Producing method of instant xanthan gum

Abstract

The invention belongs to the technical field of microorganisms and discloses a producing method of instant xanthan gum. The producing method comprises the steps of preparing a fermentation liquid, preparing xanthan gum particles and a xanthan gum solution, and adding a surfactant. The yield of the xanthan gum prepared by the method is high, the xanthan gum is dissolved fast, is free from fisheyes, can be used for industrial production and has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a production method of instant xanthan gum. Background technique [0002] Xanthan gum, also known as xanthan gum, is a widely used microbial polysaccharide produced by Xanthomonas bacteria using carbohydrates as raw materials through fermentation. Xanthan gum is soluble in cold water and hot water, and forms a high viscosity after being fully hydrated. Solution, with efficient thickening effect, good temperature resistance, salt resistance, heat resistance and acid and alkali resistance. Xanthan gum has good water solubility and forms a high-viscosity solution after being fully hydrated. It is currently the bio-glue with the best performance in the world that integrates thickening, suspension, emulsification, and stabilization; it can be used as an emulsifier, stabilizer, and gel enhancer. Thickener, wetting agent, film forming agent, etc.; widely used in food...

Problems solved by technology

However, fish eyes are easily formed during the dissolution process, that is, the surface of the glue particles in the water is swelled by water to form a colloidal layer. At this time, the molecular chains have not formed random coils that can move freely; The process of internal penetration, and the cementation between the particles to form a block, forming a large block with an initial gel on the surface and a dry core inside, reducing its use efficiency

In order to solve the dissolution rate of xanthan gum particles, many manufacturers adopt various methods to solve the production of so-called "instant xanthan gum", such as using stirring to disperse, adding surfactants, prolonging soaking time, etc. These methods are only Facilitates the dispersion of xanthan gum in aqueous solution without achieving true instant dissolution

[0004] On the other hand, the yield of xanthan gum depends on the gel production rate of xanthan gum strains. The existing xanthan gum strains have a low yield, and the existing xanthan gum-based biopolysaccharide products also generally exist in aqueous solutions. Viscosity is unstable, and product quality declines under high temperature conditions. Therefore, it is very important to breed and utilize xanthan gum-producing microbial strains in the prior art to develop high-efficiency rubber-producing mixed bacterial agents.
