Nutritional Profiles of Non-Dairy Plant-Based Cheese Alternatives

Oleogelation for saturated fat replacement in vegan cheese

Oleogelation was investigated to reduce the saturated fat content of vegan cheese. Oleogels were formulated using a range of oleogelators, oleogelator concentrations and oil phase compositions to study the effect that adjusting these parameters had on both oleogel and vegan cheese properties. Comparing oleogels at an equivalent mass basis of 20 wt%, phytosterol oleogels exhibited greater hardness (5.9 N) than either monoglyceride (1.7 N), stearic acid (0.7 N) or carnauba wax (4.3 N) oleogels. Oleogels generally exhibited lower oxidative stability than the coconut and sunflower oil controls, with phytosterol oleogelators exhibiting a pro-oxidant effect. Oleogel-based vegan cheese properties were highly tuneable, with hardness and adhesiveness levels which could be in excess or below that of the control samples. Furthermore, oleogelled vegan cheese samples exhibited superior meltability whilst offering major reductions in saturated fat content from 28 % in the control to as low as 2 % in oleogel-based vegan cheese samples.

Application of Nordic Keyhole and Nutri-Score for assessment of nutritional quality of plant-based dairy analogues

BACKGROUND

Public interest in plant-based dairy analogues is increasing; thus, their assessment by front-of-pack nutrition labelling schemes such as Keyhole and Nutri-Score can facilitate the identification of products with optimal nutritional quality. In this study, Keyhole and the latest version of Nutri-Score criteria were applied to plant-based dairy analogues (i.e., milk, yoghurt, cheese, cream, fat spread, and ice cream analogues) in the Swedish market to evaluate their nutritional quality.

METHODS

Nutritional data for 222 plant-based dairy analogues were collected from food manufacturers' websites, and the eligibility of these analogues for Keyhole and Nutri-Score (A to E) were assessed. Products eligible for Keyhole and Nutri-Score A or B were deemed to have optimal nutritional quality.

RESULTS

16% of plant-based milk analogues (from oat-, almond-, rice-, and potato-based products), 2% of plant-based yoghurt analogues and 37% of plant-based fat spread analogues were eligible for Keyhole. The plant-based cheese, cream and ice cream analogues were ineligible for Keyhole. None of the plant-based milk analogues qualified for Nutri-Score A, and 45% (mainly soy-, almond-, coconut-, pea- and mixed-based products) qualified for Nutri-Score B. 68% of plant-based yoghurt analogues (from oat-, soy-, almond- and mixed-based products) qualified for Nutri-Score A or B. The plant-based cheese, fat spread and ice cream analogues were ineligible for Nutri-Score A or B and 32% of plant-based cream analogues qualified for Nutri-Score B. A higher percentage of organic milk analogues and a lower percentage of organic yoghurt analogues were eligible for Keyhole and Nutri-Score A or B compared to their non-organic varieties. Keyhole and Nutri-Score had an agreement on classifying two plant-based dairy analogues as optimal nutritional quality products and 133 plant-based dairy analogues as suboptimal.

CONCLUSIONS

There is variability in the eligibility of plant-based dairy analogues for Keyhole and Nutri-Score labelling. Eligibility for Keyhole was highest among plant-based fat spread analogues, while Nutri-Score A and B ratings were more common for plant-based yoghurt analogues. Plant-based cheese and ice cream analogues were ineligible for Keyhole and Nutri-Score A or B. Since the micronutrient content of organic and non-organic plant-based dairy analogues did not affect their evaluation by Keyhole and Nutri-Score, this limitation warrants further consideration.

Plant tissue-based scaffolds filled with oil function as adipose tissue mimetics

Cellulosic scaffolds filled with oil were designed to replicate animal adipose tissues. Many plants are structured as polysaccharide-based cellular solids. They maintain their integrity after drying, can serve as a scaffold for incorporating fat, and do not lose integrity upon heating, thus resembling native adipose tissue. Carrots, broccoli, and asparagus were freeze-dried and subsequently filled with peanut oil, its glycerolysis product (GP), and the oleogel of this GP. Oleogel-filled scaffolds displayed high oil binding capacity (≥95%), and an oil loss resembling that of adipose tissue. In addition, the texture of oleogel-filled asparagus and broccoli tissue closely resembled that of beef and pork adipose tissues, respectively. Plant scaffolds closely emulated the temperature-dependent rheological behavior of adipose tissue. These new materials could significantly improve the quality of plant-based meat analogues, such as burgers and sausages, by preventing the thermal softening of the material upon cooking and excessive oil loss.

