SPECIFICATION OF XANTHAN GUM
Description : Xanthan gum is a kind of hydrophilic biological polysaccharide, which is made from corn starch after the processes of fermentation with Xanthomonas Campestais, extraction, drying, and grinding. Benefited by its superior thickening and stabilizing effect, shear resist ance and unique pseudoplasticity rheological property, xanthan gum is widely used in food, pharmaceutical, fine chemical, oil drilling and other fields.
