Zeng, Lin published the artcileComparative Analysis of Volatile Compounds in Tieguanyin with Different Types Based on HS-SPME-GC-MS, Application In Synthesis of 6259-76-3, the main research area is Tieguanyin volatile compound HSSPME GCMS comparative analysis; Tieguanyin; aroma; oolong tea; volatile compounds.
Tieguanyin (TGY) is one kind of oolong tea that is widely appreciated for its aroma and taste. To study the difference of volatile compounds among different types of TGY and other oolong teas, solid-phase microextraction-gas chromatog.-mass spectrometry and chemometrics anal. were conducted in this experiment Based on variable importance in projection > 1 and aroma character impact > 1, the contents of heptanal (1.60-2.79μg/L), (E,E)-2,4-heptadienal (34.15-70.68μg/L), (E)-2-octenal (1.57-2.94μg/L), indole (48.44-122.21μg/L), and (E)-nerolidol (32.64-96.63μg/L) in TGY were higher than in other varieties. With the increase in tea fermentation, the total content of volatile compounds decreased slightly, mainly losing floral compounds Heavily fermented tea contained a higher content of monoterpenoids, whereas low-fermentation tea contained higher contents of sesquiterpenes and indole, which could well distinguish the degree of TGY fermentation Besides, the volatiles anal. of different grades of TGY showed that the special-grade tea contained more aroma compounds, mainly alcs. (28%). (E,E)-2,4-Heptadienal, (E)-2-octenal, benzeneacetaldehyde, and (E)-nerolidol were the key volatile compounds to distinguish different grades of TGY. The results obtained in this study could help enrich the theor. basis of aroma substances in TGY.