Insight into the potato protein-based vegan cheese: A comprehensive study on physicochemical, mechanical and molecular properties

The growing interest in plant-based diets is driving the search for new products, including alternatives to dairy cheese. The aim of this research was to develop a recipe and technology for the production of a vegan cheese, then to characterize the physical, mechanical as well as molecular properties of the obtained products. The use of protein isolated from potato juice seems to be appropriate due to the nutritional value of the formed product and to the environmental benefits, that is, the use of waste potato juice to obtain a valuable raw material. It was found that as a result of the interaction of protein with carbohydrates and fats, the hardness and viscosity of the obtained products increase. Moreover, it was shown that one of the tested cheese analogues, which contains 5% of potato juice protein, 12% of oil and 25% of modified potato starch, is the optimal analyzed variant. It has attractive culinary properties, such as meltability; therefore, it can be used in production of hot dishes, for example, as a plant-based alternative to dairy cheese in pizza.

Consumer Expectations for Cream Cheese: A Category Appraisal Study in the United Kingdom with Dairy and Plant-Based Variants in Various Flavours

The purpose of the present research was to deliver new knowledge of consumer expectations for plant-based (PB) alternatives to cream cheese (PBCCA) by conducting a category appraisal study. Around 1100 consumers from the United Kingdom (UK) who followed omnivore and flexitarian diets participated in an online survey. They evaluated 13 written stimuli presented as product names encompassing dairy cream cheese and PBCCAs in different flavours (original/natural, garlic/herb, salmon, strawberry, chocolate) and different product formulations (low-fat, lactose-free). A multi-response approach was used that obtained sensory, emotional, conceptual, and versatility product evaluations. The research findings, which matched predictions, showed: (1) negative product expectations for PBCCAs replicated across flavour variants, providing evidence of a systematic PB effect relative to cream cheese; (2) sensory and non-sensory drivers of expected product liking resembled those established for the cream cheese category with actual product experience; (3) sensory and non-sensory drivers of expected product versatility strongly resembled those of expected product liking; (4) groups of consumers existed with different preferences, including flavour and product type preferences (dairy, PBCCA); and (5) negative product expectations for PBCCAs translated to a stated behavioural preference for cream cheese over PBCCA, and dairy-based samples were chosen over their PB counterparts regardless of flavour. The category appraisal approach confirmed the systematic negative appeal of PBCCAs relative to their dairy counterparts. This was in line with findings from past research on other PB alternative foods and invites a rethinking of the appeal of this class of products to participants in this research, who represent a large segment of UK consumers.

Plant-based cheese analogs: structure, texture, and functionality

Plant-based cheese analogs have been developed using plant-based ingredients to mimic the appearance, structure, and flavor of conventional cheeses. Due to the complex composition and structure of cheese, developing plant-based cheese analogs that completely replicate its physicochemical, structural, sensory, and nutritional features is a highly challenging endeavor. Therefore, the design of the structure of plant-based cheese analogs requires a critical evaluation of the functional features of the selected ingredients and the specialized combination of these ingredients to create a desired structure. This review provides a comprehensive understanding of the structure, texture, and functionality of plant-based cheese analogs, covering the formulation and the characteristic properties of the end-use product, such as rheological behavior and microstructural properties, as well as tribology perspectives. Subsequently, the melting and stretchability characteristics of these products have been assessed to comprehend the response of plant-based cheese substitutes when subjected to heat.

Consumer evaluations of commercially available plant-based cheddar cheese alternatives reveal inferior taste, nutrition and emotional appeal

Many people in the Western world wish to reduce dietary reliance on animal-based and animal-derived foods. Plant-based (PB) meat and dairy alternatives can aid in this transition, but in the dairy category, only the milk market is well developed. Attention in the present research is, therefore, directed to PB cheese alternatives (PBCA), which were studied relative to dairy cheeses in a consumer taste test (central location setting) with 157 New Zealand (NZ) consumers conducted in 2023. Five commercial semi-hard cheeses from cow's milk and three commercial PBCAs in the cheddar style were tested. All samples were presented blind, and a multi-response measurement paradigm (hedonic, sensory, emotional, conceptual, situational, attitudinal) was used. Results showed that, without major exception, all PBCAs had lower liking ratings, inferior sensory, emotional and conceptual characterisations and poorer attitudinal and situational use evaluations than their dairy counterparts. Further, all of the PBCAs were rated similarly, as contrasted with the dairy cheese samples, which were differentiated based on textural and flavour attributes, liking and non-sensory characterisations. It was concluded that, as a whole, PBCAs in the 2023 NZ market were poorly accepted by consumers, suggesting that much more research and consumer-focused product development is needed before these products offer consumers suitable choices if they seek to transition from an animal-based to a PB diet.

