Abstract
Nutrition is one of the fundamental factors of human health. Today the use of biologically active food additives, enrichment of products with nutraceuticals, consumption of target foods is justified due to the increasing effect of stress along with unbalanced diet and lifestyle. The main resource of nutrients is plant foods and substances derived from them. The use of additional plant components in the manufacture of food products contributes to increasing its biological and nutritional value. Non-traditional plant species have a high potential along with traditional crops. A lot of research is aimed at identifying the positive effects of bioactive substances of plants on the body and the possibility of using them to expand the range of useful food products. We investigated the prebiotic properties of the underground part of plants from the Brassicaceae family. In the course of the study we applied traditional microbiological methods of research. As the results of the experiments showed, the plant extracts promoted the growth of lactobacilli, and the prebiotic activity was not inferior to the common preparations - lactulose. The obtained data will be used for further research for the development of technology for obtaining products with a positive effect on the normoflora of the intestine and implying the inclusion of prebiotic substances in the formulation.
