Abstract: 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.
Abstract: A nonhygroscopic pulverulent composition for preparing beverages with a lasting effervescence comprises a first component or group of components mixed with a second component or group of components capable of reacting mutually in the presence of water to evolve a gas. Each of said components or group of components is impregnated with the dry residue of a saccharose liquor or of a saccharose derivative liquor containing a water-soluble or a mixture of water-soluble polymers.
