Xanthan gum is a light yellow to white flowable powder with a slight smell. Easily soluble in cold and hot water, the solution is neutral, resistant to freezing and thawing, and insoluble in ethanol. Disperse and emulsify in water to become a stable hydrophilic viscous colloid.
Xanthan gum
is an extracellular acidic heteropolysaccharide produced by fermentation of Xanthomonas spp. It is a polysaccharide polymer compound composed of D-glucose, D-mannose and D-glucuronic acid in a ratio of 2:2:1. It has unique rheology, good water solubility, stability to heat and acid and alkali, good compatibility with various salts, and is used as thickener, suspending agent, emulsifier and stabilizer. It has a wide range of applications in more than a dozen fields such as food, petroleum, medicine, and daily chemicals.
