Abstract

The invention relates to application of a strain of trichoderma reesei to barley malt production. The trichoderma reesei CICC41495 is used for treating Jiangsu barley malt; the content of high-molecular-weight arabinoxylan in the agreement wort of the treated barley malt is reduced from 876 mg / L to 235 mg / L, and is reduced by 73.2 percent; the viscosity is reduced from 1.59 mPa.s to 1.43 mPa.s, and is reduced by 10.1 percent; and the filtering speed is accelerated from 3.5 mL / min to 6.2mL / min, and is improved by 77 percent. The method provided by the invention has the advantages that by usingthe barley sprouting environment conditions, the trichoderma reesei grows on the surface of the barley; meanwhile, an araboxylan degrading enzyme system is secreted; the degradation of the high-molecular-weight arabinoxylan in the Jiangsu barley malt is promoted; the filtering speed of the agreement wort of the Jiangsu barley malt is accelerated; and conventional physicochemical indexes reach thelevel of first-grade products in the industrial standard QB / T 1686-2008.

Description

technical field

[0001] The invention relates to the application of a strain of Trichoderma reesei in barley malt production and belongs to the technical field of malt production. Background technique

[0002] In beer saccharification production, the saccharification mash is separated through the filter tank to obtain transparent and clear wort, and the separation speed of the wort in the saccharification mash is the filtration speed. The filtration rate of barley malt has an important influence on the beer production efficiency and the quality of finished beer. Therefore, the filtration rate of wort is one of the most important indicators for brewers, which determines the efficiency of the beer production process. Some studies have found that the arabinoxylan in the milk cell wall affects the filtration speed. Due to the high viscosity of high molecular weight arabinoxylan aqueous solution, the filtration speed of barley malt is slow, and the viscosity of saccharification i...
