Protein of fish origin – a source of health and beauty

This article is devoted to the study of collagen-containing raw materials and obtained collagen substances. Histomorphological analysis was carried out, which resulted in data on the presence of collagen in animal and fish raw materials, but characterized by a loose structure and a smaller thickness of fibers in the case of fish skins. Studies of the fractional composition showed that the predominant fraction is alkali-soluble, which include collagen proteins. The obtained dispersion of collagen fibers of the hides of inland water bodies and split leather from cattle hides. Dispersions are similar in properties, but have some differences associated with structural features. The materials obtained for the food, cosmetic and medical industries meet the principles of rational nature management and are economically viable.New ideas about the role of collagen in nutrition, the creation of original products, the need to develop unconventional and improve existing technologies of collagen substances of various functionalities, require the implementation of approaches to ensure maximum transformation of collagen-containing resources into human products, materials and tools.New ideas about the role of collagen in nutrition, the creation of original products, the need to develop unconventional and improve existing technologies of collagen substances of various functionalities, require the implementation of approaches to ensure maximum transformation of collagen-containing resources into human products, materials and tools.In terms of sanctions of the European Union, the United States and supporters, reducing the import of natural polymer-film coatings, finding new sources of film coatings for the food surface is most appropriate.
