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.
La présente invention concerne un procédé de transformation de phytate contenu dans un aliment en phosphate inorganique. Ce procédé consiste à: (i) mélanger mécaniquement un coulis renfermant: (a) 100 parties en poids de l'aliment contenant le phytate, (b) 60-1000 parties en poids d'un mélange de solvant renfermant de l'eau et un solvant organique non miscible dans l'eau dont le point d'ébullition se situe entre 20 et 100 DEG C, ce solvant organique non miscible dans l'eau constituant entre 20 et 85 % en poids du mélange de solvant; et (c) une phytase; ce procédé consistant ensuite à (ii) sécher l'aliment pour en éliminer le solvant organique. Par ailleurs, ce procédé a l'avantage de permettre une transformation rapide du phytate en phosphate non organique de façon économique.
