The relevance of research is the experimental and analytical justification of the effectiveness of the joint use of biopolymers of animal and plant origin as a substrate in the process of immobilization of the association of probiotic cultures. Researches are executed in specialized laboratories of universities: Omsk GAU, Saratov GAU, SKFU. In the form of a substrate were used: gelatin, χ-carrageenan, low-esterified pectin, modified starch; as bioobjects are selected: L. acidophilus, B. Lactis, S. thermophilus. To obtain reliable and complete characteristics, a set of research methods was used in the work: physicochemical, sensory, and microbiological. Investigation of immobilization allowed to determine the optimal ratio of biopolymers as a carrier (substrate): pectin and gelatin, as 2:1; the total concentration of solids of the carrier solution (20.0 ± 0.5)% by weight. The total number of viable cells of probiotic microorganisms in membranes (plates) is an average of lg (11.0 ± 0.55). In order to extend the shelf life, the membranes were dried in a freeze dryer, with parameters: the temperature of the frozen product (-25 °C) and the residual pressure in the sublimate 0.013-0.133 kPa.
