Intensification of malting using bioregulation.Peer-reviewed article

V. TODOROVÁ

The author observed changes of cytolytic modification during a germination of barley using the following bioregulators: indoyl-3-acetic acid (heteroauxin), IOK, the complex enzyme preparate containing α-amylase and β-glucanase and the complex enzyme preparate B with proteolytic activity without amylolytic and cytolytic activities. In the concentration used the IOK preparate accelerated cytolysis of a barley germination and stimulated protein splitting. No effect on the content of α-amylase was observed. A small increase of diastatic power. The complex enzyme preparate A added supported cytolysis and increased α-amylolytic activity and diastatic power. The complex enzyme preparate B had no effect on cytolytic modification. Its application increased the content of nitrogen compounds to the optimum value for brewing aims. The results obtained on the laboratory scale were confirmed on the large scale. The positive effect of the enzyme preparate A was found in the decrease content of polyphenols in beer and the increased content of amino acids besides proline, methionine and thyrosine. The economy of malting intensification resulted in a shortening of production cycle.
