The object of this study was to investigate the effects of blanching and lactic acid bacterial inoculation on the quality of kimchi. The pHs of the group added Leuconostoc mesenteroides were rapidly decreased, and then kept almost steady states. However, the pHs of the groups added Bifidobacterium bifidum were gradually decreased. Blanching treatment reduced the number of viable cells. At the beginning of the fermentation, the total organic acid contents of the blanched groups were lower than those of the non-blanched groups, but later on they were higher. With fermentation, the contents of malic, citric and fumaric acid were decreased in the control group, but increased in the cultured groups and all blanched groups. The cutting forces of the blanched groups were higher than those of the non-blanched groups during the whole fermentation period. The inoculation of Leu. mesenteroides was effective on the preservation of ascorbic acid. Blanching and the inoculation of Leu. mesenteroides gave good effect on the sensory acceptability. The acceptability of the groups added Bifidobacterium bifidum was low in initial fermentation period, but increased during the late fermentation period.
