Abstract: In this study, the aroma components of bead-shaped green teas were compared through headspace solid-phase microextraction (HS-SPME) and gas chromatog.-mass spectrometry/olfactometry (GC-MS/O) coupled with chemometrics. A total of 62 volatile compounds were identified in 16 green tea samples. Notably, comparison of GC-MS/O and odor activity values (OAV) results revealed that nonanal, decanal, (E)-2-nonenal, β-ionone, and 1-octen-3-one were the most powerful aroma-active compounds that contributed to the aroma profile of the bead-shaped green teas. Furthermore, multivariate statistical techniques (such as principal component anal., partial least squares-discriminant anal., and hierarchical cluster anal.) were used to characterize the bead-shaped green teas according to their geog. origin and the flavor characteristics of their volatile compounds Addnl., the variable importance in the projection method was used to identify 20 volatile markers that could successfully distinguish bead-shaped green teas on the basis of three flavor characteristics. The results of the anal. revealed that HS-SPME and GC-MS/O coupled with chemometrics can provide an effective method for characterizing and classifying bead-shaped green teas.Methyl Salicylate(cas: 119-36-8COA of Formula: C8H8O3) was used in this study.
Methyl Salicylate(cas: 119-36-8) has been used: as a component of clarifying solution for treating Mongolian gerbil cochlea intact for immunofluorescence analysis, as a plant elicitor to test its effect on reducing the whitefly population from tomato plants.COA of Formula: C8H8O3
