xanthan gum(CAS:11138-66-2)
Product Name: Xanthan Gum Other Name: Yellow adhesive, xanthan gum, xanthomonas polysaccharide Molecular Formula: C8H14Cl2N2O2 Molecular Weight: 241.11496 Appearance: white or light yellow powder Purity: 98.6% CAS Number: 11138-66-2 EINECS number: 234-394-2 Supplier: ZHENYIBIO Xanthan gum is also called Yellow adhesive, xanthan gum, xanthomonas polysaccharide. It is a kind of monospore polysaccharide generated by fermentation of Pseudomonas flava. Since its special macromolecule construction and colloidal properties, it is with several functions. It can be used as emulsifier, stabilizer, gel thickener, impregnating compound, membrane shaping agent and others. It is widely applied in various fields of national economy. Xanthan gum is praised as the monosodium glutamate of industry it is the microbial polysaccharide with largest production scale and extremely wide application. Uses: Xanthan Gum is a gum obtained by microbial fermentation from the xanthomonas campestris organism. it is very stable to viscosity change over varying temperatures, ph, and salt concentrations. it is also very pseudoplastic which results in a decrease in viscosity with increasing shear. it reacts synergistically with guar gum and tara gum to provide an increase in viscosity and with carob gum to provide an increase in viscosity or gel formation. it is used in salad dressings, sauces, desserts, baked goods, and beverages at 0.05 0.50%.
Xanthan gum 80mesh and 200mesh, cream white powder, E415, CAS no.11138-66-2, food thickener, biosynthetic rubber, mainly made of starch, manufacturing process through fermentation process using the microorganism Xanthomonas Campestrisis. Advantages than other gums: outstanding water solubility and high viscosity; excellent stability in temperature and PH value; Function and uses: Xanthan gum is a high performance thickener as the viscosity of 1% is about 100 times stronger than 1% gelatin solution.
