Abstract

The invention relates to a process method for producing yeast polysaccharide and yeast nucleotide from yeast, which solves the problems of low yield, long period, high equipment investment and high production cost existing in the conventional process for extracting the yeast polysaccharide and the yeast nucleotide. The yeast polysaccharide and the yeast nucleotide are respectively extracted by taking waste beer yeast as a raw material through the steps of high-pressure homogenization and performing of an enzyme method. The process method has the characteristics of high yield and purity of extracted yeast polysaccharide, high yeast nucleotide content, short extraction time, low enzyme consumption, low equipment investment and production cost and suitability for large-scale industrial production.

Description

technical field

[0001] The invention relates to a yeast treatment process, in particular to a process method for yeast to produce zymosan and nucleotides. Background technique

[0002] The waste yeast in the production of beer industry in our country is mostly treated cheaply as roughage raw material, resulting in a lot of waste of resources. If the waste yeast is fully developed and utilized so that the effective components in it can be recovered reasonably, the economic benefits will be considerable. At present, the treatment of waste yeast mainly uses waste yeast as raw material to extract zymosan by acid-base method or enzyme-alkaline method. Polysaccharides, but the required enzyme concentration is high, and the time for enzymolysis and alkali treatment is long (enzymolysis time is at least 12h, and alkali treatment time is at least 4h), which greatly increases production costs and affects production efficiency and production scale. Masson et al. published a "Study on...
