초록
This study was carried out to investigate the effects of adding prickly pear (Opuntia ficus-india var. Sabolen) on the quality characteristics of Jeung-Pyun, a traditional fermented Korean rice cake, and to find out an appropriate ratio of prickly pear powder to give a favorable color. Changes in the quality characteristics of prickly pear-added Jeung-Pyun during storage period were also studied. As the addition of prickly pear powder was increased from 1 to 3%, the degrees of expansion and gelatinization of Jeung-Pyun were increased. The degree of gelatinization and hardness were changed slowly during storage at room temperature (20$^{\circ}C$). In sensory evaluation, control Jeung-Pyun samples without prickly pear powder was preferred to that with prickly pear powder, but it was not significant up to 2% prickly pear powder. In the case of Jeung-Pyun containing 2% prickly pear powder, those stored for 12 hr received higher sensory scores than those right after being manufactured. In general, Jeung-Pyun samples with 2% prickly pear powder was favored. The addition of prickly pear powder was likely to improve the preservation property of Jeung-Pyun.
