This study was carried out to investigate the quality characteristics and antioxidant activity of the black sesame Dasikadded spirulina (0, 10, 20, 30%). Black sesame Dasik with 30% spirulina showed a higher moisture content compared to control. L, a and b values of Hunter color system were decreased significantly according to the addition of spirulina (p<0.05). Hardness and gumminess analyzed by TPA (Texture profile analyzer) were increased significantly according to the addition of spirulina (p<0.05). The antioxidant property of black sesame Dasik increased according to the addition of spirulina: IC50 values of DPPH (1,1-diphenyl-2-picrylhydrazyl) and hydroxyl radical scavenging activity of the control was 112.3 g/mL and 56.2 mg/mL, respectively, whereas those of Dasik with 30% addition of spirulina was 58.2 mg/mL and 45.7 mg/mL, respectively. Sensory evaluation results showed that the overall acceptability was not significantly different up to 20% addition of spirulina, compared to that of the control. Based on these results, it was suggested that the addition of spirulina to black sesame Dasik was appropriated up to 20% for quality improvement with antioxidant activity.
