There are difficult climatic conditions and a deficiency in the diet of a number of vitamins – C, group B, A and minerals – iodine, selenium, fluorine, calcium in nine Arctic zone regions of the Russian Federation. The study aims at substantiating the composition and develop ing the technology of a complex food additive (CFA) of adaptogenic action for the Arctic zone population of the Russian Federation. Based on the chemical composition analysis of plant raw materials, its cost and availability, a man determined the composition of CFA with adaptogenic properties, including watermelon leaves, rosehip and hawthorn fruits, mead ow clover leaves, peppermint, wild strawberry, currant, buckwheat grass. The authors run the mathematical modeling of the optimal CFA formulation using the Pearson criterion; and calculated coefficients reflecting the calculated nutrient composition content of the five de veloped CFA formulations. The researchers improved the technology for obtaining CFA, con sisting in introducing an additional step for thermostating phospholipids to a temperature of 37 °C to obtain an emulsion without adding distilled water and reducing the melting point in the bioreactor to 70 °C. The obtained parameters of freeze drying of vegetable raw mate rials enable to remove moisture and preserve the entire nutrient composition. The research ers determined the necessary equipment, obtained the CFA samples in the form of a powder, being examined for uniformity and particle size. When a man introduced phospholipids, all the ingredients of a complex food additive are combined into a conglomerate contributing to the uniform distribution of nutrients over the volume of a functional food product.
