Study of the stability of the main indicators of probiotic cultures Lactobacillus рlantarum No. 7 and Bifidobacterium adolescentis no. 17 in the bacterial mixture during storage

Abstract

The article presents the results of studying the stability of the main indicators of probiotic cultures Lactobacillus plantarum No. 7 and Bifidobacterium adolescentis No. 17 as part of a bacterial mixture during storage. The prebiotic component lactulose was added to the bacterial mixture at a concentration of 1.5%. The stability of the synbiotic bacterial mixture in vials and capsules when stored under appropriate conditions (in a place protected from light, at a temperature of 4–8°C) has been studied. Experiments have shown that the preservation of the liquid form of the bacterial mixture with the addition of a prebiotic component at a temperature of 4–8°C is possible for one month without a decrease in activity indicators, and for lyophilized form — for 12 months
