Xanthan Gum
Molecular formula: (C35H49O29)n
HS Code: 3913900090
UN NO: N/A
CAS No: 11138-66-2
Category: Food thickener
Properties: Xanthan gum is a kind of extensive microbial exopolysaccharide produced by fermentation engineering with carbohydrate as main raw material. 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.
Application
1, Food industry: many foods are added to xanthan gum as a stabilizer, emulsifier, suspension agent, thickening agent and processing aid.
2, Daily chemical industry: Xanthan gum, is a good surface active substance, and has antioxidant, prevent skin aging and other effects, can also be used as toothpaste thickening and shaping agent.
3. Medical aspects: Xanthan gum is a functional component in microencapsulated drug materials that 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.
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.
