Nervo C, Ricci M, Torri L. Understanding consumers attitude towards insects as food: Influence of insect species on liking, emotions, sensory perception and food pairing. Food Res Int 2024; 182:114174. [PMID: 38519187 DOI: 10.1016/j.foodres.2024.114174] [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: 08/01/2023] [Revised: 02/20/2024] [Accepted: 02/28/2024] [Indexed: 03/24/2024]
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
As a source of protein and other nutrients for a growing population, edible insect production offers environmental and sustainability advantages over traditional meat production. Although around 2 billion people consume insects worldwide, Western consumers are still reluctant to practice entomophagy, hindered largely by neophobia and negative emotions. In addition to sensory quality and safety, an informational component may be crucial to consumers' decision making involving insect consumption. In this study, three different information types, namely text, image, and a tangible product, were used to convey information about chocolate chip cookies (CCCs) containing cricket flour. The nature of the information was related to the ingredient usage level (5%), the type of insect (cricket), nutritional values, sustainability benefits, packaging, celebrity endorsement, and/or visual appearance of an actual product. Consumers' willingness to consume (WTC), acceptance, and purchase intent (PI) were measured in response to each informed condition. Once informed of the insect ingredient, all scores significantly (α = 0.05) dropped. The lowest WTC (1.97 ± 1.06, Text), acceptance (3.55 ± 2.23, Image), and PI (1.85 ± 1.05, Text) scores were found after identifying cricket as the insect ingredient. Compared to other informed conditions, the presentation of a real chocolate chip cookie containing insects achieved the highest scores on all affective scores (WTC: 3.4 ± 1.04, acceptance: 6.17 ± 1.89, PI: 3.07 ± 1.09). The greatest improvement in scores was observed after information about nutrition and sustainability benefits (based on ANOVA), which was more impactful for males than females (based on a t-test). Celebrity endorsement did not have a significant effect. The presentation of the actual CCC containing cricket flour (for visual observation only) significantly increased WTC, acceptance, and PI compared to presenting text and images alone. Acceptance, WTC, and certain information cues were significant predictors of PI for CCCs containing cricket flour.

Abstract
Edible insects can diversify diets, improve livelihoods, contribute to food and nutrition security, and have a smaller ecological impact. The European Union has categorized insects as novel food, and recently, in 2021 and 2022, two species, Tenebrio molitor and Acheta domesticus, were authorized for commercialization. The acceptance and perception of food risk derived from insect consumption vary depending on factors impacting insect consumption acceptability, including neophobic tendencies, gender differences, familiarity, and gastronomic perceptions. The aim of this work was to evaluate the perception and acceptance of edible insects by exploring these factors. This study was carried out on higher-education students from universities in Valencia (Spain). The students recognized insects' high nutritional value, particularly protein content, and had varying levels of knowledge about specific nutritional components. In terms of labeling and marketing, removing health and sustainability benefits from packaging can improve consumer responses. Most respondents prefer clear labeling of insect derivatives, quality certification seals, and complete information about insect content. Students consider marketing and knowledge to be significant influencers of insect consumption. In summary, this text highlights the multifaceted nature of insect consumption acceptability. These insights offer valuable perspectives on insect consumption dynamics.

Legal situation and consumer acceptance of insects being eaten as human food in different nations across the world-A comprehensive review. Compr Rev Food Sci Food Saf 2023; 22:4786-4830. [PMID: 37823805 DOI: 10.1111/1541-4337.13243] [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: 04/08/2023] [Revised: 08/06/2023] [Accepted: 08/28/2023] [Indexed: 10/13/2023]
Abstract
Insect consumption is a traditional practice in many countries. Currently, the urgent need for ensuring food sustainability and the high pressure from degrading environment are urging food scientists to rethink the possibility of introducing edible insects as a promising food type. However, due to the lack of the standardized legislative rules and the adequate scientific data that demonstrate the safety of edible insects, many countries still consider it a grey area to introduce edible insects into food supply chains. In this review, we comprehensively reviewed the legal situation, consumer willingness, acceptance, and the knowledge on edible insect harvesting, processing as well as their safety concerns. We found that, despite the great advantage of introducing edible insects in food supply chains, the legal situation and consumer acceptance for edible insects are still unsatisfactory and vary considerably in different countries, which mostly depend on geographical locations and cultural backgrounds involving psychological, social, religious, and anthropological factors. Besides, the safety concern of edible insect consumption is still a major issue hurdling the promotion of edible insects, which is particularly concerning for countries with no practice in consuming insects. Fortunately, the situation is improving. So far, some commercial insect products like energy bars, burgers, and snack foods have emerged in the market. Furthermore, the European Union has also recently issued a specific item for regulating new foods, which is believed to establish an authorized procedure to promote insect-based foods and should be an important step for marketizing edible insects in the near future.

