The results of the studies indicate an increase in the efficiency of enzymatic hydrolysis of wheat grain subjected to infrared irradiation in the production of feed molasses. It was found that the duration of enzymatic hydrolysis of grain to significant concentrations of sugars in feed molasses is reduced by 2 times and energy costs are reduced by 40 %, and the concentration of sugars increases at the end of the process by 4.0 % compared to existing technologies.
