1, Daqu properties: raw materials for wine making.
2. Xiaoqu Nature: the starter of liquor. There is no difference in appearance between Daqu and Xiaoqu.
Second, the production process is different.
1. Daqu production technology: Daqu is named Daqu by transplanting conidia of Aspergillus into strongly cooked white rice, and then keeping the temperature, so that hyphae flourish on rice grains.
2. Xiaoqu production process: using rice, sorghum, barley, etc. As raw materials, and several Chinese medicines are added as appropriate.
Extended data:
The microorganisms contained in Xiaoqu are mainly Rhizopus, Mucor and Yeast. It plays the role of saccharification and fermentation in the brewing process. It has the characteristics of small size and less heat production, and is suitable for the climate conditions in southern China. Xiaoqu liquor is called Xiaoqu liquor, such as yellow rice wine and sweet wine.
Under the strong action of amylase and glucoamylase produced by Aspergillus, the starch in rice was enzymatically decomposed into sugar by Daqu. Therefore, Daqu and malt have been used as raw materials of sugar since ancient times to brew wine, sweet wine and red bean paste.
Wheat instead of rice is called wheat koji. Raw materials such as barley, wheat, peas, etc. are crushed, kneaded with water, and pressed into brick-shaped fermented grains of different sizes, so that various microorganisms in nature can grow on them.
