Technology and equipment of food production 15 was formed. According to scientific research, functional foods include products that have a beneficial effect on human health if consumed regularly at effective doses. Such products contain functional ingredients that exert a biologically significant positive effect on the human body, which helps to adapt to environmental influences, prevent diseases and early aging [3]. The main types of functional ingredients include dietary fiber (soluble and insoluble), vitamins (A, E, B, etc.), minerals (such as Ca, Fe, I, Se), lipids containing unsaturated fatty acids (ω 3 , ω 6), antioxidants, oligosaccharides (as a substrate for beneficial bacteria), some types of beneficial microorganisms (bifidobacteria, etc.). From a medical, biological and hygienic point of view, the content of functional ingredients in food should be sufficient for providing 20-50 % of the average daily need of the body in these ingredients. But this is ensured with the usual level of product use. In special-purpose products, this content may be higher [4]. Along with functional ingredients, the enrichment of food with high-grade proteins is important. Protein in the human body can only be formed from the protein of food. The average standard daily physiological norm of protein for
