XANTHAN GUM (XG-C200) is a high molecular weight polysaccharide gum produced by a pure-culture fermentation of a carbohydrate with strains of Xanthomonas campestris, purified by recovery with ethanol or propan-2-ol, dried and milled. It contains D-glucuronic and D-mannose as the dominant hexose unites, along with D-glucuronic acid and pyruvic acid, and is prepared as the sodium, potassium or calcium salt. Its solutions are neutral.
