Application： 1. Food: Xanthan gum is added to many foods as stabilizer, emulsifier, suspending agent, thickener and processing assistant. Xanthan gum can control the rheology, structure, flavor and appearance of products, and its pseudoplasticity can ensure good taste, so it is widely used in salad dressings, bread, dairy products, frozen foods, beverages, condiments, brewing, candy, cakes, soup and canned foods. In recent years, people in more developed countries tend to worry that the calorific value in food is too high to make them fat. Xanthan gum can not be directly degraded by human body, which dispels this concern.   2. In terms of daily chemical industry: Xanthan gum contains a large number of hydrophilic groups, which is a good surfactant and has the effects of anti-oxidation and anti-aging. Therefore, xanthan gum is used as its main functional component in almost most high-end cosmetics.   3. In medicine: Xanthan gum is a functional component of the currently hot microcapsule drug capsule material in the world, and plays an important role in controlling drug release; Due to its strong hydrophilicity and water retention, it has many applications in specific medical operations, such as forming a dense water film to avoid skin infection; Alleviate thirst after radiotherapy.  4. Industrial and agricultural applications: in the petroleum industry, due to its strong pseudoplasticity, the low concentration of xanthan gum (0.5%) aqueous solution can maintain the viscosity of drilling fluid and control its rheological properties, so the viscosity at the high-speed rotating bit is very small, saving power;
