• Xanthan gum product application:

• Food field:
  In foods, xanthan gum is most often found in salad dressings and sauces.Xanthan gum also helps suspend solid particles, such as spices. Also used in frozen foods and beverages, xanthan gum helps create the pleasant texture in many ice creams, along with guar gum and locust bean gum.Xanthan gum is also used in gluten-freebaking. 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.Industry field:In the oil industry, xanthan gum is used in large quantities, usually to thicken drilling mud. 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 its expanded use. It has also been added to concrete poured underwater, to increase its viscosity and prevent washout.
