The results of this study have a multiplier effect. We provide a theoretical basis and a practical reference for the identification of alternatives in the dual context of "food crisis and food security" and "climate crisis". At the same time, we also provide a reference for the sustainable development of the food system.

Abstract
Although jellyfish represent a food source in Asia, limited attention has been devoted to investigating Western consumers' perception and acceptance. This study explored the role of jellyfish body parts and presentation form in determining consumer perception. A local consumer test with 106 untrained subjects (57.5% female, 18-45 years) was performed in Italy over two days on six samples of jellyfish (Rhopilema esculentum Kishinouye) differing in terms of body parts (umbrella and oral arms) and presentation form (minced, striped, and pieced). For each sample, participants expressed their overall liking and, through three check-all-that-apply tests, described their perceived sensory properties and emotions and potential preferred food pairings. The results showed a significant effect of presentation form on liking (with striped and minced samples liked more than pieced samples), 18 sensory properties, four emotions, and five food pairings. Moreover, different drivers of liking and emotions were observed for three clusters of subjects named "In favour of", "Against", and "Picky towards" eating jellyfish. In conclusion, this study found that at least one segment of consumers could accept jellyfish as novel food. Moreover, the provided results could be useful for developing innovative jellyfish-based products and dishes that meet consumers' expectations.

Abstract
There's been a change in citizens' attitudes towards beef consumption in high-income countries, resulting in a decline in its consumption. The COVID-19 pandemic may have impacted citizens' attitudes and behaviours towards beef consumption. This study aimed to investigate Chilean citizens' attitudes towards beef consumption during the initial 18 months of the pandemic. Socio-demographic characteristics and attitudes towards beef consumption were asked in two questionnaires done in 2020 (n = 1142) and 2021 (n = 1221). Citizens' attitudes to beef eating and production did not change between the start and more than a year after the outbreak of the COVID-19 pandemic. Participants not related with animal production, female, young, and non-meat consumers demonstrated more negative attitudes towards beef consumption and production. Half of the participants agreed that beef is bad for the environment, but only 30% agreed that beef is bad for human health. Half of participants had reduced beef consumption and 48% expressed intentions to reduce beef consumption in the future, primarily motivated by concerns related to animal welfare, the environment, and human health. The majority of participants (80%) thought that their fellow citizens should reduce their beef consumption but only 50% had confidence that this will occur. We conclude that Chilean consumers' attitudes to beef eating did not change due to the outbreak of the COVID-19 pandemic. Participants expressed strong concern about beef consumption both individually and socially, due to environmental, animal and health concerns, and believed Chileans should reduce beef consumption in the future but had low confidence that this will happen.

Wilks M, Crimston CR, Hornsey MJ. Meat and morality: The moral foundation of purity, but not harm, predicts attitudes toward cultured meat. Appetite 2024; 197:107297. [PMID: 38460906 DOI: 10.1016/j.appet.2024.107297] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Revised: 03/04/2024] [Accepted: 03/06/2024] [Indexed: 03/11/2024]
Abstract
Cultured meat (also referred to as cultivated, cell-based, or cell-cultured meat) is a novel food technology that is presented as a method of meat production without reliance on large-scale industrial farming. The pro-cultured meat narrative rests, in part, on a moral foundation: cultured meat is purported to alleviate the environmental and animal welfare harms associated with farmed meat. Despite this narrative, no research has examined which moral values underpin attitudes towards cultured meat. To examine this, we surveyed 1861 participants from the United States and Germany about their moral foundations and their attitudes towards cultured meat. In line with predictions, people who more strongly endorse moral values about purity (i.e., had higher scores on the purity subscale of the moral foundations scale) held more negative attitudes towards cultured meat. However, this relationship was much more consistent among participants from the United States than participants from Germany. Against predictions, attitudes towards cultured meat were not reliably associated with the extent to which people focus on harm as a moral foundation. The latter finding was particularly surprising in light of harm-reduction narratives around cultured meat. These findings demonstrate the need for a more nuanced discussion about, and understanding of, consumer concerns around cultured meat and the values that underpin them.

Abstract
Ensuring the supply of affordable, palatable, healthy, and sustainable nutrients to feed the growing population without transgressing the planetary boundaries remains a key challenge in the food science community. A dietary transition toward low-emission, plant-based foods, with less reliance on animal agriculture, is advocated for sustainability, health, and ethical reasons. A major hurdle for mainstream adoption of plant-based foods is their poor sensorial performance, such as nonjuicy and astringent textures as well as various off-flavors. This review presents the current understanding of astringency and oral friction of plant-based foods. It focuses on plant proteins and their application in plant-based meat and dairy analogs. In addition, the latest advances in the quantitative characterization of astringency using tribology, electrochemistry, and cellular tools are covered. Finally, we examine factors influencing astringency and propose easy-to-implement colloidal strategies that may mitigate astringency issues, thereby underpinning the design of the next generation of sustainable and pleasurable plant-based foods.

