ALKALI METAL BICARBONATE PARTICLES WITH INCREASED DISSOLUTION TIME |
摘要 |
The invention relates to powder compositions comprising alkali metal bicarbonate particles and as additive. The invention also relates to 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. The invention further relates to a process for preparing alkali metal bicarbonate particles by co-grinding the alkali metal bicarbonate in the presence of a resin acid as additive. The invention also relates to 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. |
