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

)-2,4-decadienal and benzeneacetaldehyde, which were shared by all samples in tea trichome and tea body. Notably, most of these key and modified aroma components showed higher relative contents and ROAVs in tea trichome than those in tea body. These data reveals that tea trichome positively enhance white tea's aroma quality, notably intensifying fruity, floral, sweet, green, and woody notes. This study systematically clarifies the biochemical specificity of tea trichome and their positive impact on white tea aroma, highlighting their critical role in aroma formation through differential accumulation of aroma contributors.
