|
The aroma components of Korean green tea in the south western part of Mt. Chiri prepared by the traditional method from native variety were analyzed using GC and GC-MS. The patterns on GC chromatograms of the three samples from the flushes plucked in early spring were similar, though they are prepared by different producers in the area of Hadong-kun, Kyung sang nam-do. A total of 51 aroma compounds were identified in all samples. Main component in the aroma compounds of these teas were geraniol, benzyl alcohol, 2-phenylethanol, β-ionone, benzyl cyanide and linalool oxides. The aroma components of green teas manufactured by the different plucking periods were also compared. The amounts of geraniol, typical rose floral aroma were particularly decreased in the final plucking period. The amounts of pyrazines and furfuryl alcohol, typical roasted aroma and nutty aroma were slightly increased in later plucking period.
