The invention discloses a process for producing phytic acid of rice bran, which comprises the following steps: sieving rice bran meal after grinding and hydrolysing it with glutamic acid decarboxylase, separating a supernatant and a residue; once again the residue is hydrolysate with glutamic decarboxylase, two supernatants and two residues are obtained again, and a supernatant and two times are obtained. The supernatant is combined with the total liquid of the supernatant, adjusting the pH value and concentrating the total liquid of the supernatant until the weight of the solution is 2% of the weight of the solution before the concentration of 5%, and the static is 1 for 2 hours, and it is separated again, and three supernatants and three slag are obtained. The three supernatants are separated after the membrane separation and then the phytic acid is extracted, then four supernatants are separated and then the supernatant is obtained and then obtained the supernatant and four times of supernatant and Four slag, the four supernatant was enzymase, five supernatant and five residue were separated. The five slag was dried and dried to produce crude calcium phytate. After refining, the phytic acid was obtained by ion exchange and decolorization. The preparation technology of rice bran phytic acid has the advantages of high purity, high yield, no pollution to the environment and simple manufacturing method.
