Пищевые привычки и потребности в питательных веществах складываются на протяжении всей жизни человека под влиянием различных факторов, однако неоспоримым остается факт биологической потребности организма в незаменимых аминокислотах и как следствие - в доступных, полноценных белках. Поиск новых источников белка и развитие технологий его получения, воспроизводства, переработки, сбережения всегда в центре внимания пищевой промышленности. Потребность растущего населения Земли в доступных пищевых ресурсах, богатых полноценным белком, с каждым годом только возрастает. Выбор оптимальной формулы, способа переработки или сочетания композиции натуральных белков растительного происхождения, способных выступать в качестве возобновляемого источника незаменимых аминокислот, в целях полноценной замены белков животного происхождения, в частности молочных, в соответствии с принципами экономической целесообразности является основной движущей силой исследований и разработок. Актуальность обзора сырьевых источников и формирование критериев выбора растительного сырья с целью применения в моделях конструирования рецептур обоснованы стремительным ростом популярности продукции растительного происхождения. Безмолочные белковые напитки и десерты сформировали существенную потребительскую нишу, стали обязательной частью диеты современных потребителей не только комплементарно или в качестве перекуса, но и в качестве отдельного полноценного приема пищи, что формирует устойчивые привычки здорового пищевого поведения. Nutritional habits and needs for nutrients develop throughout a person's life under the influence of various factors, but the fact of the body's biological need for essential amino acids, and as a result, for accessible, complete proteins, remains undeniable. The search for new sources of protein and the development of technologies for its production, reproduction, processing, saving are always in the center of attention of the food industry. The demand of the growing world population for affordable food resources rich in complete protein only increases every year. The choice of the optimal formula, processing method or combination of a composition of natural proteins of plant origin, capable of acting as a renewable source of essential amino acids, in order to fully replace proteins of animal origin, and, in particular, dairy proteins, in accordance with the principles of economic feasibility, is the main driving force of research and development. The relevance of the review of raw materials and the formation of criteria for the selection of vegetable raw materials for the purpose of application in models for designing formulations is justified by the rapid growth in the popularity of products of vegetable origin. Dairy-free protein drinks and desserts have formed a significant consumer niche, have become an obligatory part of the diet of modern consumers, not only as a complementary or as a snack, but also as a separate full meal, which forms stable healthy eating habits.

Water-in-oil-in-water (W1/O/W2) emulsions are complex delivery systems for polyphenols amongst other bio-actives. To stabilize the oil–water interphase, dairy proteins are commonly employed, which are ideally replaced by other, more sustainable sources, such as insect proteins. In this study, lesser mealworm (Alphitobius diaperinus) protein concentrate (LMPC) is assessed and compared to whey protein (WPI) and pea protein (PPI), to stabilize W1/O/W2 emulsions and encapsulate a commercial polyphenol. The results show that LMPC is able to stabilize W1/O/W2 emulsions comparably to whey protein and pea protein when using a low-energy membrane emulsification system. The final droplet size (d4,3) is 7.4 μm and encapsulation efficiency is between 72 and 74%, regardless of the protein used. Under acidic conditions, the LMPC shows a similar performance to whey protein and outperforms pea protein. Under alkaline conditions, the three proteins perform similarly, while the LMPC-stabilized emulsions are less able to withstand osmotic pressure differences. The LMPC stabilized emulsions are also more prone to droplet coalescence after a freeze–thaw cycle than the WPI-stabilized ones, but they are the most stable when exposed to the highest temperatures tested (90 °C). The results show LMPC’s ability to stabilize multiple emulsions and encapsulate a polyphenol, which opens the door for application in foods.

Milk-containing products occupy a large place in the range of popular products. Replacing milk fat or protein with vegetable fat can reduce the biological value of the product and its organoleptic properties. the effect of direct application starter cultures on raw materials that use functionally necessary ingredients (structure-forming agents, salt, sugar, etc.), food additives (thickeners, stabilizers, preservatives, etc.) and a variety of non-dairy components (non-dairy fats, non-dairy proteins, meat products, fruits, vegetables, spices, herbs, nuts, etc.) is ambiguous. The paper deals with the use of homogeneous and combined starter cultures in the production of fermented milk products from natural and normalized milk and milk-containing mixtures with a substitute for milk fat. The introduction of components of plant origin into the product leads to a decrease in the content of milk protein in the mixtures, which in turn leads to the formation of clots with a non-uniform consistency. Slow acid formation in milk-containing mixtures indicates a decrease in milk sugar in them with this type of normalization in fat, relative to the normalized milk according to the classical technology. This pattern was revealed both when using starter cultures on lactic acid thermophilic streptococci, and on combined starter cultures. In this paper, it is proposed to use Streptococcus salivarius subsp in ferments for milk-containing mixtures. thermophilus strain ST-95. The introduction of the ST-95 strain into the starter culture made it possible to obtain from the milk-containing mixture a fermented milk product with well-pronounced organoleptic properties, a stable clot structure and sufficiently high taste properties. The greatest positive effect was obtained on combined ferments.

Meat and dairy products in the food industry represent a significant portion of anthropogenic green house gas emissions. To meet the Intergovernemental Panel on Climate Change recommendations to limit global warming, these emissions should go down. Meat and dairy products are also responsible for the majority of our daily, vital, protein intake. Yet, meat and dairy products contain very different amounts of proteins, making it difficult in general to rationalize which protein source has the lowest carbon footprint. Here we offer a practical and pedagogical review, comparing the carbon footprint of a variety of meat and dairy products with respect to their protein content. We report further on a number of consumer oriented questions (local or imported? organic or not? cow or goat milk? hard or soft cheese?). We investigate finally the carbon footprint of different dietary choices for several countries, by keeping the total number of meat and dairy proteins constant. Dairy-only diets are in general a little less carbon intensive than current diets; while up to 60% lower carbon footprint diets can be achieved by eating for only part poultry, small animals and yogurt. Our assembled data is readily available through an open source app allowing to investigate personalized dietary scenarios. We expect our results to help consumers perform enlightened carbon footprint dietary choices. Our methodology may be applied to broader questions, such as the carbon footprint of proteins in general (including fish and plant proteins). We hope our work will drive more studies focusing on consumer-oriented questions.
