Abstract

The effect of polysaccharide thickeners - xanthan and guar gum - on the colony-forming ability of probiotic microorganisms of the species Lactobacillus acіdophilus (LA-5) was investigated. The spectrum of inorganic salts, which in the given media can be a source of free calcium ions for further Lactobacillus acidophilus encapsulation in shells based on sodium alginate was considered. According to the results of microbiological studies, it was found that the polysaccharide components do not reduce the activity of the probiotic microorganisms, and inorganic salts introduced in concentrations that provide an osmotic pressure on the Lactobacillus acidophilus cells, inhibit metabolism processes. Based on the data obtained, qualitative and quantitative composition of the medium, the components of which do not reduce the viability of microorganisms and contribute to the encapsulation process for increasing the shelf life of food products based on the systems considered was determined.
