계저별,발효온도별 총각김치의 품질 특성의 변화 = Seasonal Changes in Quality of Chonggak Kimchi Fermented at Different Temperatures

다국어 초록 (Multilingual Abstract)

In order to establish the basic scientific data on the fermentation characteristics of chonggak kimchi (CGK), we studied with CGKs prepared at different seasons and stored at various temperatures (5~23˚C). Changes in pH and acidity of CGK fermented at different temperatures were typical. However, acidity of summer CGK stored under 15˚C did not reach 1.0% since the amount of reducing sugar in the summer radish was lower by over 1% than the ones from the other seasons. Growths for Leuconostoc and Lactobacillus spp. over 8.0 logCFU/mL were observed in CGKs fermented above 10˚C. Changes in Max G, cutting force, of CJK from different seasons were apparent. Max Gs for spring and summer CGK were decreased immediately right after storage while Max Gs for winter CGKs were increased slowly during storage. According to the results of sensory evaluation, CGKs revealed the highest overall acceptability when acidity of kimchi reached 0.7±0.1% under the given fermentation condition. However, CGK prepared with radish from winter or summer season tasted better than the one made in the spring. But the edible periods for winter CGKs were longer, compared with summer CGKs fermented at the same temperature. In conclusion, CGK fermented at 10˚C in the winter season gives a better taste with longer edible duration than the other CGKs.
