Xanthan gum 99.5% Milky white to yellowish brown powder

Xanthan gum, also known as Hanseum gum, is an extracellular acidic heteropoly sugar produced by Xanthomnas campestris, a kind of Xanthomnas campestris, which uses carbohydrates as main raw materials (such as corn starch) through fermentation engineering. Microbial exopolysaccharides with a wide range of effects. It is a polysaccharide polymer compound composed of D-glucose, D-mannose and D-glucuronic acid according to 2:2:1, with a relative molecular weight of more than 1 million. The secondary structure of xanthan gum is that the side chain is reversed wound around the main chain skeleton, and the rod-like double helix structure is maintained through hydrogen bonds. It has unique rheological properties, good water solubility, stability of heat and acid base, and good compatibility with a variety of salts. As a thickening agent, suspension agent, emulsifier, stabilizer, can be widely used in food, petroleum, medicine and other more than 20 industries, is currently the world's largest production scale and very widely used microbial polysaccharide.

Xanthan gum is light yellow to white movable powder, slightly smelly. Soluble in cold and hot water, neutral solution, resistant to freezing and thawing, insoluble in ethanol. Water disperses and emulsifies into a stable hydrophilic viscous colloid.
Because of its unique properties, xanthan gum has been widely used in more than a dozen fields, such as food, petroleum, medicine, daily chemical industry, etc. Its high degree of commercialization and wide range of application make any other microbial polysaccharide unmatched.

product use:

1, food: many foods are added to Xanthan gum as a stabilizer, emulsifier, suspension agent, thickening agent and processing aid. Xanthan gum can control the rheology, structure, flavor and appearance of the product, and its false plasticity can ensure good taste, so it is widely used in salad dressing, bread, dairy products, frozen food, drinks, condiments, brewing, candy, pastry, soup and canned food. In recent years, people in more developed countries often worry that the calorific value of food is too high and will make them fat. Xanthan gum can not be directly degraded by the human body to dispel people's concerns. In addition, it was reported in Japan in 1985 that xanthan gum was the most effective anticancer agent among eleven food additives tested in comparison.
2, daily chemical industry: Xanthan gum molecules contain a large number of hydrophilic groups, is a good surface active substance, and has antioxidant, prevent skin aging and other effects, therefore, almost the vast majority of high-grade cosmetics are xanthan gum as its main functional components. In addition, xanthan gum can also be used as a substance of toothpaste thickening and shaping, reducing the surface wear of teeth.
3. Medical aspects: Xanthan gum is a functional component in microcapsule drug materials, which is currently hot in the world, and plays an important role in controlling the slow release of drugs. Due to its strong hydrophilicity and water retention, there are many specific medical applications, such as the formation of a dense water film, thus avoiding skin infection; Relieve thirst after radiotherapy. In addition, Li Xin and Xu Lei have written that xanthan gum itself can significantly enhance the humoral immune function of mice.
4, industrial and agricultural applications: in the petroleum industry, due to its strong pseudoplasticity, low concentration of xanthan gum (0.5%) aqueous solution can maintain the viscosity of drilling fluid and control its rheological properties, so in the high-speed rotation of the bit site viscosity is very small, save power; High viscosity is maintained in the relatively static borehole area to prevent wall collapse. And because of its excellent salt resistance and heat resistance, it is widely used in Marine, high salt zone and other special environment drilling, and can be used as oil recovery agent, reduce dead oil areas, improve oil recovery rate.
