Water-soluble, natural-dietary zinc source was prepared by extracting zinc from defatted wheat germ via enzymatic degradation using amylase and protease under acidic condition. Zinc was recovered as a precipitate by altering the pH. Precipitated zinc-containing fraction was dissolved with citric acid and spray-dried to make wheat germ extract, WG-P, with zinc content of 1610 mg/kg. Zinc in WG-P was water-soluble in both acidic and alkaline pH range.
