Physicochemical properties: Xanthan gum is a kind of biosynthetic gum, which is a kind of white or light yellow powder. It is a high molecular polysaccharide polymer made of corn starch as the main raw material, fermented by the microorganism Xanthomonas under specific conditions, and then refined, dried and ground. Odorless. Hygroscopic. Soluble in water. At low concentration, it becomes a viscous solution after stirring. The aqueous solution is high pseudoplastic.

Purpose: biochemical research. Stabilizers and emulsifiers for food, non food and cosmetics.
