Abstract

The invention belongs to the technical field of production of xanthan gum, in particular to a xanthomonas campestris and a method for preparing the xanthan gum specially used for soy sauce thereby. The xanthomonas campestris is collected in the general microorganism center of China committee for culture collection of microorganisms, the collection date is February 1st 2010, the collection number is CGMCC No. 3623, and the classification name is Xanthomonassp. The preparation method of the xanthan gum comprises fermentation step, disinfection step, primary extraction, primary separation, secondary extraction and secondary separation. The xanthomonas campestris has high sugar conversion rate and strong gum-producing capability in practical production, the produced xanthan gum has fast hydration speed and does not easily form the granule shape, the prepared xanthan gum improves the coloring capability and fast dissolving speed, has no precipitate formation and greatly improves the appearance of sauce.

Description

technical field [0001] The invention belongs to the technical field of xanthan gum production, and in particular relates to a xanthan bacteria and a method for preparing xanthan gum special for soy sauce. Background technique [0002] Xanthan gum is the best thickening stabilizer for soy sauce, which can enhance the coloring ability of soy sauce, prevent the soy sauce from sedimentation, and make the soy sauce have the effect of thick hanging bottle. [0003] At present, the production process of xanthan gum used in soy sauce on the market is: using Xanthomonas campestris, using corn and soybeans as raw materials for aseptic fermentation, then mixing the fermented liquid with alcohol, washing, and fully mixing and dehydrating. The fermentation liquid is poured into the centrifuge for centrifugation; then the obtained material is fully mixed with alcohol again, the mixed material liquid is injected into the centrifuge, and the separated material is sent to the molding machine...
