  • Carbonating agents and their preparation
    Patent number: 4760138
    Abstract: Dry, stable carbonating agents comprised of a carbohydrate/metal bicarbonate complex are disclosed. The complex is prepared by reacting a carbohydrate with a metal hydroxide or oxide at a temperature not exceeding 25.degree. C. to form a carbohydrate/metal hydroxide adduct to which carbon dioxide is then introduced to form the complex. The complex is then immediately dried, preferably by freeze drying. The carbonating agents are particularly useful as components of dehydrated beverage powders. Upon rehydration, the complex releases carbon dioxide and carbonates the beverage. Additionally, upon rehydration the complex promotes the solubilization of the carbohydrate components in the beverage.
