Xanthan Gum

Xanthan gum is a kind of monospore polysaccharide generated by fermentation of Pseudomonas flava, with appearance of white or light yellow powder. Since its special macromolecule construction and colloidal properties, it can be used as emulsifier, stabilizer, gel thickener, impregnating compound, membrane shaping agent and others. It is the microbial polysaccharide with largest production scale and extremely wide application.
