Manufacturing method for phytin or phytic acid using rice bran

摘要

PURPOSE: A process for preparing phytin or phytic acid using rice bran is provided, thereby preparing cheap phytin or phytic acid in higher purity and yield. CONSTITUTION: A process for preparing phytin or phytic acid using rice bran comprises the steps of: (a) mixing rice bran with an acid solution to pH 2 to 4 to extract phytin from rice bran; (b) separating the mixture of the step (a) into the supernatant and sludge; and (c) adding an alkali solution into the supernatant of the step (b) to neutralize the supernatant and heating the neutralized solution at 50 to 55 deg. C to precipitate phytin.
