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 162.78 g of zinc oxide in 50 mL of water. The zinc oxide solution was then slowly added to the malic acid solution. The resulting solution was spray dried to produce a powdered dizinchydroxy malate.
