During the microbiological control of functional foodstuffs, it was determined that drinkable yogurts such as
Activia, Imunele, and Dannon contain living lactobacilli and bifidobacteria in the amount of 107 CFU/ml. In the
children's porridge Pomogayka, bifidobacteria are found at a titre of 106 CFU/g. The content of probiotic bacteria in
these products fully meet their quantity indicated on the product label. The identification by culture-morphological,
physiological and biochemical characteristics supports that selected isolates belong to the Lactobacillus
Bifidobacterium genus. It is identified that the survival rate of test-strains cultured with pasteurized products is not
more than 10% different from the control ones. Most antagonistic activity has a probiotic product Activia.
