Abstract

The invention provides a novel method for decolorizing a peach gum solution by a cold plasma-photocatalysis technology. The method uses dielectric barrier discharge to produce cold plasma (low temperature plasma) and excites a photocatalyst at the same time to decolorize the peach gum solution. Original peach gum is used as a raw material and sequentially subjected to swelling, impurity removal and hybridization. The concentration of the hydrolysate of the original peach gum is 0.01 to 0.10 kg / L, and is decolorized by a cold plasma-photocatalysis reactor with external voltage of between 16 and 28 kv. The inside of the reactor is provided with a Raschig ring carrying the photocatalyst. Compared with the prior method for decolorizing peach gum, the method avoids chemical agent residue in peach gum products and is simple in process, short in decolonization time and good in effect. In addition, peach gum obtained after freeze drying can be widely used in medicine, food, chemical, printingand other industries.

Description

technical field

[0001] The invention relates to the technical field of peach gum processing, in particular to a method for decolorizing a hydrolyzed solution. Background technique

[0002] my country's peach gum resources are very rich and widely distributed, mainly concentrated in North China, Central China, Northwest China and other places. Since peach gum is a by-product, it is not widely used. At present, manufacturers mainly add sodium hypochlorite, H 2 o 2 As a decolorizing agent, but these will cause the residue of chemical reagents, so the application in food additives is limited. While using activated carbon to decolorize, some sugars will also be adsorbed. There are two invention patents on peach gum that have been publicly published, one of which is: a method for making solid peach gum and its products (application number: 94114268.X, publication number: CN 1107495A), mainly related to solid peach gum Its decolorization process mainly relies on chemicals such...