Abstract
Edible insects could be a promising answer to the question of how to feed a growing human population with a healthier and more sustainable source of protein. Despite the increasing interest in entomophagy in food science and industry, however, consumer acceptance for insect-based food products remains low in Western countries. This systematic review provides a comprehensive and timely overview of studies relevant for researchers, practitioners and other stakeholders involved in the marketing of these products. Reviewing data from 45 selected studies, we focus on marketing measures tested for their influence on Western consumers' preference, acceptance, willingness to try, eat and/or buy insect-based food products. Organising the findings according to the 4Ps of the marketing mix framework, five main ways of enhancing the appeal and acceptance of insect-based food products are discussed: 1) developing product attributes that align with the specific preferences of target consumers; 2) a more subtle labelling of the presence of insects; 3) using value-added or competition-based pricing strategies; 4) making products consistently available in the marketplace; and 5) promoting products more effectively through advertising, tasting activities, and social influence. The heterogeneity we find among the studies, whether due to differences in the products researched, in sampling countries, or in data-collection methods, indicates key research gaps for future studies to address.

Abstract
Social marketing campaigns are widely used to inform, educate, communicate, and promote healthy behaviors that add benefits to the individual, but also to society and the environment. Considering the low cost and high quality of insect-based food, this research aims to identify the main factors which can be used by social marketing campaigns to help people to try new foods, such as insect-based food. Although it is considered an important alternative to protein, there are a few countries that have not experienced it. In many Western countries, insect-based food is perceived as being disgusting. Neophobia is also a barrier to trying these foods. The main goal is to analyze if social marketing campaigns might influence perception (familiarity, preparation, visual, and information). Our model proves this assumption because we obtained high path coefficients, indicating that perception influences social beliefs, individual beliefs, and consumption intention. Thus, they will increase the consumption intention.

Abstract
Catfish (Ictalurus punctatus) skins, as filleting byproduct, were developed into a crispy snack food via air-frying. Consumers rated catfish skin chips (CSC) across sensory modalities (9-point hedonic scales, a just-about-right scale, and "yes/no" for purchase intent, PI) for Plain-, Lemon & Pepper-, and Barbecue-flavored samples during two consumer studies (N = 115 each). Paprika- flavored CSC were excluded from Study 2 due to inferior acceptance and emotional ratings. CSC-elicited emotions were evaluated using a 25-term lexicon with CATA (Check-All-That-Apply) scaling (Study 1) and refined with an abbreviated lexicon containing food-evoked sensation-seeking emotions (5-point intensity scale). The two consumer studies differed in delivery format of product benefit information (a health/protein message and a food waste/sustainability message). Presenting two separate cues (Study 1) significantly increased overall liking (by 0.5 units) and PI (by 15%) for CSC compared to a single integrated message (Study 2), perhaps due to consumers' mode of information processing. Magnitude of increases was less for Barbeque CSC despite performing best overall (overall liking reaching 6.62 and PI reaching 61.7%). CSC generated mostly positive emotions, and informational cues increased sensation-seeking feelings, which can motivate trial of new foods. Accordingly, acceptance of CSC improved for 25 repeat-exposure consumers who participated in both Studies 1 and 2. In combination, sensory, cognitive, and emotional data showed favorable responses for flavored CSC as an appropriate application of this seafood byproduct.

