Nowadays, the use of plant components in terms of their pronounced functional properties is of high relevance. Oat extract contains gums, β–glucans, vitamins (A, B1, B5, B9, PP, H), minerals (Fe, I, K, Si, Mn, Cu, Mo, etc.) and essential amino acids. It has been proven that a long–term use of β–glucans showed the reduction of the risk of cardiovascular disease and diabetes and the regulation of cholesterol and blood sugar. β glucans also have immunoprotective, anti–inflammatory, antimicrobial, prebiotic effects and improve intestinal motility. The aim of study was to develop the technology of low–fat high–protein fermented milk product with functional characteristics. Oat extract was used as a natural stabilizer and a source of β–glucans. Maceration technique was used for the extraction. The recommended extraction parameters were established and physicochemical characteristics of the extract were studied. The recommended doses of oat extract when introduced into milk and the optimal heat treatment conditions of the milk–oat mixture were determined. The influence of temperature on the gel–forming properties of oat extract was investigated. The effect of oat extract on rheological behavior, water–holding ability and shelf life of the finished product was studied. Regular consumption of lactic acid microorganisms has a positive effect on the digestive system and metabolism. Based on the organoleptic characteristics and physicochemical changes during the fermentation process in comparison with the control sample (without oat extract), the recommended starter culture combinations (Lactobacillus acidophilus, Lactococcus lactis subsp, Lactobacillus bulgaricus) were proposed.
