Product function and application
Xanthan Gum, which is mainly made from starch, is a high molecular weight polysaccharide produced through fermentation with Xanthomonas Camperstris under the conditions of special nutrient medium, pH, O2-supply and temperature, then purified,dried and milled into white-like or light-yellow free-flowing powder.
The main compositions of Xanthan Gum are D-glucopyranose glucan, D-mannose and D-glucuronic acid. The molecular structure of Xanthan Gum is as below:
X-ray determining indicates that xanthan gum has a antiparallel double helices conformation,on which its special properties of water solution base. Xanthan gum can be widely used in more than twenty industrial fields,such as food, pharmaceutical,fine chemical,agriculture,oil drilling and exploitation,and so on. Comparin with other kinds of gum,xanthan gum has many advantages.
1,Ourstanding viscosity-enhancing property and solubility in water viscosity of 1% xanthan gum water-solution is 100 times of that of the same concentration of gelatin abilities of thickness/viscosity-enhancing are outstanding.
2,Unique pseudo-plasticity rheological property of xanthan gum makes it high-efficient emulsifier and stabilizer.
3,Excellent stability to large range of temperature and PH change.Under the conditions of -18-120°C temperature and 2-12PH,xanthan gum keep its viscosity. It can be used as freeze/thaw stabilizer.
4,Satisfying compatibility with acid,alkaline,brine,enzyme,surface active agent,antiseptic,oxidant and other thickener.
5,Good synergistic action when compounding with guar gum,locust been gum and other gums in proper ratio.
6, Safety and environment. 1983, FAO/WHO approved xanthan gum as safe food additive and didn't limit its additional ratio. As a nature biosynthesis gum,xanthan gum is much more environmental friendly than chemosynthesis gum.

Physical Property: Xanthan gum can be dissolved in cold water and hot water, high viscosity characteristics.
Chemical properties: With strong antioxidant and anti-enzyme effect. The existences of biological activity of enzymes under the conditions still play a role, though in the sodium hypochlorite, hydrogen peroxide.
Usage: it is widely used in food, oil, ceramics, textiles, printing and dyeing, pharmaceutical, paper, paint, etc. on more than 20 industries have applied
Production process: Xanthan gum is a natural polysaccharide and important biological polymers, by the black rot in Brassica campestris Xanthomonas to carbohydrates as the main raw material, the aerobic fermentation biotechnology generated.
Features: H Alias yellow gum, derived plastic, industrial MSG, is the world's most widely produced microbial polysaccharide, the main raw material is corn starch, alcohol through fermentation. Odorless, safe, have good stability. It can be used to produce frozen products, barbecue food.
