Recently, sugar maize has become more and more widely used for the production of new types of food. Its use in the production of cereal products for babies makes it possible to use no sugar in their composition, switch to the production of dietary and prophylactic products, which acquires high importance against the background of “rejuvenation” of diabetes and the manifestation of other nutritional diseases. To enhance the consumer properties of the finished product, to give it the appropriate taste, colour and aroma, as well as to enrich with vitamins, mineral components, flavonoids, phytoncides and glucosides, the following raw materials were selected as the main components for their preparation: maize grains, hullless barley grains in the ratio 1:1, liquorice root (2–4%), carrot roots (2–4%). The article presents the results of microbiota studies of extruded grain products with plant additives during storage. The obtained samples were stored in the laboratory in polypropylene, plastic packaging and cardboard boxes at room temperature of the air +(15–20)°C and air humidity 60–75%. The obtained results allow us to establish that with prolonged storage of commercial samples of extruded grain products with the inclusion of vegetable additives in different temperature and humidity conditions, as the shelf life increases, the number of bacteria decreases. The absolute number of spore-forming bacteria in the samples under study, which were stored in synthetic packaging, remained at the same level, and their relative content in the total bacterial flora increased. On the basis of the research, it has been established that the enrichment of products extruded from sugar maize grain with vegetable additives does not impair their microbiological and physico-chemical characteristics during long-term storage in unregulated conditions. It also allows expanding the range of this type of products.