Abstract
Edible insects recently gained attention as a potential contributor to the future sustainability of the food system. Insect farming has indeed shown to have environmental and nutritional benefits, but edible insects are still an unusual foodstuff in Europe. The purpose of this article is to analyze the barriers and drivers of insect consumption in Europe and to identify the most promising strategies to convince consumers to include insect-based products in their diets. To answer these research questions, a systematic review of the literature on the consumer's point of view about insects as food was performed. The results show that the main barrier to the development of this market is related to the psychological rejection of consumers induced by disgust toward entomophagy. To break down these barriers, it is essential to increase the general knowledge about the environmental and nutritional benefits of entomophagy. Furthermore, the limited size of the edible insect market appears to be a structural barrier. Expanding the reach of the market and consumer familiarity with edible insects will increase their acceptability. Finally, some product-related strategies are also highlighted. Furthermore, this article brings new knowledge about the effectiveness of the environmental motive in convincing consumers to try edible insects.

Abstract
This study examines the behavior and attitudes of adult Generation Z cohort members in relation to entomophagy. Specifically, it explores their familiarity with insect consumption, prior experience, and willingness to consume certain insect-based foods and drinks. Lastly, the Z cohort is segmented based on their behavior and attitudes. Through online quantitative research, a valid sample of 742 questionnaires was collected. Data analysis included descriptive statistics, reliability analysis, factor, hierarchical cluster, and K-means cluster analysis, as well as chi-square tests. Results revealed that 41.4% are familiar with what insect consumption is, and no one had previously engaged in entomophagy. The insect-based food that the Z cohort is most willing to try is bakery products containing insect flour. The 88.5% of the Z cohort is not willing to replace meat protein with insect protein, and 20.4% are interested in obtaining more information about entomophagy. Moreover, 6.3% of the Z cohort is "willing" to participate in sensory tests, but when contact information was requested, only one factual name with phone number was provided. Segmentation of the Z cohort's behavior was performed based on eight variables and four segments were identified: the "Future potential insect consumers" (29.1%), the "Rejecters" (26.7%), the "Disgusted, prefer to starve" (22.2%), and the "Inconsistent" (22.0%). Overall, the Z cohort is not food neophobic, but is unwilling to engage in entomophagy. Communication strategies are suggested to increase awareness and provide information about entomophagy and its benefits.

Abstract
Edible insects are recognized as a potential alternative and sustainable source of high-quality protein for the human diet. Entomophagy is highly related to negative emotions that may cause reluctance to adopt insects as food in Western countries. During human interaction, a person's facial emotional expression (FEE) may influence other people's emotional responses. A person's emotional state may affect his/her food preference and food choice. Understanding how other people's FEE would affect consumers' emotional profiles, liking, and subsequent willingness to try (WTT) and purchase intent (PI) toward insect-containing food products may help increase the acceptance of entomophagy. This study identified emotional responses toward chocolate chip cookies containing cricket protein using valence and arousal scales in order to explore the effects of other people's FEE (positive, negative, and/or sensation seeking) and to find the correlation between consumers' emotional and overall liking (OL) responses for cricket-containing chocolate chip cookies. Predicting PI for such cookies was also performed. For consumers who perceived positive emotion from other people's FEE after watching a short video clip, their emotional feeling was raised on both valence and arousal dimensions, while negative FEE stimulus imparted the opposite effects. The OL scores and emotional intensities after watching the three FEE videos were highly related to consumers' PI. Males compared to females rated the cricket-containing cookies higher on positive emotion intensity, OL, and PI. Among the three FEEs evaluated, the positive emotional stimulus would be beneficial in increasing acceptance, WTT, and PI of insect-containing foods. PRACTICAL APPLICATION: Edible insects are potentially alternative and sustainable sources of high-quality protein for the human diet. Entomophagy is highly related to negative emotions that cause reluctance to adopt insects as food in Western countries. Other people's facial emotional expressions (FEEs) may affect consumer food-evoked emotional profiles, overall liking (OL), and purchase intent (PI). For consumers who perceived positive emotion from other people's FEE, their emotional feeling was raised on both valence and arousal dimensions, and OL scores and emotion intensities were highly related to consumers' PI. Exploiting positive emotional stimuli as demonstrated in this study would be beneficial in increasing acceptance of insect-containing food.

