Special decolorization resin for starch saccharification liquid

Abstract

The invention discloses a special decolorization resin for starch saccharification liquid and relates to the technical field of processing of resin. The resin is prepared from the following raw materials in parts by weight: 70-80 parts of styrene, 40-50 parts of hydroxyethyl methylacrylate, 20-30 parts of divinyl benzene, 15-20 parts of pore-foaming agents, 6-11 parts of chlorinated polyethylene, 4-8 parts of linear low-density polyethylene, 4-8 parts of water-soluble chitosan, 3-6 parts of N,N-dimethylamino ethyl ester, 3-6 parts of sesbania gum, 3-6 parts of anionic polyacrylamide, 2-4 parts of N-phenylmaleimide, 2-4 parts of sodium tripolyphosphate, 1-2 parts of sodium polystyrenesulfonate, 1-2 parts of agar powder, 0.5-1 part of methyl hydroxybenzoate, 0.5-1 part of vitamin C magnesium phosphate, 20-30 parts of ethyl alcohol and 250-300 parts of water. The prepared resin is capable of effectively removing colored impurities in the starch saccharification liquid; the decolorization rate reaches over 98%; moreover, the decolorization time is short; the processing cycle of starch saccharification can be shortened.

Description

[0001] Technical field:

[0002] The invention relates to the technical field of resin processing, in particular to a special decolorizing resin for starch saccharification liquid.

[0003] Background technique:

[0004] During the saccharification reaction of starch sugar, the color will generally appear to deepen, and it is necessary to add activated carbon to remove the color during refining. The reason for the darkening of the color is mainly related to the carbonyl ammonia reaction that occurs during saccharification. The carbonyl group in the reducing sugar reacts with the free amino acid or the free amino acid of the amino acid residue in the protein molecule. This reaction is called "Maillard reaction". However, decolorization with activated carbon cannot achieve the desired decolorization effect once, and two or more decolorizations with activated carbon are required, which increases the decolorization cycle and cost input. In response to this situation, our company h...
