3.3. Evaluation of the analytical procedure for purification of phytic acid in rice bran
The purified PA was characterized to evaluate the efficiency of the procedure (Table 6). The phytic P content of the standard PA was 124.86 ± 2.78 mg g−1 and of the purified PA was 64.63 ± 2.77 mg g−1, which corresponded to 94.12 g 100 g−1 and 62.21 g 100 g−1 of total P. The inorganic P content was 0.01 ± 0.00 mg g−1 and 0.11 ± 0.00 mg g−1 PA, respectively.
