The effect of wheat flour refined milling on nutritional and antioxidant quality of of two types of wheat (hard and soft) grown in Ethiopia was first evaluated. Then a recovery was attempted on bread prepared with the supplementation of the white wheat flour with different levels (0%, 10%, 20% and 25%) of wheat bran. Whole wheat flour (100% extraction) and white wheat flour (68% extraction) were subjected to proximate, mineral and antioxidant analysis. Results indicated that at low extraction rate (68%) the value of protein, fat, fiber, ash, Iron, zinc and phosphorous and antioxidant content of the samples were significantly affected (decreased) (P<0.05) by milling. The Total Phenolic Content (TPC) of white wheat flours, which ranged from 3.34 to 3.49 mg GAE/g were significantly lower (p<0.005) than those of whole wheat flours (ranging 7.66 to 8.20 G..
