Xanthan Gum 11138-66-2

More Details

　　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 anti parallel 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. Compare with other kinds of gum, Xanthan gum has many advantages.

　　1, Our standing viscosity-enhancing property and solubility in water. The viscosity of 1% Xanthan gum water-solution is 100 times of that of the same concentration of glutin. The 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 -18-120ºC temperature and 2-12PH,xanthan gum keep its viscosity and other properits steady. 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 protection. In 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.

　　Food Grade FCCIV

　　Food Grade Xanthan Gum can be widely used as salt/acid resistant thickener, high efficient suspension agent and emulsifier, high viscosity filling agent in various food and beverage .It can not only enhance the performance of water-keeping and shape-keeping, but also improve the freeze/thaw stability and taste of food and beverage products. Meanwhile, Xanthan Gum can extend the shelf life of products, simplifying the filling and sterilization during the course of production and save lots of production cost and increase the profit rate.

　　Oil Drilling & Exploitation Grade

　　Oil Drilling & Exploitation Grade Xanthan Gum is specially produced as mud additive for oil drilling and exploitation. Being an environment friendly and high efficiency mud additive, Oil Drilling & Exploitation Grade Xanthan Gum has an excellent tolerance to the changes of temperature, acid, alkaline and salt. Meanwhile, it can extremely increase the products penetrating ability and suspending performance to small solid materials, and reduce the pressure loss during drilling. This Xanthan gum can not only fasten the well bore, but decrease the damage to oil formation. It can also greatly raise the efficiency of drilling, repair and completion. As a biotype oil driver, Oil Drilling & Exploitation Grade Xanthan Gum can improve oil extraction rate and utilization factor of natural resources. The more important point is that it can furthest protect natural environment.
