CONSUMER PROPERTIES OF STRUCTURE FORMING SUBSTANCES BASED ON SECONDARY RAW FISH WITH CYSTOSEIRA

The feasibility and effectiveness of integrated processing of inland fish are substantiated in the work. The present state, innovative developments of domestic and foreign scientists are analyzed, perspective directions of complex processing of fishery raw materials and development of market of structure forming substances are determined. It is theoretically substantiated and experimentally confirmed the expediency and efficiency of the use of secondary fishery raw materials from silver carp (heads, bones, fins) in order to form the consumption properties of the structure forming substances. Experimental studies using mathematical modeling methods have optimized the ingredient composition of structure forming substances. The regularities of the formation and stabilization of the consumption properties of structure forming substances based on the secondary fishery of silver carp by introducing cystoseira (2 %) into their composition are scientifically substantiated. The optimal ratio of fish waste to water was set to 1: 1.5; time of fish broth heat treatment - 2.5 hours at 85 - 100ºС; freeze drying temperature (50 – 70 ºC). The consumption properties of the structure forming substances have been investigated, and regularities of changes in quality indicators in the process of their storage have been determined. The results of studies of the amino acid composition of the finished structure forming substances are presented. Research has found the highest content of the following amino acids: glycine, alanine, proline, aspartic and glutamic acids. These amino acids form a repeating sequence in the polypeptide chain, causing the helical structure of collagen. High content of glycine and glutamic acid in the experimental structure forming substances is a characteristic feature of the amino acid composition of fish collagen. Fewer amino acids, such as histidine, isoleucine, valine, may be due to fewer cross-links. The dynamics of dissolution of structure forming substances within 15 months were investigated to ensure the guarantee shelf life. The results of the studies showed almost twice as fast the dissolution time of the experimental structure forming substances on the basis of the secondary fish raw material compared to the control, which can be explained by the peculiarities of the collagen structure. The number of mesophilic aerobic and facultative anaerobic microorganisms (KMAFanM), the presence of E. coli bacteria and pathogenic microorganisms, including the Salmonella genus, were determined