Abstract
The interest in edible insects as food is growing, both in traditional and non-traditional insect-eating countries given their advantages in terms of sustainability and nutritional content. However, only a few studies have conducted cross-country investigations on the acceptance of including processed or whole insects in the diet. Thus, this study aimed to examine to which extent consumers were accepting (i) whole and visible mealworms, (ii) processed mealworms in their diet and (iii) to explore the factors affecting the acceptance level of consuming mealworms in countries with and without entomophagy tradition. An online survey was applied to collect responses (3,006) from five countries-i.e., Belgium, China, Italy, Mexico, and the US-using a quota sampling method. Moreover, an information treatment was included with about half of the participants receiving information about the advantages of edible insects as food (ingredient) and the presence of food safety regulations. Across countries, gender was the main factor affecting acceptance level as men accepted mealworms more than women. Entomophagy tradition mainly explained the differences among countries. Countries with entomophagy traditions (Mexico and China) showed higher acceptance of including whole or processed mealworms in the diet compared to countries with no entomophagy traditions (i.e., Belgium, Italy, and the US). While information and age did affect differently the acceptance of including processed mealworms in countries with entomophagy traditions showing that consumer acceptance was affected by information in Mexico and by age in China. Whereas it was found that younger people (below 42 years old) in countries without entomophagy tradition were more open to accepting processed mealworms in their diet. Moreover, across countries, the acceptance of including processed mealworms was higher compared to whole mealworms. These findings provide insights into which consumer segments to target and the potential impact of information when introducing new insect-based foods in countries with and without entomophagy traditions.

Abstract
Currently, insects are considered as a promising alternative protein source due to their nutritional content and their environmental sustainability. Notwithstanding this, generally consumers show reluctance towards the introduction of edible insects into their diet, mostly influenced by food neophobia. Persuasive communication strategies (e.g., informational vs. emotional appeals) have been a major topic in consumer behavior research. Scholars often refer to the construct of message sensation value (MSV), which is defined as the intensity of audio, visual, and content features of a message that elicit sensory, affective, and arousal responses. In this work, a computer-based experiment (N = 148) was conducted to investigate the effectiveness of messages based on different levels of MSV in promoting the intention to eat insect-based foods, and interactions between MSV and food neophobia. Results indicate that, MSV, food neophobia, and their interaction significantly affect the willingness to consume insect-based food products with or without visible insects, highlighting novel pathways for segmenting consumers, in order to strengthen the communication effects.

The Crick-Eatery: A Novel Approach to Evaluate Cricket ( Acheta domesticus) Powder Replacement in Food Products through Product Eating Experience and Emotional Response. Foods 2022; 11:foods11244115.

Abstract
This study was conducted to evaluate three different food products containing cricket powder for consumer acceptability, emotional response, satiety, and plate waste. US untrained consumers (n = 108), from the San Luis Obispo, CA area, were recruited to evaluate three food products (sausage, pasta, and brownies) as components in a three-course meal that either contain cricket powder (CP) or not (Control). The CP sausage was found to have lower liking scores than the Control for the attributes tested (p < 0.05). The CP pasta was found to be higher in overall liking than the Control (p < 0.05). The CP Brownies were rated highly across the attributes, except for texture and aftertaste (p < 0.05). Though the CP products were found to be as acceptable as the Controls, the use of cricket powder may have affected the texture and flavor profile of both the CP sausage and brownies. The participants selected more positive emotions terms for both the CP and Control products than negative emotions. Negative terms selected, such as worried, decreased once the products were consumed (p < 0.05). Plate waste and subjective satiety may also be indicators of consumer acceptability. Significant correlations were found between appearance liking and satiety as well as taste liking and plate waste for both the Control and CP products/dishes (p < 0.05). Based on this work, future acceptance of insect-based products may be encouraged by evaluating the products throughout an eating experience.

