Justification of the quality of dry concentrates of functional protein-carbohydrate drinks for special nutrition of athletes

Abstract

The purpose is justification of the quality of dry concentrates of functional protein-carbohydrate drinks based on plant raw materials for specialized nutrition of athletes. The material for the study was cedar meal from Scots pine fruits (Latin Pínus sylvéstris), cedar meal flour, dried fruits of Siberian mountain ash (Latin Sorbus sibirica) and rose hips (Latin Rósa aciculáris), powders from the specified fruit and berry raw materials, skimmed milk powder, stevioside, corn starch, experimental samples of dry concentrates of functional protein-carbohydrate drinks from plant raw materials and samples of ready-made drinks based on them with a 1:10 hydromodule for special nutrition for athletes. Organoleptic, physicochemical, microbiological studies were carried out using standard and original methods, methods of mathematical modeling and statistical processing of experimental data were used. The combination of new compositions of dry concentrates of protein-carbohydrate drinks from vegetable raw materials for sports nutrition was formed; the quality of compositions of dry concentrates of new types of protein-carbohydrate drinks of functional purpose based on vegetable raw materials - flour from cedar meal, powders from dried fruits of mountain ash and rose hips with the addition of dry skim milk, stevioside, corn starch was justified. The research is promising in the creation of a range of dry concentrates of protein-carbohydrate drinks for sports nutrition using new types of raw materials, the advantage of which is naturalness and a significant content of functional ingredients. This makes it possible to contribute to the development of technologies for products for sports nutrition.
