Domestic developments of protein systems such as "Collagen" for solving the problems of industrial import substitution

Introduction. In the context of solving the protein problem, technological solutions for the rational use of protein resources of animal origin in the food industry, public catering, and the primary processing of raw materials of animal origin are presented, which are extremely relevant for the agro industrial complex of the Russian Federation in the conditions of a turbulent market and new geopolitical realities. There is a long overdue need for sectoral import substitution in industries processing raw materials of animal origin, in the meat industry, etc. Domestic scientific developments can be used to replace imported dietary supplements, protein supplements, products with the trademark "Collagen", etc.

Purpose. To study the structure and properties of protein systems based on complex biopolymers and to form recommendations for the introduction of domestic developments that have been actively developed in universities and research institutes for 30-40 years.

Research materials. Protein systems based on fibrous proteins, biologically active protein additives "Collagens".

Materials and Methods. To achieve this goal, samples of protein systems based on fibrous proteins obtained in the laboratory by the method of controlled hydrolysis, as well as biologically active protein supplements of the Collagen trademark, were used as an object of testing. The study of rheological, microstructural and other properties was carried out by the following methods: rotational viscometry, optical microscopy, scanning electron microscopy (Coxem), elemental microanalysis, mathematical data processing with calculation of standard deviations, graphical approximation of test data by standard software.

Results. New data on the structure, physical, including rheological and chemical properties of protein systems have been obtained. In particular, the rheograms testified to the nonlinear behavior of the systems, which allows them to be attributed to pseudoplastic colloids. The elemental composition of individual protein systems was analyzed, which revealed the presence of trace elements (due to the influence of the raw material factor), the functions in vivo are not fully elucidated.

Conclusions. The ways of solving the problem of complex, fiber-forming biopolymers are substantiated, new data on the structure and properties of raw materials and animal products are obtained, practical recommendations for early application (under the import substitution program) in biotechnology, food production, meat industry, animal raw materials processing enterprises are highlighted.
