Complex enzyme and use thereof

Abstract

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.

Description

Technical field: [0001] The invention relates to the field of bioengineering and belongs to liquor brewing technology, in particular to a compound enzyme suitable for producing Xiaoqu liquor with wheat as raw material and its application. Background technique: [0002] Xiaoqu baijiu is one of the main wines in my country, and its annual output accounts for more than 30% of the total liquor output. It is mainly produced in the south and southwest of China. The production of Xiaoqu baijiu mainly uses sorghum, corn, wheat, barley, etc. as raw materials, uses Xiaoqu as a saccharification starter, uses whole-grain raw material cooking, box-type solid-state culture for saccharification, fermented grains with fermented grains, and solid-state distillation. At present, the saccharification starter used in the production of Xiaoqu Baijiu is mainly Rhizopus yeast Sanqu. The production method is that the pure rhizopus and yeast are separately inoculated on the bran and then mixed and ...

AI Technical Summary

Problems solved by technology

And because each production factory of Rhizopus yeast Sanqu has different technical levels, the produced Rhizopus yeast Sanqu has shortcomings such as saccharification power, low fermentability, and miscellaneous bacteria, and the amount of addition is also relatively large (0.5%- 1%)

Therefore, it cannot bring good economic benefits to the enterprise.
