Abstract

The invention discloses a refining method of starch sugar liquor. The refining method of the starch sugar liquor comprises the following steps of: firstly inducing the starch sugar liquor from one end of a separation column with a cation exchange resin as a fixed phase into the separation column so that metal cations contained in the starch sugar liquor and the cation exchange resin generate ion exchange to obtain a solution A; inducing the solution A from one end of the separation column with an anion exchange resin as the fixed phase into the separation column so that a silicon compound contained in the solution A and the anion exchange resin generate the ion exchange to obtain refined starch sugar liquor from the other end of the separation column with the anion exchange resin, wherein the cation exchange resin is Na type cation exchange resin, and the anion exchange resin is OH type anion exchange resin. According to the refining method of the starch sugar liquor, the silicon compound contained in the starch sugar liquor can be effectively removed.

Description

technical field [0001] The invention relates to a method for refining starch syrup. Background technique [0002] Starch sugar is a general term for the production of sugar products using starch as raw material. [0003] Starch sugar products: mainly maltodextrin, glucose syrup, aqueous glucose and crystalline glucose, maltose, fructose syrup, crystalline fructose and various oligosaccharides. [0004] In the prior art, the production of starch sugar is carried out according to the following technological process: [0005] [0006] In this production process, due to the presence of soluble silicon compounds in the raw and auxiliary materials, if these silicon compounds are not removed before ion exchange, they will be brought into the concentrate, resulting in a decrease in product quality. [0007] Therefore, there is an urgent need to find a method for effectively removing silicon compounds in starch sugar liquid. Contents of the invention [0008] The object of th...
