A polysaccharide material produced by the fermentation of sugar by the bacterium Xathomonas campestris, originally isolated from the rutabaga plant. Xanthan is primarily composed of Mannose, Glucose, and glucuronic acid units. It is a cream-colored powder that is dissolves in water to produce a thick viscous solution at very low concentrations. Xanthan remains stable over a wide temperature range and forms a strong film on drying. Xanthan is used as a binder, an extender and stabilizer in foods and cosmetics.
