This study examined the antioxidant activity and quality of Jeung-pyun prepared with different concentrations of hardy kiwi powder at 0%, 2.5%, 5%, 7.5%, and 10%. When the moisture content of Jeung-pyun was between 49.94-53.33%, the pH measurement showed a significant decrease with the increase of the hardy kiwi powder from 3.95 to 4.82. The L (lightness) values and the (redness) values decreased, whereas the b (yellowness) values increased with increasing amounts of hardy kiwi powder. The study showed a significant decrease in hardness, chewiness, and gumminess as the proportion of hardy kiwi powder in the Jeung-pyun increased. The total polyphenol content and DPPH radical scavenging activity increased noticeably as more hardy kiwi powder was added to the Jeung-pyun. As a result, the study groups with added hardy kiwi powder showed higher antioxidant activity than the control groups. Based on the results, this study recommends hardy kiwi as a good ingredient for enhancing the functionality of Jeung-pyun.
