The decolorising agent selects activated carbon.
The decolorising agent is made of the raw material of following parts by weight：10-15 parts of water process level polyglutamic acid, 4A molecular sieves
10-15 parts of powder, 5-10 parts of N hydroxymethyl acrylamide, 1-5 parts of PEG-60 rilanit specials, trimethylolpropane tris is activated to shrink
0.5-2 parts of glycerin ether, 0.05-0.5 parts of potassium peroxydisulfate, 0.05-0.5 parts of sodium sulfite；
Its preparation method comprises the following steps：
(1) 45-50 DEG C of water is added dropwise until being completely dissolved into N hydroxymethyl acrylamide under stirring, adds potassium peroxydisulfate
And sodium sulfite, the reaction of reflux state insulated and stirred is heated to, mixed liquor is concentrated under reduced pressure after cross-linking reaction is complete, white to be had
Solid separate out when stop concentration, residue is transferred to sealing and standing 8-12h in 5-10 DEG C of environment, filter, gained white solid in
Dried in 55-60 DEG C of baking oven to constant weight, up to self-crosslinking acrylic resin；
(2) 45-50 DEG C of water is added dropwise until being completely dissolved into water process level polyglutamic acid under stirring, and utilizes dilute sulfuric acid
Solution ph is adjusted to 4-5, made self-crosslinking acrylic resin is added, adds 45-50 DEG C of water until self-crosslinking acrylic tree
Fat is completely dissolved, and is heated to the reaction of reflux state insulated and stirred, is sent into gained mixed liquor after esterification and is spray-dried
In machine, micro mist is made through micronizer in dry gained particle, up to polyglutamic acid/acrylic resin carboxylate；
(3) 4A molecular sieve activations powder, PEG-60 hydrogen are added into above-mentioned made polyglutamic acid/acrylic resin carboxylate
Change castor oil and trihydroxymethylpropanyltri diglycidyl ether, be sufficiently mixed, by gained mixture in 50-55 DEG C of hot pressing temperature, heat
The particle of granularity 0.25-0.35mm is made through pulverizer for hot pressing 2-3min under pressure pressure 0.5-1MPa, obtained solid, up to decolourizing
Agent.
The beneficial effects of the invention are as follows：
(1) present invention uses two stage desalting decolorization to liquid glucose, and liquid glucose is realized first with sequential simulated mobile chromatography
Single stage desalting decoloration, remove most salt and pigment contained in liquid glucose；Recycle decolorising agent and ion exchange resin real
Existing two level desalination bleaching, further remaining salt and pigment effectively in removing liquid glucose, make the removal efficiency of salt and pigment in liquid glucose equal
Reach more than 99%, so as to improve the content of steviol glycoside in products made thereby；
(2) decolorising agent of the present invention has two kinds of selections, and one kind is activated carbon, and another kind is self-control decolorising agent, although activated carbon
Institute's saliferous and pigment in liquid glucose can be effectively removed, but can also adsorb a certain amount of steviol glycoside at the same time, so as to cause stevioside
The loss of glycosides；And contained salt and pigment can effectively be removed in liquid glucose by making decolorising agent by oneself, and relative to activated carbon its to stevia rebaudianum
The adsorbance very little of glucosides, so as to reduce the loss late of liquid glucose steviol glycoside after desalination bleaching is handled.
