The effect of enzymes of proteolytic action on the amino acid composition of the filtrate and grains of grain wort obtained from UDA-treated rye was studied. The feasibility of using a complex of proteolytic enzymes: neutral and acid proteases is shown. The processing of rye was carried out on the disintegrator DEZI15 with different working elements: three and five-row rotors rotating at a frequency of 120 s1. A control sample of grinding was obtained in a laboratory mill with a rotor-knife working body. According to the data obtained on the Malvern Mastersizer 2000 laser analyzer, the average particle size in the grinding samples was: on a disintegrator with a three-row rotor - 167.5 microns, on a five-row rotor-knife working body - 384.278 microns. As a source of proteolytic enzymes, preparations of the fungal protease Рrо100L and the bacterial protease Protosubtilin GZх A120 were used. The determination of the content of ?-amino nitrogen in the finished wort (mg / dm3) was performed by calorimetry with ninhydrin...