Front Nutr 2024; 11:1356210. [PMID: 38863584 PMCID: PMC11165137 DOI: 10.3389/fnut.2024.1356210] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Accepted: 05/14/2024] [Indexed: 06/13/2024] Open
Abstract
Introduction Food neophobia (FN) is a psychological trait that inhibits one's willingness to eat unfamiliar foods. It is related to the acceptance of insect foods and cultured meat, which are major protein alternatives to conventional meat, and is an important personality trait for understanding the near-future food industry. However, the factor structure of Pliner and Hobden's FN scale (FNS) is unstable due to respondents' cultural backgrounds. Thus, we aimed to develop a Japanese version based on the alternative FNS (FNS-A), the most recent revised version, and to examine its validity. Methods Four online surveys (preliminary 1: n = 202; preliminary 2: n = 207; main: n = 1,079; follow-up: n = 500) were conducted on the FNS-A. For the main survey, Japanese respondents (aged 20-69 years) answered the Japanese version of the FNS-A (J-FNS-A), their willingness to eat (WTE), and their familiarity with hamburgers containing regular protein foods (ground beef, tofu) and alternative protein foods (soy meat, cultured meat, cricket powder, algae powder, and mealworm powder). Results Consistent with the FNS-A, confirmatory factor analysis assuming a two-dimensional structure (approach and avoidance) showed satisfactory model fit indices. The mean J-FNS-A score (Cronbach's α for 8 items = 0.83) was 4.15 [standard deviation (SD) = 0.93]. J-FNS-A scores were not associated with age and gender, whereas a greater than moderate association was found with WTE hamburgers containing alternative protein foods (rs = -0.42 to -0.33). The strength of these negative associations increased as food familiarity decreased (r = 0.94). The test-retest reliability at 1 month was also satisfactory (r = 0.79). Discussion The validity of the J-FNS-A was confirmed. Higher J-FNS-A scores (mean = 41.51, SD = 9.25, converted to Pliner and Hobden's FNS score) of the respondents suggest that Japanese people prefer conservative foods. This scale could predict the negative attitudes toward foods with low familiarity, such as alternative proteins. The J-FNS-A appears to be a useful psychological tool for assessing Japanese food neophobia tendencies and predicting novel food choices of Japanese individuals.

Mertens E, Deriemaeker P, Van Beneden K. Analysis of the Nutritional Composition of Ready-to-Use Meat Alternatives in Belgium. Nutrients 2024; 16:1648. [PMID: 38892581 PMCID: PMC11175014 DOI: 10.3390/nu16111648] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2024] [Revised: 05/20/2024] [Accepted: 05/23/2024] [Indexed: 06/21/2024] Open
Abstract
BACKGROUND The interest in meat alternatives has increased over the years as people embrace more varied food choices because of different reasons. This study aims to analyse the nutritional composition of ready-to-use meat alternatives and compare them with meat (products). METHODS Nutritional composition values were collected in 2022 of all ready-to-use meat alternatives in Belgian supermarkets, as well as their animal-based counterparts. A one-sample t-test was performed to test the nutritional composition of ready-to-use meat alternatives against norm values, while an independent samples t-test was used to make the comparison with meat. RESULTS Minced meat and pieces/strips/cubes scored favourably on all norm values. Cheeseburgers/schnitzels, nut/seed burgers and sausages contained more than 10 g/100 g total fat. The saturated fat and salt content was lower than the norm value in each category. Legume burgers/falafel contained less than 10 g/100 g protein. Vegetarian/vegan minced meat and bacon contained fewer calories, total and saturated fat, and more fibre compared to their animal-based counterparts. CONCLUSIONS Minced meat and pieces/strips/cubes came out as the most favourable categories regarding nutritional composition norm values. Vegetarian/vegan steak came out the least favourable compared to steak, while vegetarian/vegan minced meat and vegetarian/vegan bacon came out the most favourable compared to their animal-based counterparts.

A Consumer Perspective on Plant-Based, Cell-Culture-Derived, and Insect-Based Alternatives. Foods 2024; 13:1627. [PMID: 38890856 PMCID: PMC11171576 DOI: 10.3390/foods13111627] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Revised: 05/19/2024] [Accepted: 05/21/2024] [Indexed: 06/20/2024] Open
Abstract
This study investigates consumer preference and acceptance of three meat alternatives-plant-based, lab-grown, and insect-based-as sustainable choices to meet the demands of a growing population and evolving food systems. Insights were gathered from European consumers regarding their perceptions and consumption patterns using a mixed-methods approach. The approach employed a questionnaire followed by focus group discussions conducted in Slovenia and the UK to understand the motivations and barriers behind their responses. The UK and Slovenia were chosen as they provided the highest response rates to the questionnaire and they have differing legislation. The results show that plant-based alternatives are the most familiar and accepted option, while lab-grown meat and insect-based products are less familiar and have lower acceptance rates. Moreover, they show that although sustainability factors are important to consumers, they are not their only concern; health and nutrition are the primary motivators for choosing meat alternatives. These are followed closely by sensory appeal, pricing, and a preference for natural, minimally processed options. Based on insights from the focus groups, strategies to overcome the barriers to the acceptance of meat alternatives should include targeted product categorisation and placement, educational campaigns, effective use of media, and greater transparency in product information.

