Xanthan Gum is a high molecular weight polysaccharide which is produced by fermentation of Xanthomonas campestris.The main functional property of Xanthan gum is the ability to control the rheology of water-based systems. Xanthan Gum solutions are highly pseudoplastic, their viscosity is reduced instantly when high shear rates are applied. This property allows easy pumping and spraying. In contrast a high viscosity at lower shear rates gives excellent ability to stabilise emulsions, suspensions and foams.
