Oxygen radical absorbance capacity (ORAC) and cellular antioxidant activity (CAA) in extracts of mature wheat bran (MWB), immature wheat bran (IWB), and steamed immature wheat bran (SIWB).
| Antioxidant Capacity | MWB | IWB | SIWB | |
|---|---|---|---|---|
| ORAC 1 (µM TE/g) | Free *** | 44 ± 3.9 ab | 54 ± 8.3 a | 38 ± 3.6 b |
| Bound *** | 237 ± 4.7 b | 273 ± 13 a | 252 ± 17 ab | |
| Total 2,*** | 281 ± 4.7 b | 327 ± 11 a | 290 ± 20 b | |
| CAA 1,*** (µM QE/g) | 0.63 ± 0.07 c | 4.59 ± 0.17 a | 2.58 ± 0.47 b | |
1 Mean values of three replications; 2 Total was calculated as a sum of free and bound values; abc Values with same alphabet within a row are not significantly different; *** Significantly differ at p < 0.001.
