Abstract
Anion exchange resin was used to extract phytic acid and measure iron pectrophotometric method was adopted to determine phytic acid concentration.The results showed that:Extraction time,extraction temperature,resin type and flow rate were main influencing factors.The optimal craft were that extraction temperature was 45℃,extraction time was 3 h,D201 anion exchange resin was adapted to disassociation,flow rate was 1 mL per min.Phytic acid content were 70.39 mg·g-1 and 21.14 mg·g-1 by the method in the rice and bean pulp respectively.It could be concluded that the extraction method was effective and the assay method was simple,accurate,they were adapt to extraction and determine the phytic acid in the agriculture by-product.
