Objective of the study was to assess the nutritional value and functional properties of the developed dry concentrates of carbohydrate-protein beverages based on vegetable feedstock as a special diet for athletes.
Methods and structure of the study. Organoleptic, physical-chemical, and microbiological studies were conducted using standard and original methods, mathematical modeling, and statistical processing of experimental data. The study material was: common pine-nut (Pínus sylvéstris) oil meal, pine-nut solvent cake meal, dried Siberian rowanberry (Sorbus sibirica) and Prickly wild rose (Rósa. culaciáris), powders from the mentioned fruit and berry raw material, dry non-fat milk, stevioside, corn starch, experimental samples of dry concentrates of functional carbohydrate-protein beverages from vegetable feedstock and samples of prepared beverages on their basis with a hydraulic module of 1:10 for special diets for athletes.
Results and conclusions. We confirmed the enrichment of new dry carbohydrate-protein concentrates and prepared beverages with biologically active substances; proved that functional beverages based on dry carbohydrate-protein concentrates from vegetable feedstock should be included in sports nutrition to rapidly restore athletes' need for basic foodstuffs and improve their endurance, adaptability, and athletic performance. The development of dry carbohydrate-protein concentrates using new raw materials provides an opportunity to contribute to the development of food technologies in sports nutrition sphere.

Keywords: compositions of dry concentrates of functional beverages, pine-nut solvent cake meal, powders from dried rye fruit of Siberian and Prickly wild rose, stevioside, sports nutrition.