Abstract
In this study, an undervalued marine crustacean (Talitrus saltator) was characterized in terms of nutritional and heavy metal composition and its potential to affect human gut microbiota. Nutritional analysis of this crustacean revealed that it complies with the criteria established in European legislation to include nutritional claims in their labeling, such as "source of fiber," "low in fat," "low in sugars" and "high in protein." The analysis of the heavy metal content did not reveal any risk derived from the presence of Cd, Hg, or Pb, whereas essential metals contained in 100 g exceeded the minimum daily requirements recommended in Europe for Zn (19.78 mg/kg), Cu (2.28 mg/kg), and Fe (32.96 mg/kg). Using an in vitro system, the effect of T. saltator on the human colonic microbiota shows some beneficial effects, such as fermentation-maintained populations of Bifidobacterium or Lactobacillus, did not increase Firmicutes phylum counts, decreased the Firmicutes/Bacteroidetes ratio, and stimulated 11 metabolic pathways with respect to baseline. These results are unusual in a high protein content-food. However, negative effects were also found in gut microbiota relative proportions, such as an increase in the Proteobacteria phylum and especially some opportunistic bacteria from this phylum, probably due to the antimicrobial effect of chitin on other groups more sensitive to its effect. This work shows for the first time the effect of T. saltator on human colonic microbiota using and in vitro system. The presence of chitin in its composition could provide some beneficial effects by modulating the microbiota, but as T. saltator is a high-protein food, more studies should be carried out showing these benefits.

Abstract
Insect powders used in food products may lower the overall quality when compared to conventional counterparts. This preliminary study was used to develop and evaluate insect-based food products and to utilize them in a future consumer test. Pork sausage, dried pasta, and chocolate brownie formulations were developed to either contain NO cricket powder (Control) or have cricket powder (CP). The products were evaluated for proximate composition and product-dependent parameters. The protein content increased in the CP pasta and brownies (p < 0.05) while no changes were found in the sausage (p > 0.05). Fat content increased in both the CP pasta and brownies while it decreased in the CP sausage (p < 0.05). The CP sausage had a higher carbohydrate content than the Control (p < 0.05). Overall, this may be attributed to cricket powder being high in protein and fat while also containing dietary fiber. Cricket powder replacement may lead to noticeable color differences by increasing green and blue coloring in sausage and pasta (p < 0.05). Changes in textural properties (p < 0.05) may be attributed to cricket powder affecting protein solubility and emulsion stability in sausage while gluten formation may be interfered with in the brownies. Overall, cricket powder replacement had improved nutritional content with minor changes in quality parameters.

Abstract
The recent socio-economic situation requires producers to change the composition of basic foods. The aim of this study was to assess the technological properties of wheat flour enriched with cricket powder (CP) (at 5%, 10%, and 20% levels) for the development of bread and pasta. The hydration (i.e., water absorption capacity, oil absorption capacity, water absorption index, water solubility index, and swelling power), foaming (i.e., foaming capacity and stability),emulsifying (emulsifying activity and emulsion stability), and rheological (during gluten aggregation, mixing, extension, and leavening) properties were investigated. Finally, bread and fresh pasta were prepared and characterized. Emulsifying activity, stability, and foaming capacity decreased in the presence of CP, whereas foaming stability and water solubility increased. The results on dough rheology highlighted the need to increase the amount of water, and to decrease the mixing and leavening time, to keep an acceptable bread volume. Indeed, 10% CP enrichment led to a product characterized by a similar volume and crumb hardness to the control (wheat flour). Despite the decrease in extensibility caused by CP, it was possible to produce fresh pasta enriched with CP, with the best cooking behavior obtained at a 5% replacement level.

