Flavor-switchable scaffold for cultured meat with enhanced aromatic properties

Cultured meat is emerging as a new type of food that can provide animal protein in a sustainable way. Many previous studies employed various types of scaffolds to develop cultured meat with similar properties to slaughtered meat. However, important properties such as flavor were not discussed, even though they determine the quality of food. Flavor characteristics vary dramatically depending on the amount and types of amino acids and sugars that produce volatile compounds through the Maillard reaction upon cooking. In this study, a flavor-switchable scaffold is developed to release meaty flavor compounds only upon cooking temperature mimicking the Maillard reaction of slaughtered meat. By introducing a switchable flavor compound (SFC) into a gelatin-based hydrogel, we fabricate a functional scaffold that can enhance the aromatic properties of cultured meat. The temperature-responsive SFC stably remains in the scaffold during the cell culture period and can be released at the cooking temperature. Surprisingly, cultured meat fabricated with this flavor-switchable scaffold exhibits a flavor pattern similar to that of beef. This research suggests a strategy to develop cultured meat with enhanced sensorial characteristics by developing a functional scaffold which can mimic the natural cooking flavors of conventional meat.

Perceived determinants of food purchasing behavior applicable for behavioral change toward sustainable consumption

The paper deals with consumer behavior in the context of sustainable development of society. A questionnaire survey of 732 respondents was used to understand the determinants of food purchasing behavior toward sustainable consumption. The paper identifies the factors that the consumer determines in food purchasing as critical in terms of sustainable consumption and requiring behavioral change toward sustainability in terms of healthy lifestyle, reduction of food wastage, and conscious consumption. Respondents commented on 22 factors and the quantification of their impact on food waste and expressed the strength of opinion on sustainability issues. To evaluate the collected data, PCA factor analysis was used, which defines the importance of each factor by identifying artificial hypothetical variables, which are “Sustainability” and targeted education as appropriate tools for it, “Food usability,” which is a recommendation to producers by food quality, offering new types of food with longer shelf life, as well as “Pricing,” “Quality” and “Convenience.” The authors also sought to understand what measures they take in relation to waste and how they behave toward sustainable consumption and environmental protection. They created 14 content questions on this topic and by using factor analysis, 3 hypothetical variables were created, namely “Sustainable behavior” which expresses a healthy lifestyle, “Thoughtful purchase” which expresses a relationship with environmental protection before purchasing and “Zero waste” which means that the household tries to make additional use of food. Thus, it seeks a use for the food it cannot consume at a given time and creates a supply for other consumers. This behavior is a good prerequisite for achieving a change in consumption behavior. The influence of selected sociodemographic indicators on the frequency of wastage was also investigated using the χ-squared test. The influence of generation and number of children in the household on the frequency of wastage was demonstrated. The results of the analyses on the importance of individual factors and consumer behavior, especially of the young generation, argue for education on sustainable consumption.

Improving the composition of mare’s milk as a raw material for specialized products

This article presents research data conducted to improve the composition of mare’s milk as a safe raw material for food production. The problem of producing specialized products is very acute and requires a solution. The Republic of Bashkortostan, as a region of developed dairy horse breeding, is a leading region in the production of mare’s milk. This raw material is promising for the production of new types of food. To develop technology for new types of milk-based nutrition, it is necessary to improve the composition of this raw material by introducing additives containing microelements into the diet of mares. We propose the use of Sel-Plex additive, containing selenium in organic form. The following were determined: the selenium content in mare’s milk, the physicochemical composition of milk, the vitamin composition of milk, as well as the content of heavy metals. The findings indicate an improvement in the quality of mare’s milk and the possibility of creating new types of specialized products based on it, including for nutrition of athletes. To increase the nutritional properties of mare’s milk, it is recommended to use the selenium-containing additive Sel-Plex in its production at a rate of 1 g. per 100 kg of live weight.

Legal Aspects of Microalgae in the European Food Sector.

