Xanthan Gum
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.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
-120℃ temperature and 2-12PH, xanthan gum keeps 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
1、 Function
Introduction:
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.

1、 Function
Introduction:
Acting as thickener and stabilizer, Industrial
Grade Xanthan Gum can be applied to many industrial fields, such as pesticide, feedstuff,
porrery & porcelain, printing & dyeing, paint & dope, paper-making,
minextraction, and so on. It can prolong the products using-life and increase
the sticking & oxidation resistance properties. Furthermore, Industrial
Grade Xanthan Gum can save the consumption of other materials and make the
products color-clear, bright and clean.

1、Function
Introduction:
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,
alaline and salt. Meanwhile, it can extremely increase the products penetrating
ability and suspending perform 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.
