Saccharification method of using extruded white sorghum added with mesophilic enzyme as beer auxiliary material

Abstract

The invention discloses a saccharification method of using extruded white sorghum added with mesophilic enzyme as beer auxiliary material. The method comprises the following steps: smashing the white sorghum, and then sieving with a sieve with 30-40 meshes; adjusting the moisture weight percent of smashed white sorghum to be 29.5-30.5% and uniformly mixing the smashed white sorghum with mesophilic alpha-amylase, wherein the additive amount of the mesophilic alpha-amylase is 8.5-9.5 L / ton; conducting extrusion treatment on the smashed white sorghum, wherein the extrusion treatment is conducted in a single screw extrusion machine; cutting up extruded white sorghum by a cutter, cooling to room temperature, drying under the condition that the temperature is lower than or equal to 50 DEG C to enable the moisture weight percent of the extruded white sorghum to be 13.0-15.0%, smashing, and sieving with the sieve with 30-40 meshes for later use; simultaneously putting the extruded white sorghum and smashed barley malt into a gelatinization container for saccharification treatment. The method reduces the saccharification time of using the white sorghum as the beer brewing auxiliary material, and improves the filterability of wort and yield of wort extract.

Description

technical field [0001] The invention relates to the field of beer brewing, in particular to the technical field of low-temperature extrusion and saccharification treatment of white sorghum used for beer brewing with medium-temperature α-amylase. Background technique [0002] The auxiliary materials are used in beer brewing to improve the extraction rate and the stability of beer, and reduce the brewing cost to a certain extent. Based on the fact that the use of auxiliary materials is more economical than malt, many scholars and companies at home and abroad have carried out research on beer auxiliary materials. [0003] In 2004, Dong Jianqiu found through research that the content of peptides in sorghum auxiliary wort is the highest, and when brewing beer with sorghum auxiliary materials, ideal wort components and indicators (such as α-amino nitrogen, wort yield, etc.) can be obtained. C. I. Owuamad et al. used ungerminated sorghum as an auxiliary material to brew qualified ...