Characteristics of built food environments associated with alternative protein food choices: a systematic review. Int J Behav Nutr Phys Act 2024; 21:58. [PMID: 38755618 PMCID: PMC11100026 DOI: 10.1186/s12966-024-01606-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Accepted: 05/01/2024] [Indexed: 05/18/2024] Open
Abstract
BACKGROUND This systematic review contributes to the understanding of the characteristics of built food environments that may be associated with choices of alternative protein foods (APF). Using the built food environment typology proposed by Downs et al., we investigated various environmental structures (e.g., supermarkets, other retailers, farmers' markets, restaurants, schools, and online vendors) and the characteristics that may facilitate or hinder consumers' choices. For example, facilitators and barriers may refer to the physical characteristics of environmental structures, food presentation practices, the organizational strategies or policies operating in the setting, or the actions that retailers or consumers engage in while selling, serving, choosing, trying, or purchasing APF in these environmental structures. METHODS A systematic review (PROSPERO database preregistration; no. CRD42023388700) was conducted by searching 13 databases for peer-reviewed journals focusing on the fields of economics and business, agriculture, medical sciences, and social sciences. Data searches, coding, and quality evaluations were conducted by at least 2 researchers. A total of 31 papers (36 original studies) were included. The risk of bias was evaluated with the Joanna Briggs Institute quality evaluation tool, with 24 publications presenting low risk of bias. RESULTS The findings indicate that perceived and actual availability facilitate consumers' APF choices across a built food environment. Several barriers/facilitators were associated with APF choices in specific types of built food environments: the way food is presented in produce sections (supermarkets), consumer habits in terms of green and specialty shopping (grocery stores), and mismatches among retailer actions in regard to making APF available in one type of food environment structure (e-commerce) and consumers' preferences for APF being available in other food environment structures (supermarkets, grocery stores). The effect of a barrier/facilitator may depend on the APF type; for example, social norms regarding masculinity were a barrier affecting plant-based APF choices in restaurants, but these norms were not a barrier affecting the choice of insect-based APF in restaurants. CONCLUSIONS Addressing barriers/facilitators identified in this review will help in developing environment-matching interventions that aim to make alternative proteins mainstream.

Abstract
This review article aims to provide an up-to-date overview of the main determinants of consumers' acceptance of novel foods (new foods and ingredients) in the EU with emphasis on product's intrinsic properties (sensory characteristics) and individual factors (socio-demographics, perceptive, psychological) by adopting a systematic approach following the PRISMA methodology. Case studies on terrestrial (i.e., insects, cultured meat and other animal origin products, plant-based food including mushrooms, plant-based analogues, pulses, and cereals) and aquatic systems (i.e., algae and jellyfish) are included focusing on age-related and cross-national differences in consumer acceptance of novel foods and ingredients. General trends have emerged that are common to all the novel foods analysed, regardless of their aquatic or terrestrial origin. Aspects such as food neophobia, unfamiliarity, and poor knowledge of the product are important barriers to the consumption of novel foods, while healthiness and environmental sustainability perception are drivers of acceptance. Sensory properties are challenging for more familiar ingredients such as plant-based food (e.g., novel food made by pulses, mushrooms, cereals and pseudocereals). Results are discussed in terms of feasibility of introducing these products in the EU food systems highlighting strategies that can encourage the use of new ingredients or novel foods.

Abstract
Faba bean is a promising source of ingredients for the production of meat analogs. However, sensory properties of faba bean, especially the bitter taste of the protein concentrate, restrict its use. Our aim was to assess the feasibility of two types of faba bean ingredients-flour (from germinated, gently heat-treated beans) and groat (from non-germinated, roasted beans)-in combination with pea protein isolate and oat fiber concentrate for producing meat analogs using high-moisture extrusion. We produced six samples using varying recipes, while maintaining constant process parameters. An untrained panel (55 participants) evaluated the samples for key sensory attributes (check-all-that-apply) and rated their pleasantness. The water absorption capacity and mechanical properties of the samples were assessed using instrumental measurements. The samples were frequently described as 'beany' and 'tasteless', but very rarely as 'bitter'. The most frequently cited attributes for mouthfeel varied between the samples containing 30% ('tough', 'gummy') and 50% ('crumbly', 'floury') of faba bean flour/groat and were associated with corresponding mechanical properties. On average, the sample containing a blend of faba bean groat and pea protein isolate (50% each) appeared to be the most pleasant. Our results suggest that faba bean groat with pea protein isolate enables the production of fibrous meat analogs with acceptable taste and texture, without the bitter off-taste.

