The purpose of this study was to determine the optimal mixing ratio of hot-air dried loquat leaf powder and optimum conditions for making Jeolpyun containing hot-air dried loquat leaf powder (LLP). Samples of Jeolpyun were prepared with different contents of hot-air dried LLP (0%, 3%, 6%, 9%, 12%) followed by analysis of chemical properties, moisture contents, color, mechanical quality characteristics, amylograph, and sensory tests. Chemical analysis showed that hot-air dried LLP consisted of 11.41% water, 8.34% crude protein, 1.90% crude fat, 7.74% crude ash, and 16.95% crude fiber, with ?Brix of 2.07, and pH of 5.78. Moisture contents of samples ranged from 52.22 to 50.06%. L-value decreased with addition of hot-air dried LLP, whereas a-value increased with increasing amount of hot-air dried LLP, and no significant differences were observed regarding b-value. In the mechanical evaluation of physical properties, hardness deceased with increasing amount of hot-air dried LLP. The starting temperature amylograph of Jeolpyun was higher in samples with hot-air dried LLP than those without hot-air dried LLP. Set back was slower with increasing amount of hot-air dried LLP, an increasing amount of hot-air dried LLP made set back of Jeolpyun slower. In the sensory test, Jeolpyun with 6% hot-air dried LLP was the most preferred with less bitterness and proper softness, moisture and chewiness. Therefore, addition of 6% hot-air dried LLP to Jeolpyun made with rice flour showed the best overall preference. Based on the results of this experiment, samples with hot-air dried LLP showed slower hardening than those without hot-air dried LLP in textural changes during storage, and Jeolpyun with 6% hot-air dried LLP is expected to increase quality and preference of Jeolpyun.
