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 zinc oxide was also prepared in a separate container by thoroughly mixing 81.38 g of zinc oxide in 25 mL of water. An aqueous solution of calcium hydroxide was also prepared in a separate container by thoroughly mixing 74.09 g of calcium hydroxide in 25 mL of water. The zinc oxide solution and the calcium hydroxide solution were then slowly added to the malic acid solution. The resulting solution was then spray dried to produce a powdered dihydroxycalcium zinc malate (or calciumhydroxy zinchydroxy malate).