Abstract
Pea proteins are gaining increased interest from both the food industry as well as from consumers. Pea protein isolates (PPI) excel at forming meat-like textures upon heating while pea protein concentrates (PPC) are more challenging to transform into highly sought-after foods. PPCs are richer in dietary fibers (DF) and are more sustainable to produce than PPI. In this work, degradative enzymes were used to modify the functionality of PPC-water blends with a focus on texturization upon heating. Three enzyme solutions containing β-glucanases, hemicellulases, pectinases, xylanase, and cellulases were added to 65 wt% PPC blends. The effect of these enzymatic pretreatments was measured by monitoring the torque in a mixing reactor during blending, differential scanning calorimetry (DSC), high-pressure shear rheology (HPSR), and DF content and size analysis. Four endothermic peaks were detected in the DSC thermograms of PPC, namely at 63 °C, 77 °C, 105 °C and 123 °C. The first three peaks were attributed to phase transition and gelation temperatures of the starches and proteins constituting PPC. No endothermic peaks were measured for PPI blends. Enzyme solutions containing β-glucanases, hemicellulases, pectinases, and xylanases increased the endothermic energy of all peaks, hinting at an effect on the gelation properties of PPC. The same enzymes decreased the resistance to flow of PPC blends and induced a shift of the weight average molecular weight (Mw) distribution of soluble dietary fibers (SDF) towards smaller values while increasing the fraction of SDF by decreasing the insoluble dietary fiber (IDF) content. The solution containing cellulases did not change the DSC results or the viscosity of the PPC mixture, nor did it affect the IDF and SDF contents. On the other hand HPSR measurements of heated PPC samples up to 125 °C showed that all tested enzyme solutions decreased the complex viscosity of PPC-water blends to values similar to PPI-water blends. We demonstrated that degradative enzymes can enhance the functionality of less refined protein-rich ingredients based on pea and other vegetal sources. Using optimized enzyme blends for targeted applications can prove to be a key changer in the development and improvement of sustainable protein-rich foods.

Abstract
Cultured meat has been gaining popularity as a solution to the increasing problem of food insecurity. Although research on cultured meat started later compared to other alternative meats, the industry is growing rapidly every year, with developed products evaluated as being most similar to conventional meat. Studies on cultured meat production techniques, such as culturing new animal cells and developing medium sera and scaffolds, are being conducted intensively and diversely. However, active in-depth research on the quality characteristics of cultured meat, including studies on the sensory and storage properties that directly influence consumer preferences, is still lacking. Additionally, studies on the combination or ratio of fat cells to muscle cells and on the improvement of microbiota, protein degradation, and fatty acid degradation remain to be conducted. By actively investigating these research topics, we aim to verify the quality and safety of cultured meats, ultimately improving the consumer preference for cultured meat products.

McClements DJ. Novel animal product substitutes: A new category of plant-based alternatives to meat, seafood, egg, and dairy products. Compr Rev Food Sci Food Saf 2024; 23:e313330. [PMID: 38551190 DOI: 10.1111/1541-4337.13330] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Revised: 02/05/2024] [Accepted: 03/08/2024] [Indexed: 04/02/2024]
Abstract
Many consumers are adopting plant-centric diets to address the adverse effects of livestock production on the environment, health, and animal welfare. Processed plant-based foods, including animal product analogs (such as meat, seafood, egg, or dairy analogs) and traditional animal product substitutes (such as tofu, seitan, or tempeh), may not be desirable to a broad spectrum of consumers. This article introduces a new category of plant-based foods specifically designed to overcome the limitations of current animal product analogs and substitutes: novel animal product substitutes (NAPS). NAPS are designed to contain high levels of nutrients to be encouraged (such as proteins, omega-3 fatty acids, dietary fibers, vitamins, and minerals) and low levels of nutrients to be discouraged (such as salt, sugar, and saturated fat). Moreover, they may be designed to have a wide range of appearances, textures, mouthfeels, and flavors. For instance, they could be red, orange, green, yellow, blue, or beige; they could be spheres, ovals, cubes, or pyramids; they could be hard/soft or brittle/pliable; and they could be lemon, thyme, curry, or chili flavored. Consequently, there is great flexibility in creating NAPS that could be eaten in situations where animal products are normally consumed, for example, with pasta, rice, potatoes, bread, soups, or salads. This article reviews the science behind the formulation of NAPS, highlights factors impacting their appearance, texture, flavor, and nutritional profile, and discusses methods that can be used to formulate, produce, and characterize them. Finally, it stresses the need for further studies on this new category of foods, especially on their sensory and consumer aspects.

Abstract
A shift from predominantly animal-based to plant-based consumption can benefit both planetary and public health. Nudging may help to promote such a shift. This study investigated nudge effects on plant-based alternatives to meat and dairy in an online supermarket. We conducted a two-arm, parallel-group, randomized controlled real-life online supermarket trial. Each customer transaction was randomized to a control arm (regular online supermarket) or an intervention arm (addition of placement, hedonic property and dynamic social norm nudges promoting meat and dairy alternatives). Outcomes were the aggregate of meat and dairy alternative purchases (primary outcome), the number of meat purchases, dairy purchases, meat alternative purchases, and dairy alternative purchases (secondary), and retailer revenue (tertiary). Generalized linear mixed models with a Conway-Maxwell Poisson distribution were used to estimate incidence rate ratios (IRRs). Analyzed data included 8488 transactions by participants (n = 4,266 control arm, n = 4,222 intervention arm), out of which 2,411 (66%) were aged above 45 years, 5,660 (67%) were females, and 1,970 (23%) lived in socially disadvantaged neighborhoods. Intervention arm participants purchased 10% (IRR 1.10 (95% CI 0.99-1.23)) more meat and dairy alternatives and 16% (1.16 (0.99-1.36)) more meat alternatives than control arm participants, although these findings are not statistically significant. There was no difference in dairy alternative purchases (1.00 (0.90-1.10)). Intervention arm participants purchased 3% less meats (0.97 (0.93-1.02)) and 2% less dairy products (0.98 (0.95-1.02)) than control participants. Retailer revenue was not affected (0.98 (0.95-1.01)). Online nudging strategies alone did not lead to a statistically significant higher amount of plant-based purchases, but replication of this work is needed with increased study power. Future studies should also consider nudging strategies as part of a broader set of policies to promote plant-based purchases. TRIAL REGISTRATION: Prospectively registered on 14th of May 2022.

