The purpose of this study was to investigate quality characteristics of roll bread with the addition of Chungkukjang powder(0, 5, 10, 15, 20%). The antioxidative activity of antioxidative substances produced from several bacterial strains isolated from fermented foods were tested by DPPH $(alpha,alpha’-diphenyl-eta-picrylhydrazyl)$ free radical scavenging activity. The most optimal medium condition for the production of antioxidative substance from Bacillus sp. FF-7 was 2% galactose as carbon source and 1% tryptone as nitrogen source. In color values, with increasing Chungkukjang powder content, the "lightness" (p<0.05) decreased in the crumb bread, while the redness(p<0.05) and yellowness(p<0.05) increased. The volume and specific volume of roll bread with 5.0% Chungkukjang powder were the highest(p<0.05). In the rheology measurements for the roll bread, the hardness (p<0.05) decreased with the addition of 5.0% Chungkukjang powder, but then increased with further additions of Chungkukjang up to 10.0%. Highest sensory scores for color, flavor, taste(p<0.05), texture(p<0.05) and overall acceptance(p<0.05) were obtained from roll bread with 5.0% Chungkukjang powder and control. From the results of this study, it was assumed that the development of food products using Chungkukjang is prospective in response to health-oriented consumers.
