초록

The objective of this study was to determine the quality characteristics of cabbage juice fermented by lactic acid bacteria from Kimchi (Leuconostoc mesenteroides, Lactobacillus sakei SL1103, Lactobacillus plantarum LS5, and mixed starter). Cabbage juice was inoculated with lactic acid bacteria and fermented at 30 for 72 hrs. Changes in lactic acid bacteria number, pH, titratable acidity, Brix, and color during fermentation were analyzed. After fermentation for 24 hrs, cabbage juice fermented by mixed starter showed the highest number of lactic acid bacteria (9.45 log CFU/mL). The pH of all cabbage juice also decreased to 3.88~4.19 sharply, while cabbage juice fermented by Lac. sakei SL1103 showed the highest Brix ($8.38^{\circ}Bx$). Cabbage juice fermented by mixed starter showed the highest L value (56.83). In the sensory evaluation, cabbage juice fermented by a mixed starter (Leu. mesenteroides, Lac. sakei SL1103, and Lac. plantarum LS5) showed the highest preferences in taste, flavor, and overall acceptability. Therefore, cabbage juice fermented by mixed starter (Leu. mesenteroides, Lac. sakei SL1103 and Lac. plantarum LS5) has the highest potential for the development of fermented cabbage juice as an excellent bioactive functional food.