Analysis of physicochemical properties of nut-based milk and sweetened condensed milk alternatives

This study analyzed the physicochemical properties of nut-based milk and sweetened condensed milk (SCM) alternatives. Four types of nuts (almonds, cashews, hazelnuts, and walnuts) were roasted at 140 °C for 15 min, followed by the preparation and analysis of milk and SCM alternatives. During the production of SCM by heating with adding sugar, the pH, moisture, and L* decreased, while the carbohydrates, viscosity, and browning index increased significantly (p < 0.05). Oleic acid, linoleic acid, and linolenic acid contents were comparable among all samples (p > 0.05). Volatile compounds were analyzed using HS-SPME-GC-MS to determine changes due to roasting and heating, and a total of 54 volatile compounds were identified. These findings to show the importance of the physicochemical characteristics of milk and SCM alternatives, provide practical information for the development of improved-quality dairy alternatives.

Nutritional analysis of vegan recipes: From social media to plate

The study aimed to determine the nutritional composition of vegan recipes shared on the Instagram social media platform and to compare these ingredients with their non-vegan/omnivorous versions. Turkish and English vegan recipes of meatballs (n = 53), burgers (n = 12), pizza (n = 15), pasta (n = 38), cake (n = 58), and cookies (n = 52) were obtained from Instagram. They all met the criteria of being shared as #vegan labeled, presented detailed information about ingredients, and only included plant-based ingredients. Afterward, non-vegan/omnivorous recipes (n = 228) were determined as equivalent to the vegan recipes in each food group, and a total of 456 recipes were evaluated. The amounts of macro- and micronutrients per 100-gram serving were obtained by the Nutritional Data System (BeBiS). According to the outcomes, the most significant differences in nutritional composition were found between vegan and non-vegan meatball recipes. The levels of cholesterol and B12 were significantly lower in English vegan recipes of meatballs, pasta, cake, and cookies compared to their non-vegan versions (p < .05). Consuming different vegan foods throughout the day could provide complementary nutrient intake and sustainable optimal health. Nevertheless, recipe-based updates could be an innovative approach in future vegan studies. In addition, analysis of vegan recipes could be considered to modulate vegan supplementation programs.

Opinion Piece: New Plant-Based Food Products Between Technology and Physiology

The rapid growth of product sectors for plant-based meat and dairy alternatives has raised significant scientific interest in their nutritional and ecological benefits. Here, it outlines the fractionation of plant-based raw materials and describes the technologies applied in the production of meat and dairy substitutes. Moreover, the study describes the effects of these new products on human nutrient supply and metabolic responses. Examples of meat-like products produced by extrusion technology and dairy alternatives are provided, addressing production challenges and the effects of processing on nutrient digestibility and bioavailability. In contrast to animal-based products, plant-based protein ingredients can contain many compounds produced by plants for defense or symbiotic interactions, such as lectins, phytates, and a wide range of secondary metabolites. The intake of these compounds as part of a plant-based diet can influence the digestion, bioaccessibility, and bioavailability of essential nutrients such as minerals and trace elements but also of amino acids. This is a critical factor, especially in regions with limited plant species for human consumption and inadequate technologies to eliminate these compounds. To fully understand these impacts and ensure that plant-based diets meet human nutritional needs, well-controlled human studies are needed.

Nutritional and microbial profiles of ripened plant-based cheese analogs collected from the European market

Plant-based cheese analogs have emerged as a novel global market trend driven by sustainability concerns for our planet. This study examines eleven soft ripened plant-based cheese analogs produced in Europe, primarily with bloomy rinds and cashew nuts as the main ingredient. First, we focused on exploring the macronutrients and salt content stated on the labels, as well a detailed fatty acid analysis of the samples. Compared to dairy cheeses, plant-based cheeses share similarities in lipid content, but their fatty acid profiles diverge significantly, with higher ratio of mono- and polyunsaturated fatty acids such as oleic and linoleic acids. We also investigated the microbiota of these analog products, employing a culture-dependent and -independent approaches. We identified a variety of microorganisms in the plant-based cheeses, with Lactococcus lactis and Leuconostoc mesenteroides being the dominant bacterial species, and Geotrichum candidum and Penicillium camemberti the dominant fungal species. Most of the species characterized are similar to those present in dairy cheeses, suggesting that they have been inoculated as culture starters to contribute to the sensorial acceptance of plant-based cheeses. However, we also identify several species that are possibly intrinsic to plant matrices or originate from the production environment, such as Pediococcus pentosaceus and Enterococcus spp. This coexistence of typical dairy-associated organisms with plant associated species highlights the potential microbial dynamics inherent in the production of plant-based cheese. These findings will contribute to a better understanding of plant-based cheese alternatives, enable the development of sustainable products, and pave the way for future research exploring the use of plant-based substrates in the production of cheese analogues.