The interest in microalgae as food in Europe is growing due to its remarkable features that can foster a sustainable economy. The lack of tradition on their use among Europeans is changing and a demand for more sustainable products is increasing. The legal framework from the microalgae stakeholders' point of view has been consistently identified as a bottleneck, regardless of its nutritional value and potential to provide added-value metabolites. Microalgae-based products have been mostly consumed as food supplements, which are characterized by some general uncertainty with regards to food security of products sourced from non-European countries. The novel foods regulation is a landmark in Europe's food law defining the conditions in which a new type of food can be commercialized. Currently, a more simplified and centralized version is in place, and around eleven microalgae-based products are on the market; however, more than half are represented by Schizochytrium sp. derived products (DHA-rich oil). Microalgae have immense potential as a sustainable food source; nonetheless, there is limited experience in assessing the safety of these microorganisms, considering the uncertainty around undesirable substances present in the way they are produced and their diverse metabolites. Here, we overview the regulatory use of microalgae as food in Europe with a focus on market introduction, highlighting the administrative procedures and scientific requirements to assess food safety. We also discuss the implications of the Transparency regulation related to microalgae as novel foods and provide considerations for a more solid interaction between academia and industry.

THE RELATIONSHIP BETWEEN MOTHER'S PARENTING PATTERNS AND DIFFICULT EATING BEHAVIOR IN PRE-SCHOOL AGE CHILDREN

Background: Factor one mother complained that her child was very difficult to eat and only wanted to eat food when gathering with friends or invited to refresh. Objective: The purpose of the study was to determine the relationship between maternal parenting and difficult eating behavior in preschool age children in Pertiwi Kindergarten, Mancar Village, Peterongan District, Jombang Regency. Methods: The research design used correlational analysis with a cross sectional approach.

Collecting data using a questionnaire. The statistical test used in this study was Spearmen Rank Test. Result: The results showed that the permissive mother's parenting style with difficult eating behavior in children was mostly sufficient as many as 19 people (52.8). While the behavior of difficult eating in children with an authoritarian parenting pattern is as small as 3 people (8.3%). Spearmen Rank test showed value 0.000 (r value < 0.05). Then H1 is accepted, which means that there is a relationship between maternal parenting patterns and difficult eating behavior in preschool-aged children in Pertiwi Kindergarten, Mancar Village, Jombang Regency. Conclusion: Good parenting patterns for children who have difficulty eating so that nutritional factors do not occur are expected to provide interesting food so that children do not get bored with the food provided, limit the consumption of snacks and snacks that make children full before eating the main meal, and provide types of food that are suitable for children. nutrition for children. Trying to get children to eat by feeding and teaching children to eat new types of food.

A study on the adoption intention of cold chain prepared Dishes based on consumer orientation mentality

Background: Cold chain prepared dishes, as a new type of food with low temperature and dual attributes, have attracted more and more attention from consumers. From the perspective of consumers' brand positioning mentality, this study integrated the brand, quality and other attributes of cold chain prepared vegetables, and studied the positioning mentality and adoption behavior of Chinese consumers In this study, three cold-chain prefabricated dishes, "pickled cabbage fish", "tomato Braised beef brisket" and "Huangpi fishball", were selected as investigation objects. Contribution: The contribution of this study is that different food value attributes explain the law of consumers' willingness to adopt cold chain prepared dishes through brand positioning mentality, and find out how different degrees of vulnerability and quality warranty Method: Based on ZMET survey method, product effect data were used to analyze and verify structural equation model. Results: Different value evaluation directly affects consumers' brand positioning mentality, brand positioning mind as an intermediate variable has a significant correlation with adoption intention. The degree of vulnerability moderates the relationship between value evaluation and brand positioning mentality, and the degree of warranty period regulates the relationship between quality value, brand positioning mentality and adoption intention respectively. Conclusion: It also provides new marketing tools and theories for entrepreneurs and marketers in the cold chain food industry, which contributes to the promotion and diffusion of cold chain prepared food for consumers

Comparative characteristics of the amino acid composition of protein from traditional sources and entomoprotein: calculated data