Abstract
The literature highlights the importance of insect consumption for nutritional health habits. The increasingly clear legislation, the developed studies demonstrating their nutritional value, and the prospect of overcoming some barriers that have prevented consumers from consuming insects are among the reasons supporting the advantages of consuming insects. The leading determinants of consumption are culture and individual and social beliefs, accessibility to a particular nutritional resource, and individual behavior. The barriers to neophobia were analyzed by evaluating factors of influence and their respective relationship and meaning through quantitative research to measure the significance of the results. To develop a conceptual model that aims to change eating behavior and recognize structural aspects that can be barriers in the process of changing eating behavior, a methodological framework was developed. The methodological framework aimed to identify the characteristics that can be associated with the profile of opinion leaders, and it included a questionnaire which was applied to 213 young people. Moreover, the structural equation model was the statistical technique used. Given the projected population growth and increasing life expectancy, nutrition is a challenge in terms of health, but also in economic, social, and environmental respects. Aiming for sustainability, it is crucial to identify nutritional alternatives within the circular economy.

Abstract
This paper aims to model consumers’ perceptions and preferences toward alternative foods. We conducted a survey of 519 people and analyzed their responses using a structural equation model. The article discusses the role of food innovation quality (FIQ), a concept developed from innovative design, which shows how consumers perceive the quality of products in an innovative context. Further, the paper discusses the relationship between this concept and promoting consumer acceptance of alternative foods. Studies suggest that higher FIQ may lead to increased consumer satisfaction with alternative foods, which may in turn lead to higher levels of trust and continuation. Moreover, expectations play a significant role in FIQ and in the perceived value of alternative foods in the model. This illustrates that the promotion of alternative foods in an innovative manner should include establishing a practical mechanism for meeting consumer expectations. Given the continued growth in global food demand, it is both effective and beneficial to promote alternative foods through innovative design as part of a broader food industry approach. On the one hand, alternative foods produced in an innovative manner serve to energize the consumer market by expanding dietary choices. On the other hand, alternative foods, which include new forms of meat products, contribute to the alleviation of the problem of meat production capacity in agriculture. In addition, the alternative foods process eliminates the emission of large amounts of carbon dioxide by traditional agriculture, increasing the sustainability of food production.

Abstract
Insects are gaining more and more space in food and feed sectors, creating an intense scientific interest towards insects as food ingredients. Several papers deal with cereal-based products complemented by insect powder in the past few years. However, adulteration and quality control of such products present some hot topics for researchers, e.g., how can we justify the amounts and/or species of the insects used in the given products? Our paper aims to answer such questions by analysing seven edible insect powders of different species independently. The mixtures with wheat flour were analysed using near infrared spectroscopy and chemometric methods. Not only powders of different species were clearly differentiated, but also mixtures created by different amounts of wheat flour. Prediction of insect content showed 0.65% cross-validated error. The proposed methodology gives an excellent tool for quality control of insect-based cereal food products.

Effects of Catfish (Ictalurus punctatus) Bone Powder on Consumers’ Liking, Emotions, and Purchase Intent of Fried Catfish Strips. Foods 2022; 11:foods11040540.

Abstract
Catfish are the predominant U.S. aquacultural product. However, byproducts from filleting, including bones that are high in calcium, typically go to waste or are sold as a low-valued feed. This research evaluated the potential use of catfish bone powder (CBP; 21.07% calcium) as a food ingredient. Catfish fillet strips were dredged with a breading mix (CBPM) containing 0% (0CBPM), 10% (10CBPM), and 20% (20CBPM) CBP before frying. Consumers (N = 211) evaluated sensory liking (nine-point hedonic scale) and attribute intensity (JAR scale), emotions (check-all-that-apply), and purchase intent (PI, yes/no) of samples. Color and texture were measured instrumentally. CBP did not show any negative effects on liking scores, although crispiness was scored higher for 20CBPM (mean = 6.88) than 10CBPM (mean = 6.43). Positive emotions were most relevant to CBP-containing samples, with significantly higher rates of adventurous and understanding. Information about calcium fortification using CBP increased PI to 81.04% for the 10CBPM and 83.89% for the 20CBPM samples and showed a greater effect on Latin Americans/Hispanics than U.S. Americans. Consumers were not averse to the consumption of CBP which can contribute to sustainable nutrition through waste reduction. Successful calcium fortification of fried catfish dredged with 20% CBP did not compromise sensory liking and may be feasible in other products.

