Volatile metabolomics highlights tea trichome's positive contribution to aroma and quality of white tea.

ABSTRACT: Tea trichomes, rich in secondary metabolites, are hypothesized to significantly influence white tea aroma, yet their biochemical contributions remain unclear. This study investigated the volatile profiles of tea trichome and tea body across six white tea samples using headspace solid-phase microextraction combined with gas chromatography-mass spectrometry (HS-SPME-GC-MS) and multivariate statistical analysis. Comparative analysis revealed significant differences in the volatile profile between tea trichome and tea body in all tested samples, with major differences lying in the content of volatile components. Sixteen potential key aroma components with relative odor activity value (ROAV) ≥ 1 and 39 aroma modifiers (0.1
