Xanthan gum (Xanthan gum), also known as xanthan gum, is a microbial exopolysaccharide with a wide range of functions produced by fermentation engineering of Xanthomonas campestris with carbohydrates as the main raw material (such as corn starch). It has unique rheology, good water solubility, stability to heat and acid and alkali, and good compatibility with various salts. It can be widely used as a thickener, suspending agent, emulsifier, and stabilizer. Used in more than 20 industries such as food, petroleum, and medicine, it is the microbial polysaccharide with the largest production scale and extremely wide uses in the world.

1. Food: Xanthan gum is added to many foods as stabilizer, emulsifier, suspending agent, thickener and processing aid.
2. Daily chemical industry: Xanthan gum contains a large number of hydrophilic groups, which is a good surface active substance, and has the effects of anti-oxidation and preventing skin aging.
3. Medical aspects: Due to its strong hydrophilicity and water retention, there are many specific medical applications, such as forming a dense water film to avoid skin infections; reducing thirst after radiation therapy, etc.
4. Application in industry and agriculture: Due to its excellent salt resistance and heat resistance, it is widely used in drilling in special environments such as oceans and high-salt areas, and can be used as an oil recovery agent to reduce dead oil areas , to increase oil recovery.
