The brine Korea cabbage (BKC) with various ingredients was stored at 5$^{\circ}C$ and 15$^{\circ}C$ for 13 days to examine the changes in pH, total acidity, ascorbic, and cholrophylls. Decrease in pH and increase in total acidity in the BKC stored at 15$^{\circ}C$ were greater than in the BKC stored at 5$^{\circ}C$, indicating these changes are closely related to the storage temperature. The effect of ingredints was various; garlic, red pepper powder, and fermented anchovy juice accelerated the decrease in pH and increase in total acidity; mustard powder and leaf mustard suppressed their changes and freen onion and ginger had no effect. At both temperatures, ascorbic acid was remained at high level in the BKC with leaf mustard, but it was maintained at lowest level in the BKC with ferented anchovy juice. Degradation od chlorophylls was slow in the BKC with leaf mustard, which maintained the high level os ascorbic acid during storage. Meanwhilr the degradation of chlorophylls or production of pheophytin and pheophorbide was cinsistent with the production of acid. These results suggset that degradation of chlorophylls in a BKC was positively correlated with ascorbic acid content and the acid produced during storage.
