Abstract
Fumed silica is added to xanthan gum beer prior to normal isolation procedures. The xanthan gum obtained from this beer is characterized in that it is more readily dispersible than xanthan gum from regular beer. This dispersible xanthan gum does not require vigorous agitation to attain homogenous, lump-free solutions.

A process for producing a dispersible xanthan gum composite consisting essentially of xanthan gum and silica wherein the ratio xanthan gum to silica ranges from about 19:1 to 1:1 which comprises:
- (a) adding silica to a xanthan gum solution,
- (b) then isolating said composite from said solution, and
- (c) drying and milling the isolated composite.
