본 발명은 알칼리 금속 중탄산염 입자 및 첨가제로서 아미노산을 포함하는 분말 조성물에 관한 것이다. 본 발명은 또한 1 중량% 내지 10 중량%의 알칼리 금속 중탄산염 및 첨가제로서 아미노산을 포함하는 수용액의 분무 건조에 의해 알칼리 금속 중탄산염 입자를 제조하는 방법에 관한 것이다. 본 방법은 나아가, 첨가제로서 아미노산 존재 하에서 알칼리 금속 중탄산염을 공동-분쇄시킴으로써 알칼리 금속 중탄산염 입자를 제조하는 방법에 관한 것이다. 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.
