Problems solved by technology

A large amount of glucose is not effectively utilized, resulting in low glucose yield and economic benefits
As a fermentation raw material, since most microorganisms cannot utilize the disaccharides, trisaccharides and other oligosaccharides therein, it also causes waste of raw materials

Abstract

The saccharizing process for glucose production includes the following steps: setting crystallized glucose mother liquid or the mixture of crystallized glucose mother liquid and starch emulsion into saccharifying tank; and saccharifying via adding enzyme of 0.4-0.5 L/T at pH 4.2-4.5 and 60-62 deg.c for 40-60 hr. The process has raised crystallized glucose mother liquid utilizing rate, disaccharide, trisaccharide and other oligosaccharides converted into glucose, DE value up to 91-96 %, raised glucose yield and low production cost.

Description

Technical field: [0001] The invention relates to a method for effectively utilizing crystallized glucose mother liquor, specifically saccharifying the mother liquor produced in the crystallized glucose production process to convert disaccharides, trisaccharides and polysaccharides in the mother liquor into glucose. Background technique: [0002] Glucose is the most common monosaccharide substance and an important basic chemical medicine, and one of the main energy substances of the human body and animals. Widely used in food, medicine, chemical and other industries. During the glucose production process, a large amount of glucose mother liquor will be produced. The mother liquor generally contains about 50% dry matter and about 89% DE value (about 78% for glucose, about 13% for disaccharides, about 4% for trisaccharides and above sugars). Therefore, in addition to containing a large amount of glucose, the mother liquor also contains a large amount of oligosaccharide compone...
