Abstract

Innovations in the agro-industrial sector are determined by the development of biotechnologies from the stage of growing raw materials to their processing and storage. In compliance with the phytosanitary requirements (including the use of radiation technologies) for grain, the issues of ensuring the preservation of dry composite mixtures are determined by the storage conditions and the use of bitechnological techniques for prolonging the shelf life when adding phytosources with antimicrobial action to them. The addition of nettle, Echinacea purpurea, sage and oak bark to mixtures consisting of 87.5% rye seed and extrusion flour and wheat flour of the first grade in an amount of 0.1% of the prescription composition made it possible to ensure compliance of such organoleptic indicators as color, whiteness and smell with the requirements of regulatory documents and to reduce microbiological contamination, as the most important factor in extending the shelf life, by 1.2-2.0 times up to 7-12 months. compared to the control samples. Echinacea purpurea has the greatest fungicidal effect, followed in descending order by sage, oak bark and nettle. The results obtained are of practical significance for the application of gentle biotechnologies in the production of dry composite mixtures.
