This study was performed to compare the contents of nutrients and taste components in Korean(King and Dabok) and imported(from Myanma) red pepper powders. Red pepper imported from Myanma was narrower and lighter and showed significantly higher contents of moisture and lipid. Lower amount of fructose and glucose shown in imported red pepper powder seemed related to lower sensory score in sweet taste. Capsaicin was contained much higher in imported red pepper powder and looked related to higher score in pungent tastes. Organic acids like oxalic acid, malonic acid, succinic acid, pyroglutamic acid were significantly lower in imported red pepper powder. Imported red pepper powder showed lower amount of $eta$-carotene, capsanthin and color value(L, a, b) than Dabok and obtained lower sensory score in color.