The growth of the world population leads to an increase in demand for food consumption. Along with the projected reduction in demand for meat products, a search is underway for a new type of food ("novel food"), one of the promising options for which are insects. In 2023 the European Commission has registered flour made from house cricket (Acheta domesticus) as a "novel food" for human consumption. Currently, the amino acid composition of both new types of food and the diet that includes them is not regulated. Accordingly, the potential amino acid imbalance in the diet when entomoprotein is included need to be further investigated. The aim of the study was to characterize the amino acid composition of a simulated diet using protein obtained from house cricket. Material and methods. To assess the balance of diets in terms of amino acid composition, a comparative analysis was made of the actual diet containing protein from traditional foods (scenario 1) and the diet with the likely replacement of beef, pork and poultry with a product containing A. domesticus protein (entomoprotein) (scenario 2). The volume of food consumption has been calculated based on the results of the assessment of a sample survey of household budgets. The study included foods with an established value of annual consumption, that was calculated as daily consumption. The content of essential amino acids in food sources of protein, as well as in the domestic cricket protein, was evaluated using the data from relevant sources. Dietary balance was assessed by calculating its digestibility using data on amino acid scoring, the utility of essential amino acids, the excess content of individual essential amino acids, and the comparable excess content of essential amino acids. Results. We determined the daily consumption volumes of basic foods, formed consumption scenarios, including with the potential use of a protein product based on entomoprotein. Comparative analysis of the amino acid composition of the diet showed significantly higher content (from 1.4 up to 2.9 times) of amino acids in the diet in scenario 2. The results of calculating the amino acid score and utility coefficient showed that a diet using entomoprotein could provide a better usage of amino acids for protein synthesis compared to the «traditional» diet, however, the digestibility of protein from the traditional diet is higher compared to entomoprotein (96.8 vs 89.1%). Conclusion. Despite the fact that the utility of essential amino acids in the scenario of replacing meat products with a product containing A. domesticus entomoprotein is higher, while the digestibility of protein is lower, the differences identified are insignificant.

The remarkable observation for a mallard (Anas platyrhynchos) food from estuarine/coastal area (İzmir/Turkey): A mosquitofish (Gambusia holbrooki)

The purpose of this study is to create awareness about the species of mosquito fishes (Gambusia holbrooki Girard, 1859) both vectors and ways of introduction to new aquatic habitats. Because the species creates risks, especially for the circumstance of the native and endemic fish fauna, studies about introduction stories of the species are quite important to prevent the risk. In the current report, mosquitofishes which are known as a highly invasive species were found in the crop content of a hen mallard duck (Anas platyrhynchos L., 1758) in an estuarine area, the Gediz River Basin (İzmir, Turkey). This report is the first record of a duck consuming mosquitofish. Although nevertheless, it is known that mallard duck feeding behaviour does not predominantly contain fish (they mainly feed on plant seeds), according to this observation, mosquitofish might be added to the prey list of mallards as a new type of food. Therewith, this feeding behavior also indicates that ducks might be a potential vector for the transport of invasive mosquitofishes.

Novel Technologies for Seaweed Polysaccharides Extraction and Their Use in Food with Therapeutically Applications-A Review.

The use of seaweed for therapeutic purposes is ancient, but only in the last decade, with advanced technologies, has it been possible to extract seaweed’s bioactive compounds and test their potential properties. Algal metabolites possess nutritional properties, but they also exhibit antioxidant, antimicrobial, and antiviral activities, which allow them to be involved in several pharmaceutical applications. Seaweeds have been incorporated since ancient times into diets as a whole food. With the isolation of particular seaweed compounds, it would be possible to develop new types of food with therapeutically properties. Polysaccharides make up the majority of seaweed biomass, which has triggered an increase in interest in using seaweed for commercial purposes, particularly in the production of agar, carrageenan, and alginate. The bio-properties of polysaccharides are strictly dependent to their chemical characteristics and structure, which varies depending on the species, their life cycles, and other biotic and abiotic factors. Through this review, techniques for seaweed polysaccharides extraction are reported, with studies addressing the advantages for human health from the incorporation of algal compounds as dietary supplements and food additives.

Peptidomics comparison of plant-based meat alternatives and processed meat after in vitro digestion

Plant-based meat alternatives (PMAs) is a new type of food that meets people's health needs, but the lack of awareness of its nutritional properties limits product development and promotion. Here, we compared the similarities and differences of the nutritional properties of PMAs and meat before and after in vitro simulation of gastrointestinal digestion by chemical composition analysis, peptidomics and bioactivity tests. The molecular weights of Plant-based meat alternatives derived peptides (PDPs) as well as meat-derived peptides (MDPs) in the beef and pork groups were mainly concentrated in the low mass range from 800 Da to 1500 Da. The principal component analysis indicated that the composition of MDPs in the beef and pork groups significantly differed from PDPs but overlapped slightly with the chicken group. Also, there were very few common peptides among them. The proportion of high-biological-scoring peptides (33.3%–40%) in PDPs was more than that in MDPs (4.8%–20.8%). PDPs were predicted to have higher antibacterial activity than others. PDPs and MDPs showed a certain antioxidant capacity and angiotensin converting enzyme inhibitory activity (62.2%–92.5%) in vitro. Some peptides weakly inhibited the growth of Escherichia coli (ATCC 25922) and Staphylococcus aureus (ATCC 25923) while promoting the growth of probiotics. This research provides a theoretical basis for in-depth exploration of the nutritional characteristics of PMAs.

