The invention relates to complex
enzyme and application thereof, which belongs to the technical field of the
brewing of distillate spirits. The complex
enzyme comprises the following
enzyme preparations and yeasts: 200 to 225 U / g of saccharifying enzyme (wheat), 80 to 100 IU / g of
pullulanase (wheat), 10 to 15 IU / g of acid
protease (wheat), 15 to 20 IU / g of
cellulose (wheat), 15 to 20 IU / g of beta-
dextranase (wheat), 5 to 10 IU / g of beta-mannase (wheat), 10 to 15 IU / g of
xylanase (wheat), 5 to 10 IU / g of
phytase (wheat), 5 to 10 IU / g of pectase (wheat), 1.5 to 2 percent of high temperature resistant
saccharomyces cerevisiae (W / W), and 1 to 1.5 percent of
aroma-producing
yeast (W / W). The complex enzyme is applied as an additive to the production of wheat type distillate spirits. The complex enzyme can increase
fermentable sugar, improve the
utilization rate of raw materials, and improve the
distillation yield; at the same time, the complex enzyme releases and synthesizes more
flavor substances, and has the advantages of improving the quality of the distilled spirits and increasing the high-quality product rate of xiaoqu distillate spirits and so on; and the complex enzyme can be widely applied to the production of wheat type distillate spirits.
