Prospects of innovative functional foods based on biologically active dietary supplement (Bads) "Vitazar"

The development of syn- and metabiotics is one of the most important technological lines of reserch in the production of functional foods. The positive effect of these products is achieved by the addition of enrichment components into the formulations that provide selective stimulation of the of intestinal normal flora's growth or activates it's metabolic activity. In this regard, scientific and practical interest seem to study the possibility of expanding the range of synbiotic products containing not less than107 CFU / ml of the probiotic microorganisms on the dairy, vegetable-dairy (protein-free milk), or only on the plant-based medium without dairy ingredients. In the research work we have studied the conditions for the accumulation of biomass of probiotic microorganisms consortium, consisting of L. casei subsp. Rhamnosus, L. acidophilus, L. plantarum, L. fermentum, Bifidobacterium bifidum, Bifidobacterium longum, Bifidobacterium adolescentis on nutrient mediums containing 1-20 % wheat germ flour "Vitazar". The quantitative assessment of the accumulation of probiotic microflora biomass and its metabolites in milk-vitazar based, whey- vitazar based, water-vitazar based nutrient mediums has been carried out. The concentration of Lactobacterium and Bifidobacterium in active form in quantity of 109 CFU / ml has been reached. It was found out that "Vitazar", being a source of dietary fibers and a wide range of carbohydrates, is capable to support the growth of Lactobacterium and Bifidobacterium, forming the favorable environment. The accumulation of probiotic microflora has been observed by the increasing of titratable acidity due to lactose fermentation by β-galactosidase, produced by microorganisms of the consortium. The main stages of the process of the accumulation microbiomass have been identified in the study of the kinetics of the fermentation process. The derived fermented pastes, containing 20 % and 30 % "Vitazar" are recommended as a component of formulations of functional products.
