Abstract: Powder compositions comprising alkali metal bicarbonate particles and an additive. A process for preparing alkali metal bicarbonate particles by spray-drying of an aqueous solution or suspension comprising 1-10% by weight of alkali metal bicarbonate and a resin acid or a fatty acid as additive. A process for preparing alkali metal bicarbonate particles by co-grinding the alkali metal bicarbonate in the presence of a resin acid as additive. A process for preparing alkali metal bicarbonate particles by fluidized bed coating of the alkali metal bicarbonate in the presence of a resin acid, fatty acid or a wax as additive.
