Abstract: This paper mainly discussed how to extract phytase from bran. And the activities of wheat bran phytase were studied.The optimum conditions for this extraction of phytase were: pH 5.15 and temperature 37℃. Inositol triphosphate was obtainedthrough partially hydrolyzing phytic acid and isolated by ion exchange resin. This provided a feasible way to produce inositoltriphosphate.

Key words: phytic acid, phytase, wheat bran, inositol triphoshate
