FIELD: chemistry. n SUBSTANCE: invention relates to microbiological industry and technology, namely, to biologically active additives based on dairy raw materials and selenium. Invention includes preparation of nutritional medium based on cleared curd serum, introduction of 15-20 mkg/ml of sodium selenite and inoculant, and cultivation. As inoculant activated cultures of bifidobacteria Bifidobacterium longum strain B 379 M or propiono-acid bacteria Propionibacterium freudenreichii subsp. shermanu strain KM 186 are used. n EFFECT: production of probiotic selenium-enriched biologically active additives, which have polyfunctional properties; increased anti-mutagenic activity of microorganisms; greater amount of exopolysaccharides in the product; enhanced bioavailability of selenium. n 3 dwg, 3 tbl, 4 ex |
