This study investigated the antioxidative properties of Yangha Buds (Zingiber Mioga R) and quality characteristics of Korean steamed-rice cake, Sulgidduk, prepared with Yangha Buds juice. Antioxidative activities were measured based on DPPH radical and ABTS radical scavenging activities, total phenol content, and total flavonoid content in Yangha Buds (water extract and juice). Sulgidduk was prepared by adding Yangha buds at concentrations of 0, 1, 2, 3, and 4% of juice. To analyze quality characteristics, proximate composition, color, texture profiles, and sensory evaluations were measured. As content of Yangha buds juice increased, L-value significantly decreased while a-value and b-value increased (p<0.05). For texture profiles, control group scored higher score for hardness as compared to groups added with Yangha buds juice. Springiness, chewiness, and adhesiveness were not significantly different among the groups. In the sensory evaluation, samples containing 3% Yangha buds juice showed better results for attitude. Based on these results, we suggest that Yangha buds are a good ingredient for increasing consumer acceptability and functionality of Sulgidduk.
