Abstract

The invention discloses a decolorizing resin for lactase. The decolorizing resin comprises styrene, divinylbenzene, gelatin, juncus roemerianus, methyl isobutyl carbinol, hydroxyethyl methylacrylate, triallyl cyanurate, N-phenylmaleimide, chitosan, vitamin C magnesium phosphate, benzoyl peroxide, polyvinyl alcohol, tributyl phosphate, salicylic acid, hydroxyethyl methyl cellulose and a pore-foaming agent. The invention also discloses a preparation method of the decolorizing resin. The preparation method comprises the following steps of: mixing gelatin, chitosan, hydroxyethyl methyl cellulose, polyvinyl alcohol and salicylic acid to prepare a liquid phase; mixing styrene, divinylbenzene, methyl isobutyl carbinol, hydroxyethyl methylacrylate, triallyl cyanurate, N-phenylmaleimide, benzoyl peroxide, tributyl phosphate and a pore-foaming agent to prepare an oil phase; mixing the juncus roemerianus fiber with vitamin C magnesium phosphate to prepare a solid phase; and mixing the three phases to prepare the polymer. The decolorizing resin is high in decoloration efficiency, short in time and small in lactase activity loss after decoloration.

Description

technical field [0001] The invention belongs to the technical field of decolorizing resin preparation, and in particular relates to a decolorizing resin for lactase and a preparation method thereof. Background technique [0002] Lactase, also known as β-D-galactoside galacto-hydrolase (β-D-galactosidegalacto-hydrolase), is a biological enzyme preparation that is tasteless, odorless and has no safety issues. It can catalyze β~1, 4. The hydrolysis reaction of galactosidic bonds, which hydrolyzes lactose into glucose and galactose, and can also transfer galactosides to generate galactooligosaccharides. [0003] Lactose is the main carbohydrate in mammalian milk and dairy products, accounting for about 5% of milk and other products. About 30% of the calories in whole milk and 60% of the calories in skim milk are provided by lactose. Since the body cannot directly utilize lactose, lactose must be decomposed into simple sugars by lactase before it can be absorbed and utilized. U...
