The quality characteristics of the bread prepared with black soybean powder(BSP) were evaluated. Breads were prepared by the addition of 0, 5, 10, 15, and 20％ of BSP to the basic formulation. The pH's of dough with BSP were ranged from 5.13 to 5.77 and that of the control was 5.43. The volume of dough, loaf volume and loaf volume index of the bread with 5％-BSP was the highest. The peak viscosity of the doughs with BSP (200~545 BU) measured by the Amylograph were lower than that of the control (1077 BU). Color $L^{*}$ value of the bread crust and crumb with BSP decreased, and color $a^{*}$ values of the bread crumb with BSP increased, but $a^{*}$ and $b^{*}$ values of the crust with BSP decreased. The hardness, cohesiveness, springiness, and gumminess increased as the concentration of BSP increased. Degree of retrogradations(2.60~4.07) of the bread with BSP was lower than that(6.00) of the control after 48 hrs. From the result of the sensory evaluation, the overall quality score of the bread with 5％-BSP, 4.37, was the highest among samples compared with.ith.ith.
