The objective of this study was to investigate an influence of the degree of hotness of powdered red pepper on quality attributes of Kimchi. The extent of hotness was analysed by content of capsaicin and dihydrocapsaicin and ASTA color value, and the change of quality attributes of samples were evaluated by pH, acidity, total microbes, lactic acid bacteria cell count and sensory. Content of capsaicin and dihydrocapsaicin in mild red pepper powder was 11.4mg%, 5.4mg% respectively. And content of capsaicin and dihydrocapsaicin in hot red pepper powder was 149.1mg%, 66.0mg% respectively. Kimchi was made with mild and hot red pepper and stored for 24 days at 5±1℃. The pH of Kimchi made with mild red pepper powder during storage of 12 days was slightly lower than that of Kimchi with hot red pepper powder. The pattern of change in pH of samples showed a reducing trend during storage, and the acidity was vice-versa. At day 0, numbers of total bacteria in mild and hot Kimchi were 5.7, 6.7 log cfu/g, respectively. And at day 3, number of total bacteria in mild and hot Kimchi was same. The change in number of lactic acid bacteria was similar to that of total bacteria. In case of sensory evaluation, Kimchi made with hot red pepper powder showed better sensory scores in overall acceptability.