Think and Choose! The Dual Impact of Label Information and Consumer Attitudes on the Choice of a Plant-Based Analog

This study explored the impact of various label information (extrinsic attributes) and sociodemographic and attitudinal factors (intrinsic attributes) on Brazilian consumer choices, using simulated traditional and plant-based muçarela cheese as the model product. The research was conducted in two phases: the first involved a structured questionnaire assessing attitudinal dimensions such as Health Consciousness, Climate Change, Plant-based Diets, and Food Neophobia, along with sociodemographic data collection. The second phase comprised a discrete choice experiment with (n = 52) and without (n = 509) eye tracking. The term "Cheese" on labels increased choice probability by 7.6% in a general survey and 15.1% in an eye tracking study. A prolonged gaze at "Cheese" did not affect choice, while more views of "Plant-based product" slightly raised choice likelihood by 2.5%. Repeatedly revisiting these terms reduced the choice probability by 3.7% for "Cheese" and 1% for "Plant-based product". Nutritional claims like "Source of Vitamins B6 and B12" and "Source of Proteins and Calcium" boosted choice probabilities by 4.97% and 5.69% in the general and 8.4% and 6.9% in the eye-tracking experiment, respectively. Conversely, front-of-package labeling indicating high undesirable nutrient content decreased choice by 13% for magnifying presentations and 15.6% for text. In a plant-based subsample, higher environmental concerns and openness to plant-based diets increased choice probabilities by 5.31% and 5.1%, respectively. These results highlight the complex dynamics between label information, consumer understanding, and decision-making.

Industrially Produced Plant-Based Food Products: Nutritional Value and Degree of Processing

The plant-based food market is rapidly growing, offering innovative options to meet consumer expectations. However, a comprehensive analysis of the nutritional quality of these foods is lacking. We aimed to characterize industrial plant-based food products' nutritional value and degree of processing. A cross-sectional study was conducted on two market-leading Portuguese food retail chains by assessing the nutritional composition of all the available pre-packaged plant-based food products (n = 407). These products were categorized into meal alternatives, dairy alternatives, and other products containing dairy/meat alternative ingredients including ready meals and desserts. The products' nutritional quality was assessed according to the cut-offs established by the Portuguese Directorate General of Health [DGS] on total fat, saturated fat, sugar, and salt, and considering the degree of processing using NOVA classification. One-tenth of the products were classified as having a high total fat, saturated fat, sugars, or salt content. In some sub-categories, half of foods were classified as high in saturated fat, and over two-thirds were considered high salt products. Less than one-third exhibit a good nutritional profile based on the national cut-offs. A total of 84.3% of plant-based food products were ultra-processed. These findings emphasize the need to improve the nutritional profile of plant-based options.

Next-Generation Plant-Based Foods: Challenges and Opportunities

Owing to environmental, ethical, health, and safety concerns, there has been considerable interest in replacing traditional animal-sourced foods like meat, seafood, egg, and dairy products with next-generation plant-based analogs that accurately mimic their properties. Numerous plant-based foods have already been successfully introduced to the market, but there are still several challenges that must be overcome before they are adopted by more consumers. In this article, we review the current status of the science behind the development of next-generation plant-based foods and highlight areas where further research is needed to improve their quality, increase their variety, and reduce their cost, including improving ingredient performance, developing innovative processing methods, establishing structure-function relationships, and improving nutritional profiles.

Comparison of Physical and Compositional Attributes between Commercial Plant-Based and Dairy Yogurts

A primary strategy led by the food industry to improve the sustainability of the agricultural food supply is the development of modern plant-based alternatives. The information provided via marketing and product packaging provides consumers with the expectation that these products provide a similar product experience to conventional products, yet it is not well understood whether these commercial alternative products are comparable to traditional animal-based products. To aid in developing improved plant-based products, this study aimed to compare the quality and physical attributes of commercially available plant-based and dairy yogurts. Using instrumental methods, commercially available yogurt products were analyzed for their pH, titratable acidity, color, water activity, moisture content, and rheology, which included 13 plant-based (almond, cashew, coconut, oat, soy) and 8 whole-milk dairy yogurts. The present study reveals that the plant-based and dairy yogurts had no significant differences in pH, lactic acid, water activity, or moisture content. However, there were significant differences in the color and texture properties between the plant-based and dairy yogurts. Additionally, significant differences were observed across the plant-based yogurt products in terms of their color and texture properties. This highlights the need for additional studies to determine how individual ingredients influence the physical characteristics and textural properties to direct the development of plant-based yogurts. Improving upon the physicochemical properties of plant-based yogurt may encourage more consumers to adopt a more sustainable diet.

