Abstract

Xanthan gum (XG) was investigated for use as a thickening and stabilizing agent in kimchi during fermentation at 10$\^{C}$. The mixing ratios of XG to salted Chinese cabbage were 0.1, 0.3 and 0.5%. Quality characteristics of kimchi such as pH, titratable acidity, reducing sugar content and microbial loads were measured. pH and reducing sugar content showed abrupt decreases after 5 day lag time until 20 days, while titratable acidity steadily increased during fermentation. The addition with 0.5% XG retarded the change rates of pH and titratable acidity showing the slowest change. Kimchi samples added with 0.1% and 0.3% XG maintained a higher reducing sugar content during the whole fermentation period of 30 days. Microbial loads showed an abrupt increase from 5 to 10 days, and maintained a nearly same load thereafter. Kimchi sample added with 0.3% XG showed better scores in color, aroma and taste.
