Abstract

In this study, physio-chemical, mechanical, and sensory characteristics of Tofu containing 0, 0.5, 1.0, and 2.0% Adenophora remotiflora powder were examined. In addition, we examined the potential of utilizing Adenophora remotiflora powder as a functional food material by estimating total phenol contents, electron-donating abilities, and hydroxyl radical scavenging activities of the hot water and ethanol extracts of Adenophora remotiflora powder in the range from 0~2.0%. The total phenol content of the ethanol extracts of Adenophora remotiflora powder was $487.93{\mu}g/mL$ while the that of the water extract of Adenophora remotiflora powder was $403.70{\mu}/mL$. The electron-donating abilities of the ethanol and water extracts of Adenophora remotiflora powder were 75.37 and 86.10%, respectively. The hydroxyl radical scavenging activities of the ethanol and water extracts of Adenophora remotiflora powder were 65.50 and 66.22%, respectively. We also evaluated the quality characteristics of Tofu containing Adenophora remotiflora powder. In the case of color values, as the level of Adenophora remotiflora powder increased, the values of L (lightness) and a (redness) decreased, whereas that of b (yellowness) increased. In the case of mechanical properties, as the level of Adenophora remotiflora powder increased, hardness, gumminess, and chewiness values increased (p<0.05), whereas springiness and cohesiveness values decreased (p<0.05). In the case of sensory evaluation, MPT1.0 scored significantly higher in color, flavor, tenderness, texture, and overall quality. To sum up, Tofu containing 1% Adenophora remotiflora powder showed the highest overall preference.
