Antioxidant enzymes activities for copper zinc superoxide dismutase (CuZnSOD) and manganese superoxide dismutase (MnSOD) (A), glutathione peroxidase (GPx), and catalase (CAT) (B) were determined after treating Caco-2 cells with 500 μg/ml of Enprocal D and compared with other digested milk product controls. All data was compared with the levels of positive control (H2O2/Menadione). All treatments were performed in triplicate and assay was repeated three times independently with similar results. Data are expressed as mean ± SD. **P < 0.001 is the highly significant value from the control with media only. *P < 0.05 is the significance value from the control with media only.
