Procedure

An aqueous solution of malic acid was prepared by mixing 134.09 g of malic acid with 50 mL of water. An aqueous solution of calcium carbonate was also prepared in a separate container by thoroughly mixing 200.18 g of calcium carbonate in 50 mL of water. The calcium carbonate solution was then slowly added to the malic acid solution. The resulting solution was spray dried to produce a powdered dicalciumhydroxy malate.
