Xanthan Gum, which is mainly made from starch, is a high molecular weight Polysaccharide produced by fermentation with Xanthomonas Campestris under the conditions of special nutrient medium, pH, O2-supply and temperature, then puritied, dried and milled into while-like or light-yellow free-flowing powder.
The main compositions of Xanthan gum are D-glucopyranose glucan, D-mannose and D-glucuronic acid. The molecular structure of Xanthan Gum is as below:
X-ray dcetermining indicates that xanthan gum has a antiparallel double helices conformation, on which its special properties of water solution base. Twenty industrial fields, such as food., drilling and exploitation. And so on. Comparing with other kinds of gum, xanthan gum has many advantages.
