[ Objective ] Optimization of process conditions for preparation of phytic acid from lees extract phytin. [ Method ] Through the 732# cation exchange resin and 717# anion exchange resin adsorption for preparing dilute phytic acid, using active carbon for decolorlng, method of vacuum pressure reduction, high quality phytic acid was prepared. [ Result] Phytic acid preparation conditions： The optimal velocity of 732# cation exchange resin is 375 ml/h, the maximum amount of sample is 0.5 ml. The best velocity of 717# anion exchange resin for 250 ml/h, the maximum amount of sample is 0.5 ml. The optimum conditions for activated carbon decolorization ： 0.5 ml/min, the temperature is 60 ℃. Vacuum concentration temperature is 50 ℃. [ Conclusion] The experiment determined the optimum conditions of phytic acid were prepared by exchanging lees extract phytin system resin by ion, provides an important basis for the industrial production of preparing a lot of phytic acid.
