초록

This principal objective of this study was to evaluate the sensory properties and flavor compounds of Kimchi prepared with different levels (0.0%, 0.4%, 0.8%, and 1.2%) of Backryeoncho extracts (BE). At high levels of BE, Kimchi showed increased level of crispness and flavor, and also jeotgal odor decreased in the sensory evaluation. Addition of 0.8 % BE resulted in the highest scores for color, taste, and overall acceptance of Kimchi. Therefore, addition of 0.8 % BE appears to be an acceptable approach to enhance the quality of Kimchi without reducing acceptability. As a result of flavor compound analysis, a total of 24 volatile flavor compound, including 11 S-containing compounds, 6 terpenes, 1 acid, 1 ester, 1 alcohol, 2 miscellaneous compounds, 2 thiocyanates, etc., were detected by GC/MS. The major volatile compounds were s-containing compounds and terpene hydrocarbon, and especially terpene of sabinene was newly detected in Kimchi with added BE. Levels of 2-vinyl-[4H]-1,3-dithin derived from garlic flavor as a sulfide-containing compound along with diallyl trisulfide derived from green onion flavor were reduced in Kimchi with added 0.8% BE. Most sulfide-containing compounds were reduced in Kimchi with added BE, whereas most terpenes detected in control Kimchi were not detected.
