A non-hygroscopic water-soluble pulverulent composition for the preparation of drinks which release gas over a prolonged period comprises a mixture of a first constituent with a second constituent which react with one another in the presence of water to release gas, each of the said constituents being coated or impregnated with a film comprising xanthan gum. The coating is carried out using aqueous solutions of xanthan gum to which sucrose or sucrose derivatives have been added if necessary. |