Abstract
Cultured foods have the potential to profoundly transform the food industry. However, most current research focuses on cultured meat, neglecting other cultured products and begging the question of whether different promotional approaches are suited for certain types of cultured food products than others. To bridge this knowledge gap, we carried out two studies to explore how product type (cultured meat vs. cultured fruit) and benefit type (ethical vs. product attributes such as sensory and nutritional advantages) interact in determining consumers' willingness to try the products. Study 1 findings indicate that emphasizing ethical benefits is more effective for promoting cultured meat, whereas highlighting product benefits is more effective for promoting cultured fruit. We found that curiosity, a strong behavioral motivator, mediates the interactive effect of product type and benefit type on willingness to try. This research underscores the need for marketing messages to be tailored to the distinct cultured product types and enriches the literature on curiosity as an important mechanism in the context of cultured food acceptance.

Abstract
Considering the prevalent strain on environmental resources imparted by existing food systems, prioritizing environmental sustainability is an imperative course of action. Subsequently, the shift towards sustainable production and consumption patterns engenders an escalating demand for environmentally conscious food systems. Thus, 3D-printed food technology surfaces are a promising solution noted for their efficacy in curtailing food waste, bolstering environmental sustainability, and imparting innovative strategies to the food supply chain. Herein, we amalgamate the theory of planned behavior (TPB) framework with several variables, namely 'sensory appeal', 'food neophobia', 'perceived health risk', and 'environmental friendliness' to probe the behavioral intentions of Taiwanese university students' perceptions about 3D-printed food. Employing the snowball sampling method, 370 questionnaires were disseminated, out of which 319, constituting an effective retrieval rate of 86.2%, were deemed valid. Statistical analysis produced intriguing findings. Consumers' inclination to purchase 3D-printed food is substantially determined by their attitudes, subjective norms, sensory appeal, food neophobia, perceived health risks, and environmental friendliness. Contrary to our initial hypothesis, perceived behavioral control did not exhibit a significant impact on consumers' propensity to purchase 3D-printed food. Therefore, businesses should focus on magnifying the sensory appeal of 3D-printed food, coupled with precise nutritional labeling, to bolster consumer interest, enhance acceptance, and augment behavioral intentions. This study sheds light on the potential for the development of 3D-printed food in Taiwan, providing an indispensable reference for future endeavors in Taiwan's 3D-printed food industry.

Abstract
Integrating algae into poultry diets offers a promising avenue for enhancing nutrition, boosting sustainability efforts, and potentially stimulating disease resistance. This comprehensive review delves into the essence, diversity, chemical composition, and nutritional merits of algae, spotlighting their emergence as innovative nutrient sources and health supplements for poultry. The growing interest in algae within poultry nutrition stems from their diverse nutritional profile, boasting a rich array of proteins, lipids, amino acids, vitamins, minerals, and antioxidants, thus positioning them as valuable feed constituents. A key highlight of incorporating both macroalgae and microalgae lies in their elevated protein content, with microalgae varieties like Spirulina and Chlorella exhibiting protein levels of up to 50-70%, outperforming traditional sources like soybean meal. This premium protein source not only furnishes vital amino acids crucial for muscular development and overall health in poultry but also serves as an exceptional reservoir of omega-3 fatty acids, notably eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), presenting multiple health benefits for both poultry and consumers alike. Moreover, algae boast antioxidant properties attributed to bioactive compounds like phycocyanin and astaxanthin, mitigating oxidative stress and boosting the bird's immune response, thereby fostering robust health and disease resilience. Incorporating macroalgae and microalgae into poultry diets yields positive impacts on performance metrics. Research evidence underscores the enhancement of growth rates, feed conversion ratios, carcass quality, and meat attributes in broilers, while in layers, supplementation promotes increased egg production, superior egg quality, and increased concentrations of beneficial nutrients such as omega-3 fatty acids. Furthermore, algae hold promise for mitigating the environmental footprint of poultry production, though significant outcomes from trials remain sporadic, necessitating further research to elucidate optimal dosages and blends for different algae species in poultry diets. Standardizing the composition of algae utilized in research is imperative, paving the way for potential applications in poultry nutrition as growth stimulants and substitutes for antibiotics. Nonetheless, a deeper understanding of dosage, combination, and mechanism of action through rigorous scientific investigation is key to unlocking algae's full potential within poultry nutrition.

