Abstract: In the preparation of a dry, stable, phosphoric acid acidulated beverage mix, heretofore, a phosphoric acid chemical stabilizer was required due to the notorious hygroscopicity of H.sub.3 PO.sub.4, particularly in fructose sweetened systems. This invention eliminates the need for such stabilizers via the employment of pulverized crystalline sugar for improved structural stability, faster solubility and non-hygroscopicity of the dry beverage mix heretofore unknown in the art. The dry beverage mix of the present invention rapidly dissolves in aqueous solution which may be carbonated to form colas, root beers, sarsaparillas or any other beverage which contains phosphoric acid as a flavoring ingredient and acidulent. This dry beverage mix is made via vacuum drying a uniform slurry of the pulverized sugar, liquid flavorant and phosphoric acid acidulent.
