GROWTH STIMULATORS IN MALT PRODUCTION TECHNOLOGIES

This study focuses on the use of the growth stimulator “Energen” in barley malt production to accelerate biochemical processes. The experiment was conducted on “Vorsinsky 2” barley treated with “Energen” at a concentration of 0.6 g/dm³. The results demonstrated an increase in amylolytic activity from 345.9 to 432.2 units/g and proteolytic activity from 68.9 to 94.6 units/g. This facilitated the improved hydrolysis of carbohydrates and proteins and increased malt extractivity to 83.2 %. The application of the preparation reduced the saccharification duration of laboratory wort from 18 to 15 minutes. The high enzymatic activity enables the use of malt with hard-to-dissolve raw materials and eliminates the need for corrective measures. The method is also recommended for barley with a high protein content, as the accumulated enzymes ensure proteolysis to regulatory values. Thus, the stimulation of biochemical processes with “Energen” improves the technological and quality indicators of malt, optimizing its production process.
