Currently, the development of rational technologies for processing secondary resources of the fish processing industry is of considerable interest in order to obtain a wide range of food, feed, technical, medical products and biologically active additives on their basis. Of particular interest is the technology developed by the authors for obtaining dry food fermentolizates from secondary products of cutting pink salmon and silver carp. In the course of the experiment, it was found that the protein zones for the samples are mainly represented by low-molecular weight easily digestible proteins with m. m. from 13 to 33 kDa. The evaluation of the ratio of amino acids compared to the FAO standard showed that in the human body, the amino acids of fermentolizates are able to be utilized by 68-80%, which proves their high biological value. Own experimental data indicate a high availability and degree of destruction of proteins of fermentolizates by enzymes of the human gastrointestinal tract, which is from 92.39 to 96.87%. Thus, fermentopathy from secondary cuts of fish are high-value protein products.
