“…For example, capillary zone electrophoresis (Horie & Kohata, ; Wang, Su, Liang, & Sun, ), ultraperformance liquid chromatography (Moradi, Kiarostami, & Amini, ; Park, Kim, & Shin, ), gas chromatography‐mass spectrometry (Ma et al., ; Yang et al., ), electronic nose (e‐nose), and so on (Banerjee, Chattopadhyay, Tudu, Bhattacharyya, & Bandyopadhyay, ; Wang et al., ; Zhu, Chen, Wang, Niu, & Xiao, ) are widely used in tea quality assessment. Owing to the rapid development of instrumental techniques, component analysis for aroma differences among various teas are becoming less time consuming and laborious (Choudhury, Yabansu, Kalidindi, & Dennstedt, ; Cliff, Law, Luecker, Scaman, & Kermode, ; Marguí & Voutchkov, ). Additionally, as an effective analytical tool, multivariate statistical methods, such as linear discriminant analysis (LDA), principal component analysis (PCA), hierarchical clustering analysis, and partial least squares discriminate analysis, are also combined with the instrument to obtain useful information and simplify the results (Galinsky et al., ; Granato et al., ; Monakhova, Godelmann, Kuballa, Mushtakova, & Rutledge, ).…”
