The article presents research data that substantiate the relevance of the development of a ready-to-eat food product in the form of freeze-dried snacks and soups based on a homogenized fish-growing system. The developed recipe compositions and the technology of freeze-dried snacks and soups make it possible to produce high-protein, full-fledged amino acid products that also contain mono - and polyunsaturated fatty acids (omega-3,6,9), minerals (K, Na, P, Co, Cr, Se, I), nutritional fiber - fiber and inulin. High nutritional and biological values allow us to recommend the obtained freeze-dried products as functional food products for a wide range of consumers, including snacks for use in the diets of people who follow a "protein diet", as well as with increased physical activity; soups – for people with increased body weight, who monitor the calorie content of food, leading a healthy lifestyle.

In accordance with the Strategy for improving the quality of food products in the Russian Federation until 2030, the priority is scientific research in the field of nutrition of the population, including in the field of prevention of the most common non-infectious diseases and the development of production technologies aimed at improving the quality of food products, as well as promoting the principles of healthy nutrition. One of the ways to increase and promote them is the development of products containing immunomodulating components, which refers to promising areas for strengthening the immune defense of the human body. There are presented the formulations of finished food products (fish pates) containing components with immunomodulatory properties, such as fat-soluble vitamins A and D, Omega-3 polyunsaturated acids, copper (Cu) and the prebiotic inulin. Optimal formulations have been designed and the technology of the products has been developed. Analyses of the quality indicators of the developed finished products allowed us to establish its high nutritional, in particular biological value: semi-canned food contains fat-soluble vitamins A (386.50 - 443.31 mcg/100 g) and D (10.39 - 12.96 mcg/100 g), polyunsaturated fatty acids of the Omega-3 group (1.02 g - 1.35 g), essential microelement copper (0.86 - 1.21 mg/100 g), as well as dietary fibers, in particular inulin (3.12 - 3.49%), the amount of which will satisfy the daily physiological need by more than 15%, which allows to recommend them as natural functional food products with immunomodulating components.
