xanthan gum NEW

Chinese name: Xanthan gum

English name: Xanthan gum

CAS: 11138-66-1

EINECS number: 234-394-2

Molecular formula: C35H49O29

MDL number: MFCD00131256

Molecular weight: 241.115

Appearance: Light brown powder

Appearance: Milky white to light yellow brown powder. Soluble in water at room temperature into translucent viscous liquid, insoluble in ethanol, isopropyl alcohol and acetone and other organic solvents. Xanthan glue solution has good viscosity and is quite stable in the range of -4 ~ 80℃, when the concentration of ethanol, isopropyl alcohol or acetone in water exceeds 50% ~ 60%, it will cause the precipitation of xanthan gum. The ability to resist acid and alkali and bioenzyme degradation is very strong, and the viscosity of xanthan glue solution is not affected by Ph value in the range of 1.5 ~ 13. Xanthan gum is a natural polymer compound with oral LD50 > 10g/kg and ADI in rats without special requirements (FAO/WHO, 1994).

Solubility: Xanthan gum (11138-66-2) is a polysaccharide polymerization of high molecular weight anionic starch produced by Xanthomonas campestris after fermentation, soluble in cold water and hot water, insoluble in common organic solvents.
