Embodiment 1

[0020] The weight percent of each component of the enzyme composition is: 11% of amylase, 55% of protease, 18% of beta-glucanase, 9% of xylanase and 7% of corn starch.

[0021] The preparation method: the raw material enzymes are sieved respectively, and then put into an automatic mixing tank for compounding according to the proportion, and then packaged to become a product.

Embodiment 2

[0023] The weight percentage of each component of the preparation enzyme composition is: 4% of amylase, 33% of protease, 13% of beta-glucanase, 3% of xylanase and 47% of corn starch.

[0024] The preparation method is the same as in Example 1.

Embodiment 3

[0026] The weight percentage of each component of the preparation enzyme composition is: 9% of amylase, 50% of protease, 16% of beta-glucanase, 6% of xylanase and 19% of corn starch.

[0027] The preparation method is the same as in Example 1.

Abstract

The invention discloses an enzyme composition which comprises the components based on the weight percentage: 5-10% of amylase, 30-50% of prolease, 13-18% of beta-dextranase, 3-9% of xylanase and the rest of corn starch. The invention also discloses the application of the enzyme composition in brewage, and the enzyme composition is dissolved in the water in the saccharification stage of brewage; the enzyme composition solution and raw materials are fed together when in saccharification. The enzyme composition can effectively decompose pentosan and beta-glucan, improve the filter performance of wort and beer, increase the utilization rate of the equipment in brewhouse and reduce the energy consumption of production. By adding the enzyme composition of the invention, the content of the pentosan, protein and the beta-glucan in the wort can be effectively reduced, the quality of the wort is improved, and the malt part of wheat can be used for brewing beer instead of the malt of barley.

Description

technical field [0001] The invention relates to an enzyme composition and its application, in particular to an enzyme composition and its application for brewing beer, and belongs to the field of bioengineering. Background technique [0002] Beer brewing is the process of decomposing high-molecular insoluble substances in raw and auxiliary materials into soluble low-molecular substances by using malt's own enzymes or external enzymes, and adding yeast to ferment to obtain beverage wine containing a small amount of alcohol, carbon dioxide and various nutrients. The main raw material used in beer brewing is barley malt. However, due to continuous barley harvest failures in recent years, the price of barley malt has soared and procurement is difficult. Some beer manufacturers use wheat malt instead of barley malt to brew beer. [0003] Wheat malt has excellent brewing properties and has potential advantages in brewing beer. Wheat is widely planted in my country, with high yiel...
