Introduction (Xanthan Gum CAS:11138-66-2)
Xanthan gum is an extracellular acid heteropolysaccharide produced by fermentation of Bacillus xanthomonas.Xanthan gum is a polysaccharide polymer compound composed of D-glucose, D-mannose and D-glucuronic acid in a ratio of 2:2:1, with a relative molecular weight of more than 1 million.The secondary structure of xanthan gum is the reverse winding of the side chain around the main chain skeleton, which forms a rod-like double helix structure through hydrogen bond.