Nutritional profile of plant-based dairy alternatives in the Swedish market

The market for plant-based dairy alternatives is growing; therefore, focusing on the nutritional quality of these products is important. This study evaluates the nutritional profile of plant-based alternatives to milk, yoghurt, cheese, cream, ice cream and fat spread in the Swedish market and compares them to corresponding dairy products. The nutritional quality of organic vs non-organic and plain vs flavoured plant-based milk and yoghurt alternatives was also assessed. Nutritional data for 222 plant-based dairy alternatives were collected from the manufacturers' websites, and data for corresponding dairy products were obtained from the Swedish Food Composition Database. Plant-based dairy alternatives had higher fibre content than dairy products, while their protein content was lower, except for soy-based products. The saturated fat content of plant-based dairy alternatives was similar to or lower than dairy products, except for coconut-based yoghurt and plant-fat-based cheese. Their energy content was also similar to or lower than dairy products, except for coconut-based yoghurt, plant-based fat spread and plant-based ice cream, which contained higher energy than yoghurt, blended margarine, and ice cream, respectively. The micronutrient fortification was mainly in plant-based milk, yoghurt, and cheese alternatives; thus, compared to dairy, they had similar or higher vitamins D, B2, and B12 (except in plant-based milk alternatives), calcium and iodine content. Furthermore, organic plant-based milk and yoghurt alternatives had a lower micronutrient content (e.g., vitamins B2 and B12, iodine and calcium) except for vitamin D than non-organic varieties. Flavoured plant-based milk and yoghurt alternatives were higher in energy and total sugar than plain varieties. In summary, plant-based dairy alternatives have nutritional strengths and weaknesses compared to dairy products that should be considered when replacing dairy.

Plant-Based Alternatives Need Not Be Inferior: Findings from a Sensory and Consumer Research Case Study with Cream Cheese

Reliance on animal foods must be reduced to improve planetary and human well-being. This research studied plant-based cheese alternatives (PBCA) relative to dairy cheese in a consumer taste test with 157 consumers in New Zealand. A case study approach used cream cheese (commercially available) as the focal product category (2 PBCA, 2 dairy) and implemented a multi-response paradigm (hedonic, sensory, emotional, conceptual, situational). "Beyond liking" insights were established, including drivers of liking (sensory, non-sensory) and sensory drivers of non-sensory product associations. Two consumer segments were identified, of which the largest (n = 111) liked PBCA and dairy samples equally (6.5-6.7 of 9). In this PBCA Likers cluster, the key sensory drivers of liking were 'creamy/smooth mouthfeel', 'dissolves quickly in mouth', and 'sweet', while a significant penalty was associated with 'mild/bland flavour'. The non-sensory data contributed additional consumer insights, including the four samples being perceived as differently appropriate for 9 of 12 use situations, with PBCA being regarded as less appropriate. In the limited confines of this case on cream cheese, the findings show that PBCA need not be inferior to their dairy counterparts despite a general narrative to the contrary. Of note, the results were obtained among participants who were open to eating a more PB diet but were not vegetarian or vegan.

Replacement of Milk and Dairy Products with Soy-Based Alternatives-How to Avoid Nutrient Deficiencies in a Milk-Free Diet?

BACKGROUND

In Germany, milk and dairy products are increasingly replaced by their plant-based alternatives. Although they can be used as substitutes, they differ significantly in their nutrient composition; thus, substitution could lead to nutrient deficiencies. So far, there are no food-based dietary recommendations that show which foods can replace milk and dairy products in a healthy way when switching to a plant-based substitute.

OBJECTIVES

Against this background, the question arises as to how to ensure adequate intake of critical nutrients when plant-based alternatives are consumed instead of milk and dairy products. To answer this question, this study aims to analyze what dietary changes would be required to avoid possible nutrient deficiencies and what types of foods can be consumed instead.

METHODS

To answer the research question, 3 different models are compared using the linear programming method: healthy diets with 1) milk and dairy products, 2) nonfortified plant-based alternatives, and 3) fortified plant-based alternatives. The models are applied to omnivorous, pescatarian, and vegetarian diet types.

RESULTS

The results show that when consuming nonfortified soy alternatives, an adequate supply of calcium and, in the case of a vegetarian diet, vitamin B12 can only be achieved if significant dietary changes are made compared to the average diet. This includes a significantly higher consumption of fruit and vegetables, whereby within the groups, calcium-rich varieties should be chosen (e.g., green leafy vegetables). When consuming fortified soy-based alternatives instead, the absence of milk and dairy products can be well compensated by the nutrients currently added to commercially available products.

CONCLUSIONS

Given the trend to consume less milk and dairy products or to abstain from them altogether, public health measures should point out possible nutrient deficiencies as well as necessary dietary changes, especially because in Germany, many plant-based alternatives are not fortified.

