Xanthan gum, also known as Hansen gum, is a kind of extracellular polysaccharide, which is produced by Xanthomnas campestris with carbohydrate as the main raw material (such as corn starch) by fermentation engineering. It with unique rheological property, good water solubility, on the thermal stability and acid and alkali, and a variety of salts has good compatibility, as thickener, suspending agent, emulsifier, stabilizer, can be widely used in food, oil, and so on more than 20 industries, is currently the world's largest production and has a wide range of USES of microbial polysaccharides.