Abstract
Insects may potentially provide an alternative protein source. However, consumers may not easily accept insects due to feelings of disgust. Therefore, identifying early adopters of insect-based food products may determine their future acceptance. This study was conducted to (1) identify early adopter Mind-Sets of insect-based food products, (2) determine product features early adopters would prefer in an insect-based food product, and (3) determine differences in Mind-Sets in different countries. Two studies were distributed online in the US and the Philippines. The first study included information about insects, while the second study had no information on insects. The experimental design included elements, or product features, regarding insect-based products that participants evaluated. Preference Analysis was used to segment the participants into Mind-Sets. Based on the results, participants neither liked nor disliked the elements used. Participants in the studies without insect information were found to have higher liking when comparing liking. Participants who were aware of the study being about insects may have had less interest when evaluating the elements, as the response times between the US studies were significantly different (p < 0.05). The role of information and segmentation of the participants demonstrates the importance of experimental design when using Preference Analysis.

Abstract
Sustainable and nutritious alternatives are needed to feed the ever-increasing world population. The successful incorporation of edible-cricket protein (ECP) into foods needs deeper consumer insights. Treatments (plain, Italian, and Cajun pita chips containing 6.9% w/w ECP) were evaluated by subjects for overall liking (OL), emotions, and purchase intent (PI) in three different moments: (1) before tasting, (2) after tasting/before ECP statement, and (3) after tasting/after ECP statement. Attributes’ liking scores were evaluated only after tasting/before ECP statement. Liking scores (mixed-effects ANOVA), emotions, and PI across moments within treatments/across treatments within moments were evaluated. Emotion-based penalty-lift analyses for OL within moments were assessed using two-sample t-tests (p < 0.05). Random forest model analyzed after-tasting informed PI and variables’ importance. Although formulations’ OL and PI were similar across moments, plain and Italian chips had higher after-tasting (before and after ECP statement) OL than the Cajun chips. Moments indirectly affected OL via emotions elicitation. Valence and activation/arousal emotions discriminated across moments for the plain treatment whereas valence and mostly activation/arousal terms discriminated across moments for the Italian and Cajun treatments, respectively. For either formulation or moment, “interested” and “adventurous” positively affected OL. Before and after-tasting attribute liking, “satisfied,” and “enthusiastic” emotions were critical in predicting after-tasting informed PI.

Abstract
The link between coffee aroma/flavor and elicited emotions remains underexplored. This research identified key sensory characteristics of brewed black coffee that affected acceptance, purchase intent and emotions for Thai consumers. Eight Arabica coffee samples were evaluated by eight trained descriptive panelists for intensities of 26 sensory attributes and by 100 brewed black coffee users for acceptance, purchase intent and emotions. Results showed that the samples exhibited a wide range of sensory characteristics, and large differences were mainly described by the attributes coffee identity (coffee ID), roasted, bitter taste, balance/blended and fullness. Differences also existed among the samples for overall liking, purchase intent and most emotion terms. Partial least square regression analysis revealed that liking, purchase intent and positive emotions, such as active, alert, awake, energetic, enthusiastic, feel good, happy, jump start, impressed, pleased, refreshed and vigorous were driven by coffee ID, roasted, ashy, pipe tobacco, bitter taste, rubber, overall sweet, balanced/blended, fullness and longevity. Contrarily, sour aromatic, sour taste, fruity, woody, musty/earthy, musty/dusty and molasses decreased liking, purchase intent and positive emotions, and stimulated negative emotions, such as disappointed, grouchy and unfulfilled. This information could be useful for creating or modifying the sensory profile of brewed black coffee to increase consumer acceptance.

