The effects of wasabi stalk on the taste and storage characteristics of baechukimchi were assessed in the final product. Wasabi stalk was added in different ratios: 0, 1, 3, 5, or 7%(w/v) of Chinese cabbage. As the fermentation progressed, the pH of the product dropped. Total acidity increased in all treatments during fermentation. The total vitamin C content increased during the first 8 to 13 days of fermentation. Reducing sugar decreased in all treatment as fermentation continued. The numbers of total cells and lactic acid bacteria increased until they peaked, and then began decreasing as fermentation continued. With regard to acceptability characteristics, the 3% treatment was most favored. With simple regard to the quantitative level of wasabi stalk addition, the 3% treatment was most appropriate under all testing conditions. In conclusion, stalk seems to be an economical and natural additive which has effects on extension of the shelf life of baechukimchi.
