Found that the hydrolysis of whey proteins can be carried out by the action of chemical agents (alkali, acid) or enzyme preparations. However, the greatest interest is the enzymatic hydrolysis, which allows to obtain hydrolysates with desired properties. The advantage of the enzymatic hydrolysis of whey protein is a high speed under relatively mild conditions: atmospheric pressure and a temperature not exceeding 50°C. As a result of enzymatic hydrolysis is practically no destruction of amino acids and reducing the biological value of the end product. Depending on the content of amino acids, the molecular weight of the polypeptide fraction, presence of di-, tri-, and oligopeptides can be defi ned region of the most effective use of hydrolysates. Hydrolyzed whey protein is added to the confectionery and bakery products, products of the meat industry, they are a part of sports drinks and breast milk substitutes due to its high nutritional value, the absence of bitterness and low antigenic properties Feature of the proteolytic enzymes is their specifi city in relation to the type of the peptide bond, which allows to obtain hydrolysates with different degrees of hydrolysis of the protein, which are used in bakery, dairy and other industries.