Abstract
Simple Summary In this study, the relationship of a sustainable diet and insect consumption is refined. The main objective is to analyse consumer perception of food sustainability and attitudes towards food consumption and the effect on the environment and their willingness to include insects as a sustainable solution to reduce meat consumption in their diet. These results provide important insights to guide consumers to consider the use of food alternatives and for policy makers. Targeting the right consumers is necessary to create a market for insect-based food. This research contributes to addressing global food security and sustainability through raising the awareness of the benefits of insects as food in the consumers’ minds. Recommendations are included to improve the communication of the advantages of this food type. Abstract The main objective of this research paper is to understand consumer knowledge and perception of insects for food. Primary data was collected using a questionnaire conducted in Rome, and the data was analysed using a probit model in order to understand consumers’ attitudes to include insects as a sustainable solution to meat consumption in their diet. We connected the participants with a willingness to consume insects with those that are critical, informed, and concerned about the environment. This study shows that insects’ consumption and social acceptance is very low even for people who have a greater sensitivity to sustainable diets. Suggestions are included to improve the communication of this food type to raise awareness in the consumers’ minds. This research continues the debate on sustainability and global food security.

Effect of Disclosed Information on Product Liking, Emotional Profile, and Purchase Intent: A Case of Chocolate Brownies Containing Edible-Cricket Protein. Foods 2021; 10:foods10081769. [PMID: 34441546 PMCID: PMC8393427 DOI: 10.3390/foods10081769] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Revised: 07/27/2021] [Accepted: 07/28/2021] [Indexed: 01/26/2023] Open
Abstract
Edible insects, a sustainable and nutritious alternative to conventionally derived proteins, are unfamiliar to Westerners and often associated with negative sentiments. Edible-cricket protein (ECP) added to chocolate brownies (CB) [0% ECP = CBWO (without) vs. 6% w/w ECP = CBW (with)], and disclosed information [no ECP added = (−) vs. ECP with benefits = (+), ECP− and ECP+, respectively] yielded four CB treatments (CBWO−, CBWO+, CBW−, and CBW+). Subjects (n = 112 female and n = 98 male) rated liking, selected emotions before- and after-tasting, and determined consumption (CI) and purchase intent (PI) after tasting. Likings were analyzed with mixed-effects ANOVA and post hoc Tukey’s HSD test. Emotions were evaluated with Cochran’s-Q test and correspondence analysis. Emotions driving or inhibiting overall liking (OL) were assessed with penalty-lift analyses using two-sample t-tests. A random forest algorithm was used to predict PI and estimate variables’ importance. Female’s and male’s expected OL were higher for CBWO− than for CBWO+. Females’ actual OL was higher for CBWO than for CBW regardless of the disclosed information but males’ actual OL was the same across treatments. Females exhibited negative-liking disconfirmation for CBW−. In both tasting conditions, the disclosed information affected treatments’ emotional profiles more than formulation. After-tasting emotions “happy” and “satisfied” were critical predictors of PI.

Foods 2021; 10:foods10071480. [PMID: 34202263 PMCID: PMC8306907 DOI: 10.3390/foods10071480] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2021] [Revised: 06/14/2021] [Accepted: 06/21/2021] [Indexed: 11/16/2022] Open
Abstract
Currently, many consumers are reluctant to consume edible-cricket protein (ECP). Chocolate brownie (CB) formulations without (WO) and with (W) 6%w/w ECP (CBWO and CBW, respectively) were presented under two informed conditions: formulated without ECP (ECP-) and formulated with ECP+benefits (ECP+). CBWO- (CBWO presented with the "ECP-" claim), CBWO+ (CBWO presented with the "ECP+" claim), CBW- (CBW presented with the "ECP-" claim), and CBW+ (CBW presented with the "ECP+" claim) were evaluated by 210 consumers for expected and actual attribute liking, and after-tasting consumption and purchase intent. Multi-way ANOVA, principal component analysis, and agglomerative clustering examined liking. Cochran-Q tests compared actual-liking profiles, purchase and consumption intent. Before tasting, CBW- obtained the lowest appearance liking, flavor liking was higher for ECP- than for ECP+ for either formulation, and ECP+ decreased aroma and overall liking only for CBWO. After tasting, CBWO had higher liking than CBW (except for aroma) for either informed condition. Regardless of the formulation, ECP- and ECP+ had similar actual liking. Nevertheless, ECP+ prevented negative disconfirmation for both formulations while ECP- decreased texture liking (for CBWO) and all liking (for CBW) upon tasting. Females' consumption intent was higher for CBWO regardless of the informed condition, but CBW+ achieved a similar purchase intent to CBWO- for both genders.
