Abstract
The aim was to optimize the degradation of phytic acid of wheat bran. Hydrochloric acid degradation of phytic acid was used to investigate the concentration of hydrochloric acid,ratio of solid to liquid,time and temperature were studied. According to single factor experiment,the optimum conditions showed that when the time of 2.5 h,temperature of 52 ℃,the concentration of hydrochloric acid of 1.2 mol / L,the ratio of solid to liquid1∶ 21 g / m L,the residual amount of phytic acid reduced to 0.625% by Box- benhnken.It showed that the method of hydrochloric acid degradation was a better method.
