Investigation of Volatile Compounds in Varied Types of Gardenia White Teas Utilizing HS-SPME-GC-MS and Multivariate Analysis.

ABSTRACT: Gardenia tea is esteemed for its delicate and fragrant aroma. Background: However, there is a scarcity of studies focused on the aromatic properties of gardenia-scented white tea, particularly regarding how these aroma profiles evolve over different storage durations. Methods: This research sought to analyze the volatile compounds present in gardenia white tea through headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC-MS) alongside multivariate analysis techniques. Results: Findings indicated that the main chemical categories found in newly white tea (NWT), aged white tea (AWT), gardenia newly white tea (GNWT), and gardenia aged white tea (GAWT) included esters, terpenoids and ketones. The multivariate analysis pinpointed 11 signific
