It is produced by a process involving
fermentation of glucose or sucrose by the Xanthomonas campestris
bacterium.
One of the most remarkable properties of xanthan gum is its
capability of producing a large increase in the viscosity of a
liquid by adding a very small quantity of gum, on the order of
one percent. In most foods, it is used at 0.5% and can be used in
lower concentrations. The viscosity of xanthan gum solutions
decreases with higher shear rates; This is called
pseudoplasticity. This means that a product subjected to shear,
whether from mixing, shaking or even chewing, will thin out, but
once the shear forces are removed, the food will thicken back up.
A practical use would be in salad dressing: The xanthan gum makes
it thick enough at rest in the bottle to keep the mixture fairly
homogeneous, but the shear forces generated by shaking and
pouring thins it so it can be easily poured. When it exits the
bottle, the shear forces are removed and it thickens back up so
it clings to the salad. Unlike other gums, it is very stable
under a wide range of temperatures and pH.
In foods, xanthan gum is most often found in salad dressings and
sauces. It helps to stabilize the colloidal oil and solid
components against creaming by acting as an emulsifier. Also used
in frozen foods and beverages, xanthan gum creates the pleasant
texture in many ice creams. Toothpaste often contains xanthan
gum, where it serves as a binder to keep the product uniform.
Xanthan gum is also used in gluten-free baking. Since the gluten
found in wheat must be omitted, xanthan gum is used to give the
dough or batter a "stickiness" that would otherwise be achieved
with the gluten. Xanthan gum also helps thicken commercial egg
substitutes made from egg whites to replace the fat and
emulsifiers found in yolks. It is also a preferred method of
thickening liquids for those with swallowing disorders, since it
does not change the color or flavor of foods or beverages.
In the oil industry, xanthan gum is used in large quantities,
usually to thicken drilling fluids. These fluids serve to carry
the solids cut by the drilling bit back to the surface. Xanthan
gum provides great "low end" rheology. When the circulation
stops, the solids still remain suspended in the drilling fluid.
The widespread use of horizontal drilling and the demand for good
control of drilled solids has led to the expanded use of xanthan
gum. Xanthan gum has also been added to concrete poured
underwater, in order to increase its viscosity and prevent
washout.
In cosmetics xanthan gum is used to prepare water gels usually in
conjunction with bentonite clays. Is also used in oil-in-water
emulsions to help stabilise the oil droplets against coalescence.
It has some skin hydrating properties.
