The aim of this study was to investigate the effect of black lentil flour (BLF) on the quality of wheat bread. The control bread with wheat flour and BLF-supplemented breads (2, 6 and 10 %, respectively) were prepared and analyzed in terms of proximate composition, physicochemical and sensorial properties, total phenolic content (TPC), and antioxidant activity. The BLF-supplemented breads provided significantly higher protein compared to the control bread (p < 0.05). Moreover, it improved significantly TPC and antioxidant capacity (p < 0.05). However, the addition of BLF reduced significantly the specific volume of the bread, L* and b* values of both crumb and crust (p < 0.05). The BLF had no influence overall acceptability. Our findings revealed that the BLF may a have potential use to enhance the quality of wheat bread.
