Abstract

The invention provides a method for separating and extracting L-arabinose from wasted wood sugar mother liquid from wood sugar production. The method comprises the following steps: the wood sugar mother liquid is decolorized; the decolorized wood sugar mother liquid is desalted by using ion exchange resin; the desalted defecated wood sugar mother liquid is diluted and added by required nitrogen source and inorganic salt for germicidal treatment; microzyme is inoculated into the sterilized wood sugar mother liquid for fermenting cultivation; the microzyme is removed after the ferment is finished, supernatant is processed with the methods of discolorationt, desaltification, concentration, and the like, to get colorless defecated fermenting liquid; the fermenting liquid is further concentrated, crystallized and dried to get the L-arabinose of high purity. The method has the advantages of no pollution, low energy consumption and low cost, and is suitable for industrial large-scale production.

Description

technical field

[0001] The invention relates to a method for producing L-arabinose, in particular to a method for separating and extracting L-arabinose from waste xylose mother liquor for xylose production. Background technique

[0002] my country is a big producer of xylose and xylitol, xylitol needs to be used as a raw material for the production of xylitol, and the current production capacity of xylitol in my country is about 60,000 tons. About one ton of xylose is needed to produce one ton of xylitol, and about one ton of xylose mother liquor is left for every ton of xylose produced, and about 60,000 tons of xylose mother liquor are produced every year. Some of these xylose mother liquors are used as pigment raw materials for the production of soy sauce in the sauce factory, and some are used for hydrogenation to make liquid xylitol, but many parts become industrial wastes that are difficult to handle. The content of L-arabinose in this xylose mother liquor is even as h...