Abstract
Entomophagy studies mainly focused on insects as a generic category, rarely considering insect species. This study investigated the: i) affective response to specific edible insect species; ii) sensory properties characterizing the tested insects and their role in driving preferences and food paring. A sensory test (85 consumers, 56.5 % female, 19-73 years) was performed on seven dried whole edible insects at the adult (weaver ants, crickets, grasshoppers), larva (bamboo worms, morio worms, sago worms) and pupae stage (silkworms). For each species, consumers expressed their liking and, through three check-all-that-apply tests, described the perceived sensory properties, the perceived emotions, and their potential food pairings. Results showed a significant effect of the species on all variables. Bamboo worms, weaver ants and grasshoppers resulted the most accepted, followed by morio worms, crickets, and silkworms, while the sago worms were the most disliked. Numerous sensory attributes significantly discriminated among insect species and the drivers of liking and sensory attributes associated to the food pairings were identified. However, two clusters with different preferences and drivers of liking were observed. Moreover, a gender effect was found: i) males associated insects with emotions like calm and wild, while females with glad and pleased; ii) males and females would pair different foods with the insect species. In conclusion, this study provided new knowledge useful for researchers and food industry to develop future insect-based foods and dishes able to meet the expectations of different consumers segments.

Abstract
Growing evidence on medical cannabis has moved its legislation forward in various countries, which has increased research on stakeholder reactions. While various studies looked at experts and users, research on public perceptions is scarce. This study aims to (1) examine the relationships between knowledge, perceptions, and behavioral intention toward medical cannabis, and (2) identify and profile key segments within the general public. An online survey was conducted among 656 respondents in Belgium. Findings showed that both subjective and objective knowledge are relatively poor, while risk/benefit perceptions and behavioral intention are much more positive. Subjective and objective knowledge as well as social trust have a positive influence on benefit perceptions and a negative influence on risk perceptions. In turn, risk and benefit perceptions are key determinants of behavioral intention, but in opposite directions. Furthermore, cluster analysis identified a cautious (23% of the sample), positive (50%), and enthusiastic cluster (27%). In terms of socio-demographic profile, older and highly educated people were significantly more represented in the latter two clusters. While our study demonstrated that cannabis is well accepted for medical purposes, research is needed to further validate the relationships between knowledge, perceptions, and (intended) behavior in different settings and policy contexts.

Abstract
The food insecurity due to a vertical increase in the global population urgently demands substantial advancements in the agricultural sector and to identify sustainable affordable sources of nutrition, particularly proteins. Single-cell protein (SCP) has been revealed as the dried biomass of microorganisms such as algae, yeast, and bacteria cultivated in a controlled environment. Production of SCP is a promising alternative to conventional protein sources like soy and meat, due to quicker production, minimal land requirement, and flexibility to various climatic conditions. In addition to protein production, it also contributes to waste management by converting it into food and feed for both human and animal consumption. This article provides an overview of SCP production, including its benefits, safety, acceptability, and cost, as well as limitations that constrains its maximum use. Furthermore, this review criticizes the downstream processing of SCP, encompassing cell wall disruption, removal of nucleic acid, harvesting of biomass, drying, packaging, storage, and transportation. The potential applications of SCP, such as in food and feed as well as in the production of bioplastics, emulsifiers, and as flavoring agents for baked food, soup, and salad, are also discussed.

Abstract
Healthy sustainable diets have the power to improve dietary intakes and environmental resource use. However, recommendations for improving food choices need to consider the effects of any changes across multiple dimensions of health, environmental sustainability, and dietary cost to promote long-lasting behaviour change. The aim of this study was to identify differences between original diets, and the diets that can be achieved through the implementation of select small dietary changes towards sustainability. Twelve hypothetical sustainable actions were investigated for the potential effects of these actions on dietary markers (protein, saturated fat, sugars, salt, iron, and calcium), environmental footprints (greenhouse gas emissions, freshwater withdrawals, and land use), and dietary cost. Dietary data from 1235 individuals, aged 19-94 years, participating in the UK National Diet and Nutrition Survey (2017/19) provided the original diet. Dietary changes were implemented as required by each sustainable action, and differences between the original diet and each new diet were investigated. Results revealed benefits to dietary markers and environmental characteristics from eleven sustainable actions (range: F(1,728) = 5.80, p < .001 to F(1,506) = 435.04, p < .001), but effects were stronger for some actions than for others. Greatest benefits for all three outcomes were found for actions which reduced meat consumption and/or replaced meat with pulses or eggs. The remaining sustainable actions tended to be beneficial for improving outcomes individually or to some degree. Our results demonstrate the possible impacts of a number of small sustainable dietary actions for dietary, environmental, and cost outcomes, and provide a hierarchy of actions based on benefit. Findings may facilitate dietary behaviours towards improved health, whilst also offering fruitful contributions towards environmental footprint targets in the UK.

