xanthan gum

Product Description

GENERAL INFORMATION
Xanthan gum is a high molecular weight polysaccharide. In the late fifties the research laboratories of the US Department of Agriculture discovered that the bacterium Xanthomonas campestris found on cabbage plants produces a polysaccaride with exceptional properties. It is used as a rheology control agent in aqueous systems and as a stabilizer for emulsions and suspensions. Its numerous areas of applications cover a broad spectrum and rang from the food industry to oil recovery.