Nutritional and health benefits and risks of plant-based substitute foods

Plant-based substitutes (PBS) are seen as a convenient way to transition to a more plant-based diet, but their potential health benefits and nutritional concerns remain debated. Based on a review of the literature, it is concluded here that the primary risk of insufficient nutrient intake with PBS concerns iron and calcium, which are critical to the nutritional value of PBS. Other risks were identified but these would depend on the characteristics of the overall diet, as is the case for iodine in a diet containing no seafood or dairy, and vitamin B12 in a vegetarian/vegan diet. Conversely, the use of PBS is also expected to confer some benefits for long-term health because it would result in higher fibre intakes (in the case of meat PBS) and lower SFA intakes (but higher PUFA/MUFA intakes), but attention should be paid to a potential increase in sodium intake with PBS of meat products. In fact, a recurring finding in this review was that PBS is a very heterogeneous food category involving considerable variations in ingredient and nutrient composition, and whose design could be improved in order to foster nutritional and health benefits. The latter also depend on the animal food that is being replaced and are only deemed likely when PBS replace red meat. The fortification of PBS with key nutrients such as iron and calcium may constitute an actionable public health solution to further shift the balance in favour of PBS in the context of the current dietary transition in western countries.

Comprehensive quality evaluation of plant-based cheese analogues

BACKGROUND

In recent years, there has been an increasing demand for plant-based cheese analogues, however, the protein content of plant-based cheeses currently on the market is generally low and cannot meet the nutritional needs of consumers.

RESULTS

Based on the ideal value similarity method (TOPSIS) analysis the best recipe for plant-based cheese was 15% tapioca starch, 20% soy protein isolate, 7% gelatine as a quality enhancer and 15% coconut oil. The protein content of this plant-based cheese was170.1 g kg-1 , which was close to commercial dairy-based cheese and significantly higher than commercial plant-based cheese, The fat content was 114.7 g kg-1 , lower than that of commercial dairy-based cheese. The rheology properties show that the viscoelasticity of the plant-based cheese is higher than that of dairy-based cheese and commercial plant-based. The microstructure results show that the type and content of protein has a significant impact on its microstructure. The Fourier-transform infrared (FTIR) spectrum of the microstructure shows a characteristic value at 1700 cm-1 , because the starch was heated and leached to form a complex with lauric acid under the action of hydrogen bond. It can be inferred that in the interaction between plant-based cheese raw materials, fatty acids serve as a bridge between starch and protein.

Nutritional quality and price of plant-based dairy and meat analogs in the Canadian food supply system

There has been an increased consumer interest and public health emphasis on plant-based protein foods, resulting in a rise in the availability of highly processed plant-based analogs. The objectives of this study were to assess the nutritional quality and the price of plant-based dairy and meat analogs compared to their respective animal-derived products and to examine the association between processing levels and the nutritional quality among these products. Using a branded food composition database, products in cheese, yogurt, milk, and meat categories were examined (n = 3231). Products were categorized as plant-based analogs versus animal-derived products using the ingredient list. Products were examined for their nutrient content, overall nutritional quality using the Food Standards Australia New Zealand nutrient profiling model, price, and processing levels using the NOVA classification. All plant-based analogs had lower protein and higher total carbohydrate, sugar, and fiber content compared to their respective animal-derived products. Compared to their respective animal-derived products, plant-based milk and meat analogs had lower energy, total fat, and saturated fat content; plant-based yogurt and meat analogs had lower sodium content; and all plant-based dairy analogs had lower calcium content. Plant-based cheese and yogurt analogs were more expensive than animal-based products; however, there was no significant difference among milk and meat products. There was no association between processing levels and overall nutritional quality among dairy and meat products. Plant-based analogs may be part of a healthy and affordable diet to reduce the intakes of nutrients of concern; however, additional compositional guidelines and/or labeling may be needed to highlight the differences in the levels of nutrients to encourage.

Are plant-based alternatives healthier? A two-dimensional evaluation from nutritional and processing standpoints

BACKGROUND

Plant-Based Alternative Products (PBAPs) to meat and dairy are increasingly available. Their relative nutritional quality in comparison to animal-based homologs is poorly documented.

OBJECTIVE

To characterize and evaluate the plant-based alternatives available on the market in Spain in comparison to animal products in terms of their nutritional composition and profile, and degree of processing.

METHODS

Nutritional information for PBAPs and homologs were obtained from the Spanish 'Veggie base', branded food composition database. Five PBAPs categories (cheese, dairy products, eggs, meat, and fish, n = 922) were compared to animal-based processed (n = 922) and unprocessed (n = 381) homologs, using the modified version of the Food Standard Agency Nutrient Profiling System (FSAm-NPS score) and NOVA classification criteria.