Abstract
The effect that protein-bioactive interactions may have on diffusion kinetics in foods and nutraceuticals was investigated by examining the diffusion kinetics of phenolic compounds (ferulic acid and epicatechin) of varying size, in the presence and absence of bovine β-casein. In the presence of the protein, the diffusion rate for ferulic acid and epicatechin was shown to decrease from 2.76 × 10-11 and 1.33 × 10-11 to 8.51 × 10-12 and 1.00 × 10-12 m2/s, respectively. The magnitude of the decrease in diffusion rate appears to be governed by interaction strength, with pulling simulations and umbrella sampling determining binding energies of -4.6 and -6.7 kcal mol-1 for protein-ferulic acid and protein-epicatechin interactions. This outcome indicates that dissociation of the bioactive from the delivery matrix may be the rate limiting process for diffusion in low solid systems. This work offers valuable insights for the use of pulling/umbrella simulations in understanding the impact of interactions on diffusion in foods and nutraceuticals.

Abstract
Men historically consume more meat than women, show fewer intentions to reduce meat consumption, and are underrepresented among vegans and vegetarians. Eating meat strongly aligns with normative masculinities, decisively affirming that "real men" eat meat and subordinating men who choose to be veg*n (vegan or vegetarian). The emergence of meat alternatives and increasing environmental concerns may contest these long-standing masculine norms and hierarchies. The current scoping review addresses the research question what are the connections between masculinities and men's attitudes and behaviors toward meat consumption and veg*nism? Using keywords derived from two key concepts, "men" and "meat," 39 articles were selected and analyzed to inductively derive three thematic findings; (a) Meat as Masculine, (b) Veg*n Men as Othered, and (c) Veg*nism as Contemporary Masculinity. Meat as Masculine included how men's gendered identities, defenses, and physicalities were entwined with meat consumption. Veg*n Men as Othered explored the social and cultural challenges faced by men who adopt meatless diets, including perceptions of emasculation. Veg*nism as Contemporary Masculinity was claimed by men who eschewed meat in their diets and advocated for veg*nism as legitimate masculine capital through linkages to physical strength, rationality, self-determination, courage, and discipline. In light of the growing concern about the ecological impact of meat production and the adverse health outcomes associated with its excessive consumption, this review summarizes empirical connections between masculinities and the consumption of meat to consider directions for future men's health promotion research, policy, and practice.

Development of the lexicon, trained panel validation and sensory profiling of new ready-to-eat plant-based " meatballs" in tomato sauce. OPEN RESEARCH EUROPE 2024; 2:145.

Abstract
Background Providing educational content for children and parents can promote healthy nutritional habits. During the TITAN project, a pilot digital contest where participants have to developed ready-to-eat meatballs in sauce, using only plant-based ingredients, will be tested. The objective of this study was to develop the lexicon needed to objectively assess the sensory profile of this product. Methods Eight judges were recruited and trained. Thirteen 1-hour sessions took place over three months. The steps followed were the selection of commercial reference, generation of descriptors, training of the panel, validation of the trained panel and product characterisation. The judges chose one commercial reference (using simple hedonic evaluation) to serve as a reference. The accepted intensity scale for the generated descriptors was from 0 (low intensity) to 9 (very intense). To test the first versions of the game, food product developers involved in the project, acted as participants, and used a mix of lentils, quinoa, and oats to enhance the commercial version. R-project software was used to analyse the performance of the panel and the sensory profiles. Results A glossary with 14 descriptors was generated. The discriminatory capacity of the panel was confirmed by examining the significance of the product effect (p < 0.05). The product-judge interaction was not significant (p > 0.05) for most of the evaluated attributes, indicating a good degree of panel agreement. Overall, the panel was considered reproducible after 9 sessions. Although the appearance, firmness, fragility and chewiness were considered similar to the reference, juiciness and taste (understood as meaty flavour) of the new product were deemed improved. Conclusions According to the panel, two of the most appreciated attributes associated with meat analogues, juiciness and taste, were improved compared to the commercial reference. Therefore, the first approach for further development of the contest/game was validated.

Effects of repeated home-use, recipe inspiration and meal context on perception of plant-based meat analogues. Appetite 2024; 193:107135. [PMID: 38008190 DOI: 10.1016/j.appet.2023.107135] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 11/07/2023] [Accepted: 11/20/2023] [Indexed: 11/28/2023]
Abstract
Plant-based meat analogues (PBMA) may help consumers in shifting towards more plant-based diets, but PBMA are not widely used yet, and little is known about their longer-term acceptance. This study investigated whether consumer acceptance of PBMA changed with repeated home-use, and whether providing recipe suggestions in the form of meal boxes could influence PBMA acceptance. To this end, Dutch regular meat eaters (n = 61) prepared, consumed and evaluated two meals (one from a meal box, one self-created) with PBMA (PB mince and PB chicken, counterbalanced across meal types) per week at home for four weeks. As a secondary objective, potential longer-term effects of repeated home-use of PBMA on meat (analogue) consumption habits and attitudes (e.g. motives for choosing PBMA, attitudes toward eating less meat) were assessed in a pre-vs post-intervention survey. Responses were compared with a control group of consumers not participating in the home-use study (n = 179). Results provided no evidence that PBMA liking changed with repeated home-use, nor that the provision of meal boxes increased liking of PBMA. Instead, PBMA liking was strongly influenced by the meal context, which may have overruled potential effects of repeated exposure. Findings from the pre- vs. post-intervention survey suggest that repeated exposure may stimulate longer-term consumption of PBMA, although more seems needed to bring about a structural shift toward a less animal-based consumption pattern. Future research should investigate whether more sophisticated recipes that provide a suitable meal context for PBMA and elevate consumers' meal experiences may improve PBMA acceptance and facilitate the transition toward more sustainable diets.

