The effect of glutinous rice paste on the physicochemical, microbiological, and sensory characteristics of Puchukimchi during fermentation was investigated. Puchukimchi is a kind of korean kimchi made with Leek (Allium odorum L.). Puchukimchi made with various concentrations (0.0, 0.5, 1.0, 2.0, 3.0%) of glutinous rice paste were fermentated at 10$^{\circ}C$ up to 45 days. As a fermentation progressed, pH decreased in all of the treatments, while total acidity increased. By increasing the concentrtion of glutinous rice paste added, an increase of total acidity was noted from Puchukimchi. The reducing sugar content in most samples was decreased during fermentation, however, 1.0% treatment showed a relatively slow decrease. The total vitamin C content increased sharply at the 2nd-day of fermentation and then, gradually decreased especially from the 8th-day following a sigmoidal changing pattern. The total vitamin C content was the highest in Puchukimchi made with 1.0% glutinous rice paste. The counts of lactic acid bacteria increased remarkably and then decreased gradually after optimum ripening period, i.e., the palatable period of Puchukimchi during fermentation.
