Abstract

A Daqu powder preparing process is disclosed. The process includes a) a step of raw material selection, namely a step of selecting large-grain full-grain insect-free damage-free wheat, pea, corn and red sorghum, cleaning and airing the raw materials and keeping the raw materials for later use; b) a step of grain moistening, namely a step of adding clear water into the raw materials, fully stirringthe mixture, and allowing the mixture to stand for 20-24 h; c) a step of crushing the moistened grains into particles having a size of 80 meshes; d) a step of adding water to the moistened grains, fully stirring the mixture, and spreading and airing the mixture at a constant temperature for 1-2 h; e) a step of stacking the moistened grains after spreading and airing, performing fermentation for 10-15 days, then drying the product and crushing the product into powder; and f) a step of mixing the prepared powder and aged Daqu powder according to a weight ratio of 1:1.5 to obtain the Daqu powder. The prepared Daqu powder has thin skin, full hyphae and strong Daqu fragrance, can improve fermentation capability and saccharifying capability of Jiuqu and can improve the liquor yield in liquor making.

Description

technical field [0001] The invention belongs to the technical field of brewing, and in particular relates to a preparation process of Daqu powder. Background technique [0002] Koji powder is the material needed for the production of distiller's yeast. In the ordinary preparation process, the selected materials are generally relatively simple, and the fermentation process is too simple. The koji powder mycelium prepared by this common preparation process is not full enough, and the koji fragrance is not strong enough. [0003] In addition, the koji produced by the existing koji powder has low fermentation power and saccharification power, and the wine yield is also low, which is difficult to meet the needs of wine making. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a preparation process of Daqu powder aiming at the deficiencies of the above-mentioned prior art. [0005] The technical scheme adopted in the ...
