Xanthan gum, also known as yellow gum, Hanseong gum, xanthomonas polysaccharide, is a kind of monopolysaccharide produced by pseudxanthomonas SPP fermentation. Xanthomonas brassicola takes carbohydrates as the main raw materials, and through aerobic fermentation bioengineering technology, 1, 6-glucoside bond is cut off, spending chain is made, and straight chain is synthesized by 1, 4-bond. In 1952, Xanomonas brassica was isolated by the U.S. Department of Agriculture's Northern Research Institute in Pioriel, Illinois, and was obtained by converting cabbage extract into water-soluble acidic extracellular heterosaccharides.
1,Xanthan Gum in food :
xanthan gum is most often found in salad dressings and sauces. It helps to prevent oil separation by stabilizing the emulsion, although it is not an emulsifier. Xanthan gum also helps suspend solid particles, such as spices. Xanthan gum helps create the pleasant texture in many ice creams, along with guar gum and locust bean gum.
2,Xanthan Gum in oil industry :
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.
