Abstract

The invention relates to the field of brewing, and in particular to a brewing pre-processing process of distilled liquor. The brewing raw material consists of the following components in parts by weight: 40 to 50 parts of sorghum, 15 to 25 parts of corn and 30 to 40 parts of paddy. The pre-processing process of the brewing raw material comprises the following steps of adding water which is equivalent to 1 to 3 times that of the volume of the raw material, soaking for at least two hours, and performing steam explosion pre-processing to obtain a steam explosion pre-processed material, wherein the pressure of steam explosion pre-processing is not less than 1.0MPa, and the time of steam explosion pre-processing is not less than 2 minutes. By adopting the raw material, the brewed distilled liquor tastes mellow and is pleasant in smell; after the pre-processing process is adopted, the transformation rate is improved by 20 percent, and the dreg can be used in cellulose extraction or fermentation.

Description

technical field [0001] The invention relates to the field of brewing, in particular to a brewing pretreatment process of liquor. Background technique [0002] Liquor, also known as shochu, is a traditional Chinese beverage. According to the "Compendium of Materia Medica": "Shochu is not an ancient method. It was created in the Yuan Dynasty. The method uses strong wine and bad food to put it into a steamer (referring to a steamer), steams it to make the gas, and uses a vessel to hold the dew." From this we can get It can be seen that the production of liquor in my country has a long history. my country's liquor is world-famous for its rich and colorful aroma styles, and its special production technology is even more unique in the world's brewing industry. The standard definition of liquor (Chinese spirits) is: distilled wine made from grains and grains as the main raw material, with Daqu, Xiaoqu or bran koji and wine mother as saccharification starter, cooking, saccharifying...
