Abstract
There is disclosed a process for producing purified xanthan gum, which comprises (i) adding a hydrophilic organic solvent to an aqueous solution containing crude xanthan gum with pH 0.5 to 2.5, and (ii) neutralizing the mixture with a base to precipitate the xanthan gum. The xanthan gum thus obtained has low contents of ash and remaining organic solvent, as well as a high quality with little impurities, and can advantageously be used in the fields of foods, cosmetics, medicaments and the like.
