Conventional meat consumption has triggered an environmental burden along with effects on different disease spectrums according to existing research. The dietary patterns adopted by consumers significantly impact both planetary and individual health. Interventions are needed to support the protein transition. However, there is not yet an overview of interventions towards acceptance of novel proteins available. This systemic review highlights different varieties of alternative proteins and interventions adopted to increase the acceptance of alternative protein sources. Educational intervention, persuasion, training, and modeling approaches are summarized in this review. Furthermore, behavioral models triggering the consumer’s response towards different alternative proteins are also discussed. The systemic review highlights that consumer acceptance varies among different alternative proteins. Food choice motives, familiarity, food neophobia, disgust, and cultural norms are among the various drivers of consumer acceptance. A comparison of these drivers indicates inconsistencies, presenting the need for future research.

Within the framework of this study, the effect of nanoparticles of the essential trace element selenium stabilized by Polyvinylpirrolidone (PVP) C15 (8 ± 2 kDa) and ascorbic acid on the germination of barley seeds has been studied. Selenium nanoparticles stabilized by PVP C15 (8 ± 2 kDa) and ascorbic acid, characterized by a spherical shape, monodisperse size distribution, and a diameter of about 70 ± 5 nm, were obtained by the chemical reduction method. The experiment compared the effect of selenium nanoparticles and selenous acid on seed germination. The positive effect of preparation of selenium nanoparticles stabilized by PVP C15 (8 ± 2 kDa) and ascorbic acid on the length of roots and shoots, the number of roots, and the percentage of seed germination has been revealed. It was determined that the highest percentage of Hordeum vulgare L. culture seed germination was achieved using a preparation of selenium nanoparticles stabilized by PVP C15 (8 ± 2 kDa) and ascorbic acid at a concentration of of 4.65 µg/mL. Analysis of the results showed that selenium in the form of nanoparticles has an order of magnitude that is less toxic than in the form of selenous acid. The study of morphological and functional parameters during the germination of Hordeum vulgare L. seeds allowed us to conclude that selenium nanoparticles can be successfully used in agronomy and agriculture to provide plants with the essential microelement selenium, which is necessary for the normal growth and development of crops.

In this work, we obtained silver nanoparticles stabilized with polyvinylpyrrolidone, ranging in size from 70 to 110 nm, which exhibits good crystallinity and anisotropic structure. For the first time, we studied the influence of the molar ratio of silver between silver and peroxide on the oxidation process of the nanoparticles and determined the regularities of this process by analyzing changes in absorption spectra. Our results showed that at molar ratios of Ag:H₂O₂ = 1:1 and 1:5, dependences of changes in the intensity, position and half-width of the absorption band of the plasmon resonance are rectilinear. In vivo studies of silver nanoparticles have shown that silver nanoparticles belong to the toxicity class III (moderately hazardous substance) and to the third group according to the degree of accumulation. We established that silver nanoparticles and oxidized silver nanoparticles form a uniform layer on the surface of the suture material. We found that the use of the suture material with silver nanoparticles and oxidized silver nanoparticles does not cause allergic reactions in the organisms of laboratory animals.

Environmentally intense and negative consequences relateing to conventional meat production systems have induced some actors to suggest alternative meat sources. Diseases carried by animals, human perception of cruelty to animals, and public health concerns about cardiovascular diseases have provided the basis for the development of cultured meat. The current market is influenced by many factors, including regulators, affordability, religion, and media perception. The existing cultured meat market is also regulated by legislatures, affordability, consumer religion, and the media. Consumer perception is distributed across various aspects, including ethical priorities, nutritional profile of the meat consumed, age-based acceptance, gender differentiation, political orientation, land-based attitude, education status, socioeconomic factors, and familiarity factor with the existing product in the market. Inhibiting barriers reported among consumers—including low naturalness, safety, nutritional concerns, trust, neophobia, economic, and ethical approaches—should be employed as marketing tactics directly to address their respective concerns. Tissue culture, starter cells, printing, and 3D printing are some of the methods currently being used for the production of cultured meat. Similarly, many hybrid technologies are also being used to produce meat-like products to increase consumer familiarity along and market presence. Existing research frameworks have improved the previous mindset of consumers with media coverage, educational frameworks, and the textural attributes of cultured meat. Additional benefits of CUME may include being environmentally friendly with less production of greenhouse gases. However, consumer trust, affordability, improving nutritional status, and widescale adoption are just a few of the parameters that need to be addressed to enhance consumer acceptability of these products. The aim of this article was to analyze the current state of cultured meat and the marketing content challenges and strategies used to advance public acceptance of cultured meat.

Due to rapid globalization in the world, the understanding of cultural differences, such as beliefs, values, ways of thinking, and perceptions about new technologies in food processing have also increased. Since the 1990s, when genetically modified (GM) foods were introduced into the food supply, they have provoked many debates. In this review, it was identified and discussed how social and psychological factors influence public attitudes to GM foods and the perceptions of consumers in using GM foods. According to this review, GM foods are deemed unnatural and artificial, thus affecting the overall acceptance of their application. Due to the concerns about their effects on the environment and human health, people expect an assessment of the known or possible dangers, as well as the preventative management of the risks. Providing adequate information about GM foods via a compulsory labeling policy may serve as an appropriate way to increase public awareness and acceptance of GM foods.
