Problems solved by technology

[0004] As the production of enzyme preparations becomes more and more stable and mature, glucoamylases have been widely used in the brewing industry to replace the traditional koji and solve some of the disadvantages of traditional koji. It is far superior to the original saccharification koji, but there are also some shortcomings, such as the saccharification enzyme is relatively single, the enzyme activity is weak, the saccharification power becomes weak after its existence, and the fermentation period is long, etc.

Abstract

The invention discloses a saccharifying agent for brewing. The agent comprises, by weight, 90-98 parts of saccharifying enzyme, 1-6 parts of amylase or / and 1-6 parts of protease. The invention further discloses a preparation method of the saccharifying agent. The saccharifying agent has the advantages that the defects of long fermentation period and weak enzyme activity can be overcome, and the industrial application prospect is bright.

Description

technical field [0001] The invention relates to a saccharifying agent for brewing wine and belongs to the field of fermentation. Background technique [0002] During the brewing process, potatoes, grains, and wild plant raw materials are pressure-cooked and gelatinized to become dissolved starch, but they cannot be directly used by yeast to ferment and produce alcohol. Therefore, a certain amount of saccharification agent must be added to the gelatinized mash after cooking to make the dissolved starch into sugars that can be used by yeast. This process is to convert starch into sugar, called saccharification . The catalysts used to convert starch into fermentable sugars are called saccharification agents. [0003] The saccharification agent used in traditional brewing is the saccharification koji made by the brewery. Due to the complex enzyme system and poor aseptic conditions in the manufacturing process, the saccharification koji made by the brewery makes the fermentatio...