How Does Adolescents' Usage of Social Media Affect Their Dietary Satisfaction?

In order to improve the health status of adolescents, studies are needed to illuminate the essence of their general and dietary lifestyle. Thus, we conducted this study to verify meaningful relationships between adolescent usage of social media (USM), which plays an important role in their life, their food consumption behavior (FCB), and their dietary satisfaction. This study used two analysis methods: t-tests and structural equation modeling (SEM). This study verified whether there was a significant difference in adolescent FCB depending on their USM using t-tests. This study proposes that the following FCBs showed significant differences between users and non-users of social media in adolescents: a tendency to try new types of food (t = 2.134, p < 0.05), a tendency to avoid foods with harmful risks such as suspected spoilage (t = 3.513, p < 0.001), a tendency to eat bread or fruit for a simple breakfast (t = −3.893, p < 0.001), and a tendency to often use home meal replacements (HMR), eat out or have food delivered (t = −3.245, p < 0.01). Furthermore, this study used SEM to verify the causal relationship between adolescent USM and their dietary satisfaction. According to the results of SEM, adolescents’ USM mediated by the FCB of preferring convenience fully mediates the negative relationship between adolescent USM and their dietary satisfaction (p < 0.01). It is necessary to reverse the situation in which adolescent dietary satisfaction decreases as their FCB of preferring convenience increases. Government regulations for food companies and autonomous efforts for quality improvements on their part are needed.

Research of technological properties of bread made with the addition of beet kvass

The issue of healthy eating has always been relevant, especially this problem has been exacerbated by the rapid development of food technology and the production of a significant number of semi-finished products. As a result, there is a need to develop new types of food, including unleavened and low-calorie bread, bakery products enriched with vitamins, minerals, plant supplements. The aim of the work was to substantiate the technology of bread production with the use of beet kvass and to investigate the physico-chemical quality indicators of experimental samples of finished products. Technological indicators that characterize the quality of bread: moisture, porosity, crumbliness, acidity were determined by generally accepted methods. Bread made with beet kvass has been found to have well-developed crumb porosity, does not crumble for a long time, hardens slowly, and is resistant to microbiological spoilage. The crumb is not deformed and elastic when pressed. Replacing part of the water during the kneading of wheat dough with beet kvass (50 % by weight of flour) makes it possible to intensify the maturation of semi-finished products, both in traditional and accelerated technologies, to create a more complete nutrient medium for yeast activation, to obtain high quality bakery products storage. It has also been found that during the storage of bread, the hydrophilic properties of the crumb, its crumbliness changes slightly. The drying process is most intense during the first day, then slows down.

RELATIONSHIP BETWEEN PICKY EATING AND NUTRITIONAL STATUS IN PRESCHOOL CHILDREN

AbstractBackground : Picky eating is a condition when children refuse to eat certain foods. Picky eating usually stops within 2 years as part of the growth process, those who stop picky eating after more than 2 years tend to be more difficult to accept new types of food. This may be unfavorable for a child's growth and nutritional status. The study was conducted to analyze the relationship between picky eating with nutritional status in preschool children. Method : This research method was observational analytic quantitative with cross sectional research design. Sampling used a total sampling technique. Data was collected in 3 preschool in October 2019 using primary and secondary data. Primary data was collected using a questionnaire given to parents to measure picky eating used Child Eating Behavior Questionnaire (CEBQ). Nutritional status was measured bytaking anthropometric measurements of children. Data analysis used fisher exact correlation tests. Results : The results obtained a sample of 78 respondents from 3 preschool. The average age of children was 48,37 months with a median was 49,00. The result showed 62,8% of children were female, 55,1% were second or more children, 88,5% had routine growth monitoring, 53,8% were in extended families, and 73,1% of children were taken care by their parents. The prevalence of children with picky eating was 70,5%. Nutritional status measurements found 1.3% of children included in underweight category and 83,3% normal. Results of the analysis of the relationship between picky eating and nutritional status showed p value = 0,819. Conclusion : There was no relationship between picky eating with nutritional status in preschool children.

The house cricket – a new source of food or a new source of allergens?