RESULTS

Compared to processed or unprocessed animal food, PBAPs contain significantly higher sugar, salt, and fiber. PBAPs for fish, seafood, and meat were lower in protein and saturated fatty acids. Overall, 68% of PBAPs, 43% of processed and 75% of unprocessed animal-homologs had Nutri-Score ratings of A or B (most healthy). About 17% of PBAPs, 35% of processed and 13% of unprocessed animal-based food were in Nutri-Score categories D or E (least healthy). Dairy, fish, and meat alternatives had lower FSAm-NPS scores (most healthy), while cheese alternatives scored higher (least healthy) than animal-based homologs. Unprocessed fish and meat were healthier than similar PBAPs based on FSAm-NPS criteria. Approximately 37% of PBAPs and 72% of processed animal-based products were ultra-processed food (NOVA group 4). Within the ultra-processed food group, Nutri-Score varied widely.

CONCLUSIONS

Most PBAPs had better nutrient profile than animal-based homologs. However, cheese, fish and meats PBAPs had poorer nutrient profile and were more processed. Given the high degree of processing and variable nutritional profile, PBAPs require a multi-dimensional evaluation of their health impact.

Nutritional Quality of Plant-Based Meat and Dairy Imitation Products and Comparison with Animal-Based Counterparts

While consumers are increasingly adopting plant-based meat and dairy imitation products, the nutritional quality and adequacy of those foods to act as a substitute is still under discussion. The Greek Branded Food Composition Database (HelTH) was expanded to map currently available meat and dairy imitations in Greece. Their main ingredient used, nutritional composition, and promotion as a healthy, nutritious food were described, and their overall nutritional quality using the Nutri-Score algorithm was evaluated. A total of n = 421 plant-based imitations were analyzed, made primarily of wheat or wheat mixes (83.5%) for meat imitations and grain (19.8%) or vegetable oil (17.1%) for dairy imitations. All meat imitations were high in protein and fiber, while, for dairy, only yogurts carried a protein content claim (80.9%). Imitation sausages, milk, and yogurt products had lower total fat and saturated fat content compared to their animal-based counterparts. All dairy imitations had lower protein content than animal-based dairy. The nutritional quality of imitation cheeses was graded as D-E, under the Nutri-Score system, compared to A-C for the animal-based cheese. Plant-based imitations have variable composition based on their main ingredient, and the substitution of specific food groups with plant-based alternatives may not support an equivalent or improved diet.

Sustainability and Gender Perspective in Food Innovation: Foods and Food Processing Coproducts as Source of Macro- and Micro-Nutrients for Woman-Fortified Foods

Micro- and macro-nutrient deficiencies among women are considered a global issue that the food industry has not adequately considered until recently. The industry must provide and guarantee a diversity of food products worldwide that allow women to get a correct and balanced diet according their life stage. The food industry must focus on this challenge within a framework of sustainable production, minimizing the use of natural resources and avoiding the emission of waste and pollutants throughout the life cycle of food. Food coproducts are presented as potential bioactive functional compounds which can be useful for technological purposes, due to the fact that they can serve as non-chemical, natural and health-improving food ingredients. In this review, we focus on the potential use of food processing coproducts which must be part of a strategy to promote and improve women's health and well-being. This knowledge will make it possible to select potential ingredients from coproducts to be used in the fortification of foods intended for consumption by females and to introduce sustainability and gender perspectives into food innovation. The attainment of fortifications for foods for women has to be linked to the use of sustainable sources from food coproducts in order to be economically viable and competitive.

Vegan milk and egg alternatives commercialized in Brazil: A study of the nutritional composition and main ingredients

Worldwide, there is an increasing demand for plant-based food due to sustainable, health, ethical, religious, philosophical, and economic reasons. In Brazil, 14% of the population declares themselves vegetarians, and a noticeable increase in the consumption of vegan products is also noted. Substitution of animal dairy and egg is challenging from both sensory and nutritional aspects. Yet, there are no data regarding the nutritional value and ingredients of Brazilian commercial dairy and egg substitutes. Therefore, this study aimed to analyze the nutritional composition and used ingredients in Brazilian commercial vegan alternatives to dairy and eggs to provide information for Brazilian consumers of these products. A cross-sectional quantitative study was carried out in three steps: (i) sample mapping. (ii) data collection, and (iii) statistical analysis. A total of 152 samples were included. No differences were found between the energy value and total fat of vegan products and their animal counterparts. Vegan products showed higher amounts of carbohydrates and dietary fiber, and only the vegan versions of beverages and cheeses showed less protein than their counterparts. Cashews, rice, coconut, and soy were the most used ingredients in dairy substitutes. Emulsions of oil, starch, and isolated protein were used in vegan egg products. Most vegan beverages presented sugar in their composition. Vegan alternatives of dairy and eggs might be suitable for substituting their animal counterparts, but given that traditional versions of cheeses and milk are sources of protein in omnivorous diets, for equivalent nutritional replacement in vegan products, it is necessary to improve the protein content of their vegan counterparts.

