Summary:The invention leads to powder compositions comprising alkali metal bicarbonate particles and an amino acid as additive. The invention also relates to a process for preparing alkali metal bicarbonate particles by spray-drying of an aqueous solution comprising 1 - 10 % by weight of alkali metal bicarbonate and an amino acid as additive. The invention furthermore relates to a process for preparing alkali metal bicarbonate particles by co-grinding the alkali metal bicarbonate in the presence of an amino acid as additive. La présente invention concerne des compositions pulvérulentes comprenant des particules de bicarbonate de métal alcalin et un acide aminé comme additif. L'invention concerne également un procédé de préparation de particules de bicarbonate de métal alcalin par séchage par pulvérisation d'une solution aqueuse comprenant 1 à 10 % en poids de bicarbonate de métal alcalin et un acide aminé comme additif. L'invention concerne en outre un procédé de préparation de particules de bicarbonate de métal alcalin par co-broyage du bicarbonate de métal alcalin en présence d'un acide aminé comme additif.
