Abstract

In making a sugar preparation which is readily soluble, without sitrring, in water and beverages such as tea and coffee and comprises ingredients which, in the presence of more than 8% of their dry weight of water, react to liberate a gas, an aqueous solution of sugar is intimately mixed with one or more gas-evolving substances and the mixture is dried, e.g. atomized, in a current of hot air, to form grains, which are then mixed with one or more acidic reagents. Alternatively, sugar is mixed with one or more gas-evolving substances, one or more acidic reagents and not more than 8% of water, based on the dry weight of the ingredients, and the mixture is granulated and dried, e.g. at 50 DEG C. The sugar preparation should, preferably, contain at least 5%, by weight, of the gas-evolving substance or substances based on its sugar content. The amount of the acidic reagent or reagents may be at least the stoichiometric equivalent of the gas-evolving substance or substances. Specified gas-evolving substances are: sodium bicarbonate, e.g. mixed with calcium carbonate, and sodium carbonate. Specified acidic reagents are phosphoric acid, an alkali metal pyrophosphate and a mixture of citric and tartaric acids. The sugar preparation may comprise edible colouring matter and powdered flavouring and may be added to ice-water to form an effervescent beverage.
