Abstract. The development of specialized sports nutrition with components of collagen-containing fish raw materials is due to the shortage of domestic products of this group, the problem of fish waste processing, scientific data on bioactive peptides of marine origin. Low-molecular active peptides and protein-mineral compositions in the form of powder and liquid dietary supplements were obtained from the scales of sardine and sardinella by methods of deep hydrolysis. During the hydrolysis of raw materials, fermentolysis was carried out with the Alcalase 2.5L enzyme, thermohydrolysis – at temperatures of 130–140 °C. The chemical composition of the scales of two fish species, the products of its hydrolysis, and the amino acid composition of its proteins have been studied. The amount of low-molecular-weight peptides in hydrolysates of sardine scales was investigated by various methods of hydrolysis. Rational methods of hydrolysis of scales – enzymatic and enzymatic-thermal – have been substantiated. They make it possible to obtain protein supplements with protein content of 83.9–85.2 % with a proportion of active peptides with a molecular weight of less than 10 kDa 91.7–98.1 %. A technology for obtaining protein supplements from fish scales has been developed, and their amino acid composition has been studied. The presence of irreplaceable and ergogenic amino acids, accompanying nitrogenous compounds, valuable in sports nutrition, was shown in the peptide supplement. An increased content of calcium, phosphorus and magnesium in the protein-mineral dietary supplement being important for the musculoskeletal tissues of an athlete has been established. On the basis of protein supplements in dry and liquid forms with the addition of beekeeping products, the technology of chewing marmalade for sports nutrition has been developed. Bioproduct "Apikolltonus" belongs to the class of gainers with a protein content of 20.5 %, a carbohydrate of 41.6 % with an amino acid value of BCAA (isoleucine : leucine : valine) 2 : 1 : 1.5. A multicomponent bar for sports nutrition has been developed using protein hydrolysates of scales, flaxseed and apple cakes, and pine nuts. The bar is functional in terms of the content of calcium and phosphorus, dietary fiber, flavonoids, and vitamin E. Recommendations for the use of new sports nutrition products are substantiated.
