Xanthan Gum

Xanthan gum is a polysaccharide used as a food additive and rheology modifier (Davidson ch. 24). It is produced by a process involving fermentation of glucose or sucrose by the Xanthomonas campestris bacterium.

Xanthan gum is a polysaccharide used as a food additive and rheology modifier (Davidson ch. 24). It is produced by a process involving fermentation of glucose or sucrose by the Xanthomonas campestris bacterium.
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.