Nowadays, there is a growing demand for new types of food which are less resource consuming and cheaper to produce. One solution could be to introduce edible insects on the food market in developing countries, but also in Europe and North America, where entomophagy is a less common practice. The house cricket (Acheta domesticus) is of particular interest because it is an important source of protein, although it is often found as a hidden source in food. Thus, several issues related to consumer’s safety arise. Firstly, there are risks related to contamination with microorganisms and toxins. On the other hand, there is the problem of primary allergen sensitization and the increased potential for cross-reactivity to cricket proteins, with the possibility of developing allergic reactions, up to anaphylactic shock. The cricket, as a member of the arthropod phylum, has many proteins that are similar to those of other insects, house dust mites, crustaceans and also mollusks. The most common panallergens that are responsible for cross-reactions are tropomyosin and arginine kinase. A question which is raised is whether cricket is a new source of food or a new source of allergens.

The comprehensive studies of Hermetia illucens larvae protein's biological value

A high protein content in the insect biomass allows to classify this product as a very promising source of protein, comparable in nutritional and biological value with proteins of animal origin. Despite a long history of safe use, in some countries insects are considered a new type of food which safety must be proven before entering the food market. The long-term Russian experience in novel food's research allows to identify the crucial stages, among which, along with toxicological and allergological tests, the protein's biological value determination takes an important place. The conclusion about the biological value of protein is formed on the basis of integrated use of chemical and biological methods, which gist comes down to the study of the nitrogen balance in the growing organism (biological method) and the calculation of the amino acid score (chemical method). The aim of the research was the comprehensive assessment of Black soldier fly (Hermetia illucens) larvae protein's biological value using chemical and biological methods. Material and methods. Biological studies based on measuring of net protein ratio/net protein utilization were performed on 28 growing (between 25-50 days of life) male Wistar rats, with an initial body weight of ~65.5±1.2 g. Rats in the control group (n=14) received a semi-synthetic casein diet with a protein content of ~12% in calories, the test group (n=14) received a diet including an equivalent amount of H. illucens protein. The diet's ingredients were replaced with the consideration of the proteins, fats, and carbohydrates content in the included product following the principle of isocaloricity and isonitrogenicity (by mass fraction of total nitrogen). H. illucens biomass and casein in the test and control groups, respectively, were the main significant sources of nitrogen in the diet. Body weight, feed intake, and fecal and urine nitrogen losses were measured during the experiment. The biological value and digestibility of protein were judged by coefficients of protein efficiency ratio, net protein ratio, true protein digestibility, true protein biological value, true net protein utilization. Chemical studies included studies of the amino acid composition of H. illucens biomass protein and calculation of the digestible indispensable amino acid score (DIAAS). Results. The general condition of animals of the both groups during the whole experiment was satisfactory, the weekly body weight increase corresponded to the level of growth typical for Wistar rats, intergroup differences were not detected. Despite the fact that in a number of indicators the test group animals differed from the control [there were noted a decrease of the net protein ratio (by 5%, p>0.05), true protein digestibility (by 11%, p<0.05), net protein utilization (by 13%, p<0.05), caused by increased excretion of nitrogen with urine (by 8%, p>0.05) and feces (by 186%, p<0.05), with the same amount of nitrogen intake], the test rats' growth rate and the nitrogen's retention degree indicate a relatively high biological value of insect protein. According to the DIAAS, H. illucens protein is characterized by high content of histidine, threonine, valine, isoleucine and leucine (DIAAS=100 and more), and is also a source of sulfur-containing amino acids - methionine and cysteine (DIAAS=86) and lysine (DIAAS=97). Conclusion. The comprehensive studies of Hermetia illucens larvae protein's biological value demonstrated a high protein content, its balanced amino acid composition and high biological value, which allows to consider Hermetia illucens as a potential source of complete dietary protein.

THE EFFECT OF PLANT PROTEINS ON THE FORMATION OF STRUCTURAL AND RHEOLOGICAL PROPERTIES OF NOUGAT

This paper considers the problem of increasing the nutritional value of whipped confectionery such as nougat by using hemp- based and soya-based protein-containing ingredients. The main tendencies of obtaining new types of food based on plant proteins with complete amino acid composition are described. The paper presents information on cultivating and using hemp and soya both in Ukraine and in the world, and suggests how products of their processing can be applied to improve the quality and increase the biological value of confectionery. It has been investigated what effect protein-containing ingredients obtained from hemp and soya have on the structural properties of foam in the technology of whipped confectionery such as nougat. It has been established that increasing the amount of plant protein additives leads to a decrease in the foaming ability, but the stability of protein foams increases. Adding 10% of protein-containing hemp additives increases the foam stability by 6%, while protein-containing soya additives increase it by 5%. The paper presents the results of studying the structural and rheological properties of nougat mass with protein-containing plant additives in the amount 2.5–10% of the weight of sugar. It has been determined that adding protein-containing hemp and soya ingredients increases the viscosity and plastic strength of the products and stabilises their structure. The effect of different amounts of nuts on the kinetics of nougat crystallisation has been studied. It is recommended to add 5% of hemp and 7.5% of soya protein-containing additives instead of sugar during the whipping of nougat mass, because it reduces the whipping time and has a positive effect on structure formation. The recommended amount of roasted pistachio kernels in the samples suggested is 25–35% of the total weight of nougat, with the resting time 30–60 minutes and the moulding temperature 50–55°C. The nutritional value of the new products with protein-containing hemp and soya ingredients and nuts has been calculated. It has been noted that nougat has been enriched with protein, unsaturated fatty acids, and minerals (potassium, calcium, magnesium, phosphorus).

