摘要：Our experimental research revealed that in order to improve consistency during storage of sour milk beverages, it is necessary to ensure the binding of free moisture through the use of natural stabilizers, thickeners and the substances that perform a similar function. Among many tested ingredients of this group of substances, the stabilizing systems based on natural components of plant and animal origin were selected for implementation and preferred for usage. Analysis of the information sources shows lack of data on the use of wheat bran in the technologies of sour milk beverages. That is why there is an objective need to create new kinds of sour milk beverages, specifically, kefir with the use of wheat bran. Consumption of such functional products guarantees the elimination of malnutrition, replenishment of the organism with necessary components.The influence of wheat bran on quality indicators of the sour milk beverage was studied. It was found that the sour milk drink with wheat bran with fat content of 2.5 % by physical and chemical indicators meets the requirements of standard DSTU 4417:2005. Kefir. Technical specifications. Studying the organoleptic indicators of the beverage using wheat bran revealed its clean sour milk taste and smell. The total amount of amino acids in the drink with wheat bran increased by 15.08 %, the amount of essential amino acids – by 10.57 %, and that of nonessential amino acids – by 18.24 %. The identified changes in the amino acid composition of the drink with wheat bran indicate that the use of wheat bran in manufacturing sour milk beverages allows increasing their nutritional and biological value of the protein component.The sour milk drink with wheat bran is a medical and prophylactic product because it contains dietary fibers, which are a valuable energy additive.
