This study was conducted to investigate the quality characteristics of Jeolpyun prepared with different percentages of lotus leaf powder for 4 days. The moisture content of Jeolpyun without lotus leaf powder was 50.63% and those of Jeolpyun with the powder were 50.17～52.63% on 0 day; however, they did not show constant tendency during storage. Total cell counts of Jeolpyun with lotus leaf powder increased less than those of Jeolpyun without the powder during storage. As lotus leaf powder increased, L values of lotus leaf Jeolpyun significantly decreased and their a values significantly increased. As storage time increased, L values of lotus leaf Jeolpyun increased, and a and b values did not show constant tendency during storage. There was no difference between Jeolpyun with lotus leaf powder and Jeolpyun without the powder in hardness and chewiness on 0 day. As lotus leaf powder increased, the hardness and chewiness of lotus leaf Jeolpyun decreased after 1 day. The adhesiveness of 0% lotus leaf Jeolpyun significantly decreased after 2 days, and there was no difference in adhesiveness except for 3% lotus leaf Jeolpyun by 2 days. The springiness of 2% and 3% lotus leaf Jeolpyun was not significantly different for 4 days and the gumminess of all samples increased after 2 days. There was significant difference in cohesiveness between Jeolpyun with lotus leaf powder and Jeolpyun without on 0 day, but there was no great difference during storage. In the sensory evaluation, 2% lotus leaf Jeolpyun showed the highest preference scores; hence, 2% lotus leaf Jeolpyun prepared with 980 g rice flour, 20 g lotus leaf powder, 10 g salt and 360 g water was picked as the best.
