Abstract
Biocorrectors are dry concentrates from natural raw sources with high nutritional value due to the high content of important chemical components of food, including essential, minor, and biologically active nutrients. The raw material for the production of natural biocorrectors can be waste from cutting the fish and animal products. It is promising to use the skin of an octopus, the weight of which during cutting is up to 37% of the weight of raw materials, Pacific herring milt, which is formed during cutting in an amount of up to 12.4% of the weight of raw materials, and bivalve mantle mollusk of Primorsky scallop, accounting for about 10% of its mass. The goal of the research is to obtain dry food concentrates from seafood waste that exhibit functional properties. To preserve and form the specific properties of finished products, namely high biological value, digestibility, organoleptic indicators of concentrates, low-processing temperatures (cryotechnology) were used, which maximally preserved the composition, structure and other natural properties of raw materials. The dry seafood concentrates obtained by cryogenic technology exhibit high functionality and can be used as biocorrectors of food in order to impart high nutritional and biological value to it due to the balance of microand macronutrients.
Highlights
Modern research and development are aimed at creating the technologies for concentrates of natural products from raw materials containing essential, minor, and biologically active food substances
Based on the results of the analysis of technologies for obtaining the cryopowders from vegetable raw materials [7,17,18], we have proposed a structural technological scheme for the cryoprocessing the seafood in order to produce dry finely dispersed concentrates from them (Fig. 2)
Raw materials are supplied for processing in frozen form, its temperature is about - 18°С
Summary
Modern research and development are aimed at creating the technologies for concentrates of natural products from raw materials containing essential, minor, and biologically active food substances. Concentrates are used as a basis for obtaining a variety of instant products or food biocorrectors in order to give it a balance of micro- and macronutrients, high quality and biological value. The main direction of using the waste from cutting the fish and seafood is associated with the production of a variety of feed products, primarily feed flour. Products obtained from secondary raw materials, as a rule, are of insufficient quality, due to the high-temperature effect on raw materials, have a relatively high cost, since the technologies for their production are energy-intensive, while they have an unfavorable effect on the environment
