This study was conducted to investigate the physicochemical and sensory characteristics of yanggaeng prepared with Curcuma longa L. powder(CP; 0, 0.5, 1, 1.5, 2%). Increasing the amount of CP in the yanggaeng tended to increase the moisture content and pH value, while it decreased the $^{circ}brix$ value. Increasing the amount of CP in the yanggaeng also tended to decrease the lightness(L) in the hunter color values, increasing the redness(a) and yellowness(b). For the textural characteristics, the addition of CP decreased the hardness, adhesiveness, springiness, gumminess and brittleness. In sensory evaluation, yanggaeng added with 1% CP had excellent scores in sensory preference. Based on the results, 1% should be recommended as the optimum level of CP to be added for the preparation of yanggaeng.