Observational and clinical evidence that plant-based nutrition reduces dietary acid load

Contemporary diets in Western countries are largely acid-inducing and deficient in potassium alkali salts, resulting in low-grade metabolic acidosis. The chronic consumption of acidogenic diets abundant in animal-based foods (meats, dairy, cheese and eggs) poses a substantial challenge to the human body's buffering capacities and chronic retention of acid wherein the progressive loss of bicarbonate stores can cause cellular and tissue damage. An elevated dietary acid load (DAL) has been associated with systemic inflammation and other adverse metabolic conditions. In this narrative review, we examine DAL quantification methods and index observational and clinical evidence on the role of plant-based diets, chiefly vegetarian and vegan, in reducing DAL. Quantitation of protein and amino acid composition and of intake of alkalising organic potassium salts and magnesium show that plant-based diets are most effective at reducing DAL. Results from clinical studies and recommendations in the form of expert committee opinions suggest that for a number of common illnesses, wherein metabolic acidosis is a contributing factor, the regular inclusion of plant-based foods offers measurable benefits for disease prevention and management. Based on available evidence, dietary shifts toward plant-based nutrition effectively reduces dietary-induced, low-grade metabolic acidosis.

Quality and health dimensions of pulse-based dairy alternatives with chickpeas, lupins and mung beans

Health and environmental issues regarding dairy consumption have been highlighted in recent years leading to tremendous consumer demand for plant-based substitutes. In this review, we focused on quality and health dimensions of pulse-based dairy alternatives (PuBDA) using chickpeas, lupins and mung beans. Appraisal of existing documents show that there is limited information on PuBDA with the said pulses compared to similar materials such as soy and pea. Most of the studies focused on milk or fermented milks, either in full or partial substitution of the dairy ingredients with the pulses. Issues on stability, sensory properties, shelf life and nutritional quality were underlined by existing literature. Although it was emphasized in some reports the health potential through the bioactive components, there is scarce data on clinical studies showing actual health benefits of the featured PuBDA in this paper. There is also a scant number of these PuBDA that are currently available in the market and in general, these products have inferior nutritional quality compared to the animal-based counterparts. Technological innovations involving physical, biological and chemical techniques can potentially address the quality problems in the use of chickpeas, lupins, and mung beans as raw materials in dairy alternatives.

Nutritional Content of Non-Dairy Frozen Desserts

There is a growing interest in non-dairy alternatives fueled by concerns about personal health and the health of the planet. Sales of non-dairy frozen desserts have increased along with other non-dairy alternatives such as plant-based beverages, cheeses, yogurts and creamers. The aim of this study was to conduct a cross-sectional survey of plant-based frozen desserts to determine their nutritional content. A total of 358 plant-based frozen desserts were analyzed from the nutrition label listed on the commercial container. The various products were based upon coconut (n = 126), oat milk (n = 63), almonds (n = 42), cashews (n = 25), soy (n = 11), macadamia milk (n = 9), olive oil (n = 8), faba bean (n = 8), canola oil (n = 8), rice milk (n = 6), sunflower milk (n = 6), avocado (n = 5), pea protein (n = 5) and various fruits, nuts and mixed blends (n = 36). While 90% of the frozen desserts had high sugar levels, 73% had high levels of saturated fat (due to the presence of coconut oil) and only one in four had high levels of fat. None of the products were fortified with calcium, vitamin D or B12, but one in six products had iron levels/serving of at least 10% of Daily Value (DV) and 1 in 6 had protein levels/serving similar to regular dairy ice cream. Food manufacturers need to produce new non-dairy frozen desserts that are more nutritious, since few brands (such as those based upon avocado, apple and hemp protein, or fava bean) presently provide consumers choices with lower saturated fat and sugar levels and/or higher protein levels.

Vegan nutrition: a preliminary guide for health professionals

Since the beginning of the 21st century, interest in vegan diets has been rapidly increasing in most countries. Misconceptions about vegan diets are widespread among the general population and health professionals. Vegan diets can be health-promoting and may offer certain important advantages compared to typical Western (and other mainstream) eating patterns. However, adequate dietary sources/supplements of nutrients of focus specific to vegan diets should be identified and communicated. Without supplements/fortified foods, severe vitamin B12 deficiency may occur. Other potential nutrients of focus are calcium, vitamin D, iodine, omega-3 fatty acids, iron, zinc, selenium, vitamin A, and protein. Ensuring adequate nutrient status is particularly important during pregnancy, lactation, infancy, and childhood. Health professionals are often expected to be able to provide advice on the topic of vegan nutrition, but a precise and practical vegan nutrition guide for health professionals is lacking. Consequently, it is important and urgent to provide such a set of dietary recommendations. It is the aim of this article to provide vegan nutrition guidelines, based on current evidence, which can easily be communicated to vegan patients/clients, with the goal of ensuring adequate nutrient status in vegans.
