Solid-state white spirit fermentation and brewing method by using white spirit raw materials extruded with enzyme or without enzyme

Abstract

The invention relates to a solid-state white spirit fermentation and brewing method by using white spirit raw materials extruded with an enzyme or without the enzyme, which belongs to the technical field of brewing of white spirit. The invention firstly provides a processing method for extruding the white spirit raw materials with the enzyme or without the enzyme and further provides the solid-state white spirit fermentation and brewing method by using the white spirit raw materials extruded with the enzyme or without the enzyme. The method is mainly technically characterized by providing reasonable parameters for an extrusion system of the white spirit raw materials and providing the reasonable parameters for the solid-state process white spirit production by using the extruded white spirit raw materials. Compared with the prior art, during the fermentation process of fermented grains of the white spirit raw materials which are extruded with the enzyme or without the enzyme, the degradation of starch is thorough, the fermentation time is shorter and the flavor is thicker. Compared with the traditional solid-state white spirit fermentation and brewing process which is universally adopted at present, the solid-state white spirit fermentation and brewing method by using the white spirit raw materials extruded with the enzyme or without the enzyme of the invention can eliminate the process steps of heating, steam boiling, save energy consumption, reduce the cost, increase the utilization rate of the raw materials, increase the yield of the white spirit, shorten the fermentation period and realize the unique flavor.

Description

technical field [0001] The invention belongs to the technical field of a processing method for extruding and adding enzyme-free liquor raw materials and a solid-state fermented liquor brewing method in a liquor brewing process. Background technique [0002] At present, all kinds of famous and high-quality liquor in China are mostly produced by solid fermentation method, which still has the characteristics of high grain consumption, high energy consumption, long production cycle and low production efficiency, which restrict its development. [0003] Extrusion technology has been widely used in the food industry. In addition to being applied to snack food, breakfast food (Ana Laura, 2008; R A King, 2008), candy and chocolate food (Zhang Yuzhong, 1998; D J van Zuilichem, 1985; Mark Jury, 2000), textured protein food (Fengliang Chen, 2010 ; Crowe T W, 2001), fermentation raw material pretreatment (Shen Dechao, 2002; Ken`ichi Ohtsubo, 2005), etc. [0004] The extruded grain raw...
