Process for extracting glucose from starch sugar solution

Abstract

The invention provides a process for extracting glucose from a starch sugar solution, and relates to the field of glucose preparation. The process for extracting glucose from the starch sugar solution comprises the following processes: a micro-dilution process, a crystallization process, a hydrolysis process, a decolorization process and a drying process, and the micro-dilution process comprises the following steps: S1, performing micro-dilution: adding distilled water into the starch sugar solution for dilution; S2, performing stirring: fully stirring the starch sugar solution and distilled water to form a solution a, the crystallization process comprises the following steps: S3: performing crystallization: adding a proper amount of sucrase and a 40% sodium hydrogen sulfite solution into the solution a, fully preforming stirring to form a solution b, and crystallizing the solution b; and S4, performing filtering: filtering the precipitate of the solution b to obtain a precipitate c; the processing technology comprises the following processes of micro-dilution, crystallization, hydrolysis, decolorization and drying, the processing time consumption is short, the product production efficiency is high, raw materials are fully extracted, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical field of glucose production, in particular to a process for extracting glucose from starch syrup. Background technique [0002] Starch sugar uses starch-containing grains, potatoes, etc. as raw materials, and is produced by acid method, acid enzyme method or enzymatic method, including maltose, glucose, fructose syrup, etc., collectively referred to as starch sugar. Starch sugar has a long history in our country. Sugar was mentioned in "Qi Min Yao Shu" in more than 500 AD, and the method of making sugar from rice was described in detail. my country's sugar production and consumption have long been dominated by sucrose and supplemented by starch sugar. In recent years, the state has vigorously supported and promoted starch sugar. In the late period of the "Ninth Five-Year Plan", due to the technological progress of the starch sugar industry, the yield and quality improved, and the material consumption decreased; t...
