Effects of onion peel extract and onion powder supplemented bread on SOD (a) and CAT (b) activities in the liver and kidney tissues of normal and experimental rats. NC = normal control, DC = diabetic control, OPE_1 = group fed with bread containing 1% onion peel extract, OPE_3 = group fed with bread containing 3% onion peel extract, OP_5 = group fed with bread containing 1% onion powder, OP_7 = group fed with bread containing 7% onion powder. *shows the significant difference compared with the diabetic control group (p < 0.01) via Dunnett’s multiple comparison test, while ‘ns’ shows a non-significant difference
