In this study, the antioxidant activity and quality characteristics of the Korean traditional food jeung-pyun made with ju-bak powder were investigated. Jeung-pyun added with 10% ju-bak powder had a total polyphenol content of 54.27%, DPPH free radical scavenging activity of 91.98%, reducing power of 0.51% and SOD-like antioxidant activity of 18.21%. Jeung-pyun added with ju-bak powder had a moisture content of 52.65 to 46.94%, crude fat content of 1.61 to 1.29%, crude protein content of 3.50 to 4.66%, crude ash content of 0.68 to 0.82% and dietary fiber content of 0.12 to 1.46%. Ju-bak powder added with jeung-pyun had a pH level from 4.86 to 4.39. As ju-bak content increased, the pH decreased significantly. Color L value were 78.82 to 68.67. As ju-bak content increased, the Color L value content decreased significantly; a value ranged from ?1.89 to 0.69 and b value from 2.99 to 14.25. As ju-bak content increased, the color content significantly increased. As ju-bak content increased, the volume significantly decreased (ranged from 42.50 to 30.00 mL), hardness, gumminess and chewiness significantly increased, and cohesiveness significantly decreased. From SEM, as ju-bak content increased, the pores merged and collapsed, whereas the number of pores decreased and pore size became larger. Sensory evaluation of color, flavor, taste, texture, appearance, cell uniformity and overall acceptability for various levels of ju-bak powder showed that 10% had the highest acceptability. Therefore, 10% ju-bak power added with jeung-pyun has both high antioxidant capacity and sensory acceptability.
