Process for converting phytate into inorganic phosphate

摘要

A process is provided for converting phytate in a food into inorganic phosphate. The process comprises the steps of:(i) mechanically mixing a slurry comprising:(a) 100 parts by weight of the phytate-containing food,(b) 60-1000 parts by weight of a solvent mixture which comprises water and a water-immiscible organic solvent having a boiling point of 20-100° C., the water-immiscible organic solvent constituting 20-85% by wt. of the solvent mixture, and(c) a phytase; and(ii) drying the food to remove the organic solvent.The process has the advantage of enabling a high conversion rate of phytate into inorganic phosphate in an economical manner.
