The paper presents the results of a study of indicators that characterize the nutritional and biological value of new functional products-canned minced thorny skate with the addition of Atlantic cod – «Meatballs of stingray and cod in tomato sauce» and «Thorny skate and cod in white sauce». The content of 100 g of the product of the main food nutrients, namely, protein – from 8.4 to 10.0 g, fat – from 2.6 to 6.7 g, carbohydrates – from 10.2 to 18.1 g, depending on the recipe, was experimentally established. Studies have confirmed the high content of minor food substance – chondroitin sulfate (CS) – in canned thorny skate from 250 to 270 mg per 100 g of the product, which provides the recommended level of adequate consumption from 35.7 to 38.6%. On the basis of experimental data on the amino acid composition of the protein of new products, the indicators characterizing the biological value are calculated. Based on the results of the study, a reasonable conclusion was made about the high nutritional value and the presence of functional properties in canned thorny skate with the addition of Atlantic cod.