Curr Dev Nutr 2024; 8:101998.

Abstract
Agroecology has been proposed as a holistic approach to transform food systems that meet global food requirements with favorable environmental and social impacts. Agroecology relies on science, practices, and social movements that emphasize ecological principles, local knowledge, culture, and traditions to increase the sustainability and equity of the food system. Agroecological practices have demonstrated positive outcomes on food security and nutrition in low- and middle-income countries (LMICs). Agroecology principles can be applied across the food system and could facilitate the integration of certain alternative protein (AP) foods to address multiple issues. In this perspective, agroecological principles were analyzed to compare the suitability of different AP sources: unprocessed/minimally processed legumes, plant-based meats, edible insects, macroalgae (seaweed), fungal biomass, and cultivated meat. Considerations were identified for the feasibility of AP adoption in LMICs within an agroecological framework to provide nutrient-rich and sustainable diets while addressing other principles such as fairness and economic diversity. From this analysis, legumes, simplified plant-based meat analogs such as texturized plant proteins with minimal additives, edible insects, and macroalgae (location dependent) would make excellent nutritional contributions alongside animal-sourced food within LMICs within an agroecological framework. In contrast, highly processed plant-based meats, fungal biomass, and cultivated meat do not align well with agroecological principles for large-scale human consumption within LMICs. Furthermore, the production facilities to make these foods require robust capital investment and there may be issues related to who owns the intellectual property of these technologies. The NOVA classification system categorizes food based on the degree of processing. Our assessment suggests that foods with lower NOVA classification of unprocessed and minimally processed best fit the agroecological principles related to nutrition, agroecosystem, and societal demands for sustainable food systems.

Generating Demand for Alternative Protein in Low- and Middle- Income Countries: Opportunities and Experiences from Nutritious and Sustainable Market Solutions. Curr Dev Nutr 2024; 8:101996.

Abstract
Protein consumption and the demand for high-value nutritional products is growing rapidly in emerging markets. The projected growth of the alternative protein industry may position it well to meet this demand while addressing environmental sustainability and ethical standards. However, adoption of alternative protein products over traditional animal-sourced proteins is not always a clear choice, with factors such as consumer preferences and habitual behaviors influencing consumer decisions. Insights and considerations associated with generating demand for alternative protein products in low- and middle-income countries (LMIC) were identified through 3 case studies: the OBAASIMA Project in Ghana, the Egg Initiative in Ethiopia, and the World Food Programme Farming Coalition project in Armenia. Key findings emphasize the importance of local sourcing, positive messaging, and integration within existing diets and behaviors. Therefore, these factors will be essential for the adoption of novel alternative protein products in LMIC.

Abstract
Despite growing commercial interest in novel foods, there are few studies that analyse consumer willingness to purchase them as pet food. This study aimed to test whether consumers are willing to accept the use of foods with insect-based ingredients, which are found to be poorly accepted for human consumption, to feed their pets. In our case study, we analysed the willingness of 400 Italian dog and/or cat caregivers to pay for pet foods containing insect proteins, as measured by the Multiple Price List methodology. We also explored the role of food neophobia, attention to environmental sustainability, and empathy toward one's pet. The results of the study pointed out that the usual determinants of acceptance in the consumption of novel foods, such as food neophobia and attention to environmental sustainability, play an important role even when the purchase is for the household pet, and that empathy as an expression of the pet caregiver's personal relationship with their pet becomes an additional factor. Insect-based pet foods proved to be attractive for purchase only when consumers are well informed about the product's properties in terms of sustainability and healthiness for their pets.

Abstract
An understanding regarding impacts of growth-related myopathies, i.e., white striping (WS) and wooden breast (WB), on the quality of dietary protein from cooked chicken breast is still limited. This study aimed at comparing protein content and in vitro protein digestion and estimating the in vitro protein digestibility corrected amino acid score (PDCAAS) of cooked chicken meat exhibiting different abnormality levels (i.e., normal, WS, and WS + WB). The results show that the WS + WB samples exhibited lower protein content, greater cooking loss, and greater lipid oxidation than those of normal samples (p < 0.05). No differences in protein carbonyls or the myofibril fragmentation index were found (p ≥ 0.05). Cooked samples were hydrolyzed in vitro using digestive enzyme mixtures that subsequently mimicked the enzymatic reactions in oral, gastric, and intestinal routes. The WS + WB samples exhibited greater values of free NH2 and degree of hydrolysis than the others at all digestion phases (p < 0.05), suggesting a greater proteolytic susceptibility. The in vitro PDCAAS of the WS + WB samples was greater than that of the other samples for pre-school children, school children, and adults (p < 0.05). Overall, the findings suggest that the cooked chicken breast with the WS + WB condition might provide greater protein digestibility and availability than WS and normal chicken breasts.
