Xanthan Gum Food Grade

is a Polysaccharide secreted by the bacterium Xanthomonas campestris , used as a Food Additive and rheology modifier, commonly used as a food thickening agent (in salad dressings, for example) and a stabilizer (in cosmetic products, for example, to prevent ingredients from separating). It is composed of pentasaccharide repeat units, comprising glucose, mannose, and glucuronic acid in the molar ratio 2.0:2.0:1.0. It is produced by the fermentation of glucose , sucrose , or lactose . After a fermentation period, the polysaccharide is precipitated from a growth medium with isopropyl alcohol , dried, and ground into a fine powder. Later, it is added to a liquid medium to form the gum.
