This study was conducted to investigate the effect of fresh ginseng on the physicochemical, microbiological and sensory properties of Nabak-kimchi during 33 day fermentation. Nabak-kimchi with the various levels (0, 2, 4, 6％) of fresh ginseng were fermented at 4$^{circ}C$. During the fermentation, pH was lowered in all Nabak-kimchi samples and pH of Nabak-kimchi added fresh ginseng was a little lower than that of Nabak-kimchi without fresh ginseng. Acidity increased continuously during the entire fermentation. Saltiness was maintained at 1.60-1.67% levels during the whole fermentation. Total vitamin C contents increased drastically on the first day of fermentation and decreased after the first day and then increased during 21-24 day fermentation. Total bacteria increased rapidly at the beginning of fermentation and reached its maximum number on 6th day offermentation and then decreased slowly. Total bacteria of Nabak-kimchi added fresh ginseng was highly main-tained during the entire fermentation periods. As a result of the sensory evaluation, Nabak-kimchi added 4% fresh ginseng was the most palatable one.
