Development of Dry Mixtures for Protein-Carbohydrate Drinks Used for Sports Nutrition

Abstract

This work is aimed at developing mixtures of protein-carbohydrate drinks used in sports nutrition. Specialized protein-carbohydrate products are the powdered food mixtures with a high content of proteins and carbohydrates required for maintaining and increasing the muscle mass, restoring the glycogen levels in the muscles and the liver, and for correcting the diet of an athlete. At the first stage, theoretical work was carried out aimed at the generalization and analysis of scientific literature. Based on the literature review, biomedical and technological requirements for specialized protein-carbohydrate products for the nutrition of athletes were systematized. In accordance with the requirements, the components (Fonterra WPC 80 protein, skim milk, fructose, cocoa powder, egg albumin, maltodextrin, thickener, natural dyes, flavoring substances) were selected and justified, and the formulation of the developed products was calculated. Further research was aimed at studying the influence of product components and technological factors on the physicochemical properties of carbohydrates and proteins in the model "protein-polysaccharide-water" system. Calculation of the biological value of protein preparations was conducted, as well as the experimental studies of the dry mixing technology aimed at selecting the sequence of the introduction of components for the production of dry multi-component specialized products. Based on theoretical studies and generalizations, technological requirements and modes have been specified, and the technology of dry mixtures of protein-carbohydrate drinks for sports nutrition has been developed. Product optimization, its physicochemical, and organoleptic studies have allowed developing draft technical documentation for dry mixtures of protein-carbohydrate drinks for sports nutrition.
