Embodiment Construction

[0051] The present invention will be further described below in conjunction with the examples, but not as a limitation of the present invention.

[0052] Utilize waste molasses or waste glucose mother liquor as the method for basic raw material production xanthan gum, this method comprises following processing steps:

[0053] A, the slant bacterial classification is made into seed liquid through expanding culture;

[0054] B, the seed liquid prepared in the A step is pressed seed liquid: fermented medium is that the inoculation amount of 15% inserts fermented medium and ferments, and wherein fermented medium comprises the component of following mass parts:

[0055] Waste molasses or glucose mother liquor 3.5%-4.2% Enzymatic hydrolyzed cottonseed protein 0.18%

[0056]Soy protein peptide 0.2-0.3% Soy flour 0.2%

[0057] CaCO 3 0.2% FeSO 4 12ppm

[0058] Polyether defoamer 0.08%

[0059] The technological conditions in the fermentation process are:

[0060] Within 10 ho...

Abstract

The invention belongs to tiny organism fermentation and abstraction, particularly relates to a method for preparing xanthan gum prepared with exhausted molasses or deposed gluecose mother liquor. The preparing process comprises expanding and culturing oblique culture to prepare seed liquor, transferring the seed liquor into fermentation medium with deposed gluecose mother liquor as main carbon source, ventilation fermenting by assisting necessary nitrogen source and nutritive matter, pretreating, extracting, cleaning, drying and crushing to obtain xanthan gum. The invention solves a series problems existing in present technology such as wasting food supplies resource, high cost and not conforming national industry policy. Also the invention satisfies the re-using of exhausted molasses or deposed gluecose mother liquor and solves the problem of serious pollution caused by abandoning the same, meanwhile, the prepared xanthan gum has same property, simple art, low cost and the technologyadvancing direction is suitable for national industry policy comparing with the product prepared in traditional method.

Description

technical field [0001] The invention belongs to microbial fermentation and extraction, in particular to a method for producing xanthan gum using waste molasses or waste glucose mother liquor as basic raw materials. Background technique [0002] At present, the preparation of xanthan gum is to inoculate the production strains in the sterile medium with starch as the main carbon source for fermentation. The fermentation process is to carry out aerobic fermentation under the specified temperature and pH conditions. Xanthomonas campestris extracts the end product of fermentation to obtain xanthan gum. The above-mentioned prior art has shortcomings such as wasting a large amount of grain resources, high manufacturing cost, and not conforming to national industrial policies. Contents of the invention [0003] The purpose of the present invention is to provide a method for producing xanthan gum using industrial waste—waste molasses or waste glucose mother liquor as the basic raw...
