This study was conducted to investigate and make comparison between treatment which was reduced the reducing sugar content from Chinese cabbage using salting and desalting processes prior to Kimchi fermentation , and control for the effect of reducing sugar content on Kimchi fermentation at $25^{circ}C$. In the early stage of Kimchi fermentation , the amount of reducing sugar (5.7mg/ml) in treatment was much smaller than that (15.1mg/ml) in control. Reducing sugar content of treatment decreased drastically during the first two days and then levelled off . Whereas, that of control dropped significantly up to the first four days of fermentation. pHs of treatment and control decreased significantly during the first two days and then showed gentle slopes. Acidities of treatment and control were increased continuously during the entire range of fermentation . The acidity of control reached to 0.75% in 3 days of fermentation, while that of treatment was shown after 6 days. Hardnesses of treatment and control using a puncture test were almost constant and the hardness value of treatment was higher than that of control during whole fermentation period. The total bacteria and lactic acid bacteria counts increased drastically during the first day of fermentation and the increase of total bacteria counts was mainly caused by that of lactic acid bacteria counts.
