Problems solved by technology

CN101363037A discloses a xanthan gum medium prepared from starch waste water and active medical stone granules. Although the medium can reduce the cost of the medium to a certain extent, its preparation steps are very cumbersome, and the popularization and application of xanthan gum is not utilized.
The expansion of production has caused fierce competition in the product market, prices have been falling, and the profits of production companies are getting lower and lower, even reaching the edge of costs. Expansion in higher-end market segments

Abstract

The invention provides a production method of low-cost and high-quality xanthan gum. The method comprises the following steps of using a fermentation culture medium using dry process corn powder as major raw materials; using Xanthomonas arboricola for fermentation to prepare fermentation liquid; obtaining xanthan gum by using a fermentation liquid post treatment step, wherein through being metered by 100 percent of the total volume of the fermentation culture medium, the fermentation culture medium comprises 4 to 7 percent of the dry process corn powder according to the mass volume ratio; the mass volume ratio has the unit of Kg / L. In addition, the fermentation culture medium for producing xanthan gum through Xanthomonas arboricola fermentation provided by the invention comprises the major raw materials of dry process corn powder. Through the replacement of the fermentation raw materials; the production cost of the xanthan gum is reduced.

Description

technical field [0001] The invention relates to the technical field of xanthan gum production, in particular to a production method of low-cost and high-quality xanthan gum. Background technique [0002] Xanthan gum is an extracellular acidic heteropolysaccharide produced by the fermentation of Xanthomonas bacteria. It is a polysaccharide polymer compound composed of D-glucose, D-mannose and D-glucuronic acid, with a relative molecular mass of 100. More than ten thousand. The secondary structure of xanthan gum is that the side chains are reversely wound around the backbone of the main chain, and are maintained by hydrogen bonds to form a rod-shaped double helix structure. The unique structure forms the strong chemical stability of xanthan gum. [0003] Xanthan gum is currently the most superior bio-glue. It has the general properties of long-chain polymers, and it contains more functional groups than ordinary polymers, and it will show unique properties under certain condi...
