Abstract

This study was conducted to determine the potential use for salted Kimchi cabbage and kimchi paste by analyzing the quality characteristic of kimchi prepared with stored them. Salted Kimchi cabbages were packed with the 2% brine and kimchi paste were stored at $4^{\circ}C$ for 8 weeks, respectively. Kimchi prepared at 0 day and kimchi prepared with stored salted Kimchi cabbage and kimchi paste every week were stored at $4^{\circ}C$ for 8 weeks. The salinity and titratable acidity of salted Kimchi cabbage packed with the brine was lower than control. The results of salinity, pH and moisture contents of kimchi paste did not show any significant differences during storage, however, the titratable acidity was increased. In sensory evaluation, salted Kimchi cabbage packed with the brine showed higher score in overall preference than control. Kimchi paste showed 4.9~6.1 score in overall preference during storage. The titratable acidity of kimchi prepared with stored salted Kimchi cabbage and kimchi paste was lower than control. But, the results of sensory evaluation did not show significant difference among treatments. The study suggested that the use of 2% brine is an effective way for extending shelf-life of salted Kimchi cabbage and Kimchi prepared with stored salted Kimchi cabbage and kimchi paste every week is effective to delay the fermentation but no difference in sensory evaluation.
