“…Aroma is a crucial quality characteristic of Pu-erh tea and extensive research has been conducted to explore its aromatic profile. Various methods such as sensory evaluations, solid-phase microextraction (SPME) ( Chen et al, 2017 ; Lv et al, 2012 ; Wang, Li, et al, 2022 ; Wang, Su, et al, 2022 ), solvent-assisted flavor evaporation (SAFE) ( Zhu, Niu, & Xiao, 2022 ), stir bar sorptive extraction (SBSE) ( Wang et al, 2020 ), gas chromatography–mass spectrometry (GC–MS) ( Feng et al, 2019 , Rong et al, 2023 , Shi, Zhu, Zhang, Lin and Lv, 2019 ), gas chromatography–olfactometry (GC-O) ( Lv et al, 2012 ), odor activity values (OAV) ( Yang, Song, Wang, & Jing, 2019 ), and other analysis methods have been employed ( Zhai, Zhang, Granvogl, Ho, & Wan, 2022 ). Reportedly, >1000 volatile compounds have been detected in Pu-erh tea ( Wang, Li, et al, 2022 ; Wang, Su, et al, 2022 ).…”