Implementation of Zhu Takaoka Algorithm in Android-Based Restaurant Mobile Applications

Competition of fast food restaurants at this time is getting tougher, this can be seen from the development of several fast food restaurants or fast food restaurants that exist, including Kentucky Fried Chicken, California Fried Chicken, Mc Donalds, New York Chicken, and Texas Chicken. This makes all restaurants competing in attracting consumers to buy products from the restaurant. Various efforts have been made ranging from opening branches, offering saving packages to consumers, and adding new types of food. Fast food can be interpreted as food that can be prepared to be served and consumed in a short time and can be eaten quickly. Ordering food and drinks is preferred at the current restaurant. The process of choosing food and beverage menus that are currently running at Garuda restaurants is still using menu books, menu books containing a large number of food and beverage menus, many menus are a problem for consumers because consumers find it difficult to find food and beverage menus quickly. And for the way to choose the menu itself, still see the list of food and beverage menu

Dynamics of innovations in food technologies: from specialization to personalization

Dynamically changing global trends in the field of innovative foods in recent years are aimed at the development of technologies that ensure the formation of segments of new types of products, positioned as healthy products. Scientific directions of research and development in this area, retrospectively related to the development of nutrition science, are focused on solving an interdisciplinary set of tasks to create new types of foods, the distinctive features of which are the specified compositions and properties that determine the health benefits (functional foods) and directed physiological effectiveness (specialized foods for preventive and therapeutic nutrition). Characteristics of the composition of a specific specialized food are formed in connection with its intended purpose on the basis of medico-biological requirements taking into account specific features of nutrition of the population in total, and its separate groups or individual. Depending on the mentioned specifics, the development of specialized foods provides for different levels of determining human needs: from energy consumption to the metabolome. Taking into account these features, the development tasks, methods of proving the effectiveness and conditions for using specialized foods in order to achieve maximum effect are determined. In studies of prophylactic or therapeutic foods, the subject of evaluating the effectiveness of a specialized product is the clinical effect, so innovative research in this category of products is associated with the creation of a universal approach to the development, use and evaluation of the effectiveness of biologically active substances and containing them specialized foods for the correction of metabolic disorders. The vector of innovative development of technologies for the production of specialized foods is focused today on the direction of personalized nutrition. The basis of scientific justification of the distinctive features of the compositions and properties, as well as technological know-how of the production of personalized foods, is the information about the metabolome directly related to the biological functions of the body.

A Comprehensive Review of the Benefits of and the Barriers to the Switch to a Plant-Based Diet

In recent decades, the food industry has been faced with new challenges, and it has had to develop new types of diets and produce new types of foods that can slow down the spread of chronic diseases. The aim of our research was to identify the characteristics of plant-based nutrition, based on international and Hungarian literature. The comprehensive analysis was performed based on the theoretical model called Theory of Planned Behavior, in the course of which the perceived and objective benefits of and barriers to the conversion to a plant-based diet were examined. According to our results, the main benefits of plant-based nutrition are its many factors associated with a reduction in risk of developing numerous chronic diseases. This is followed by benefits of well-being and satisfaction, followed by ethical and environmental benefits. The most commonly reported inhibitory factor of a vegetarian diet is the enjoyment of eating meat and the difficulty in giving up meat consumption. This is followed by health considerations, e.g., lack of various ingredients in foods. Convenience and taste factors are also important disincentives, as well as the irrelevant nature of some plant-based nutrition information sources. Besides, social barriers, negative discrimination, and negative effect on mental health associated with them can also be a hindrance, as can financial barriers. The classification developed during our analysis can serve as a relevant guideline for decision-makers, and also as a basis for further primary qualitative and quantitative research.
