Summary:There is disclosed a novel process for preparing hemipotassium phosphate useful as an acidulant for beverages. An equimolar mixture of monopotassium phosphate and phosphoric acid is heated to a temperature above 100 DEG C. cooled with vigorous agitation whereby the liquid loses its free water and crystallizes to a relatively dry crystalline mass. When prepared by the process of this invention hemipotassium phosphate provides a dry, flowable, crystalline product which can be transported and handled easily.
