Process for converting phytate into inorganic phosphate

摘要

The present invention relates to a process 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 to 1000 parts by weight of a solvent mixture which comprises water and a water-immiscible organic solvent having a boiling point of 20 to 100 degC, the water-immiscible organic solvent constituting 20 to 85 percent by weight of the solvent mixture, and (c) a phytase; and (ii) drying the food in order 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.
