Разработка комплексной технологии переработки органических отходов рыбоперерабатывающих предприятий на коллагенсодержащие гидролизаты пищевого назначения

Abstract

Recently, there has been a problem associated with the limited resources of animal protein, in this regard, one of the promising directions is the effective and rational use of raw materials of animal origin, improvement of methods of its processing, storage and transportation, as well as the introduction of resource-saving and waste-free technologies. Technologies that allow the maximum use of natural raw materials are particularly developed. The paper investigates the issues of rational use in the food industry of organic fish processing plants - fish skin containing valuable protein - collagen, and proposes a technology for producing collagen-containing hydrolysates on its basis, due to biotechnological treatment with the enzyme preparation “Collagenase” together with a solution of citric acid and subsequent sublimation drying. The results of the assessment of the quality level of collagen-containing hydrolysates from the skin of sockeye (Oncorhynchus nerka), cod (Gadus morhua) and chum (Oncorhynchus keta) are presented. The developed technology makes it possible to obtain hydro-lysates with higher organoleptic characteristics with the content of collagen fiber fragments, which can be used as structure-forming agents in the production of food products.
