Pure-grain solid-state liquor brewing process

Abstract

The invention discloses a process which adopts non glutinous sorghum and waxy wheat as materials to brew pure-grain solid-state liquid and solves the technical problems that the high-quality liquor cannot be obtained by adopting the non glutinous sorghum as the materials through the pure-grain solid-state brewing process in the prior art. In the method, the mixture of the non glutinous sorghum and the waxy wheat is used as the grain materials, the raw material ratio of the grain materials is controlled and the dosage of loosening agent is adjusted in a fermentation process, so that the defects of spicy taste and heavy odor of the liquor brewed by the non glutinous sorghum are solved. The brewing process is further optimized from condition controls based on the method, wherein the condition controls mainly comprise material preparing condition control, grain brewing condition control, saccharifying condition control and fermenting condition control, so that the scientific metering problems of the key process conditions such as the grain brewing time, the saccharifying time, the fermenting time and the like are in particular solved. The method provided by the invention can save the consumption of the glutinous sorghum in the pure-grain solid-state liquor brewing, and ensures the quality of the produced liquor while greatly reducing the material cost of the liquor brewing. Moreover, the method has no special requirements on conventional liquor brewing devices including the fermentation pits.

Description

technical field [0001] The invention relates to a liquor brewing process, in particular to a pure grain solid-state fermentation liquor brewing process, which belongs to the field of alcoholic beverages and food processing. Background technique [0002] The pure grain solid liquor brewing method is a unique traditional craft in the Chinese liquor industry with a history of thousands of years. In the liquor industry, pure grain liquor refers to sorghum, corn, wheat, rice, glutinous rice, barley, buckwheat and beans as raw materials (excluding potatoes), which are made in mud pits, stone pits or pottery, porcelain, cement, etc. Liquor products obtained through natural fermentation in a container in a solid or semi-solid state (applicable to rice-flavored liquor) and high-temperature distillation. This kind of liquor is also called traditional craft liquor. Because liquor is made from grains, natural fermentation and high-temperature distillation, it has unique aromas, such as...

AI Technical Summary

Problems solved by technology

The main difference between japonica sorghum and waxy sorghum is the high amylose content. The characteristics of japonica sorghum winemaking process parameters are large water absorption, slow water absorption rate, high gelatinization temperature, and high water absorption expansion rate, which is prone to low wine production during the brewing process. , high acidity, high water content, and poor quality of wine quality, so it is difficult to put into large-scale production the pure grain liquor brewing technology using only japonica sorghum; The raw materials used, such as Moutai and Luzhou Laojiao, use glutinous sorghum as a single raw material for winemaking

The pure grain solid liquor market has a large demand for glutinous sorghum, but high-quality glutinous sorghum is only produced in small areas such as Sichuan and Guizhou. With the development of pure grain solid liquor industry, the production of glutinous sorghum can no longer meet the needs of the wine industry. The rising price further pushes up the price of pure grain solid liquor
