One aspect of the present invention relates to a readily water-dispersible particulate composition comprising by weight of dry matter at least 10% of xanthan gum and not more than 60% of starch, said composition being characterized in that the xanthan gum present in the composition can be dispersed completely within 2 minutes in distilled water of 25° C. at a concentration of 0.7% based on the dry weight of xanthan. The particulate xanthan gum compositions of the present invention exhibit unique viscosity enhancing properties that are dependent on the electrolyte levels of the aqueous environment in which they are applied. The favorable properties of the xanthan compositions according to the invention can be realized without resorting to chemical modification of the xanthan gum. The xanthan compositions according to the present invention can be applied advantageously in e.g. food products and oil drilling fluids.
