Description：

Xanthan gum, also known as Hansheng gum, is a widely used microbial extracellular polysaccharide produced by Xanthomonas campestris through fermentation engineering with carbohydrate as the main raw material (such as corn starch). It has unique rheology, good water solubility, stability to heat, acid and alkali, and good compatibility with a variety of salts. As a thickener, suspending agent, emulsifier, stabilizer, it can be widely used in more than 20 industries, such as food, petroleum, medicine, and so on. It is currently the largest production scale and widely used microbial polysaccharide in the world.

Application：

Xanthan gum is widely used in more than ten fields such as food, petroleum, medicine and daily chemical industry due to its unique properties. Its high degree of commercialization and wide range of application are beyond the reach of any other microbial polysaccharide.

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. In addition, according to a report from Japan in 1985, eleven food additives were compared and tested. Xanthan gum was the most effective anticancer agent among them.

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. In addition, xanthan gum can also be used as a component of toothpaste to substantially thicken and shape, and reduce tooth surface wear.

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. In addition, Li Xin and Xu Lei once wrote that xanthan gum itself has a significant enhancement effect on the humoral immune function of mice.

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; However, high viscosity is maintained at the relatively static drilling position, so as to prevent borehole wall collapse. And because of its excellent salt resistance and heat resistance, it is widely used in drilling in special environments such as marine and high-salinity areas, and can be used as oil displacement agent for oil production, reducing dead oil areas and improving oil recovery.
