This study aimed to screen the effective parameters that influence the extraction of phytic acid from defatted rice bran. Phytic acid was extracted from defatted rice bran with the help of food-grade acetic acid. The extraction parameters were screened in accordance with the Plackett–Burman design methodology to investigate their effects on the yield of phytic acid. A mathematical model of the yield of phytic acid was developed according to the statistical results of different parameters. This paper studied the main effects and the ratio of liquid to solid (L/S ratio), and at the same time pH and temperature were found to be the significant parameters on the yield of phytic acid. With the optimized parameters from the established mathematical model, this paper carried out a validation of the model.
