    Article Title: Development and comprehensive SBSE-GC/Q-TOF-MS analysis optimization, comparison, and evaluation of different mulberry varieties volatile flavor.
    Article Snippet: Optimization of seven parameters of stir bar sorptive extraction (SBSE) on mulberry volatile components for the first time.. A total of 347 volatile components were identified and quantified in 14 mulberry varieties, predominantly encompassing esters, aldehydes, terpenoids, hydrocarbons, ketones, alcohols, heterocyclics, acids, and phenols.. Hexanal and (E)-2-hexenal were the dominant volatiles.

    Article Title: Insight into volatile metabolites and key odorants in black teas processed from Jianghua Kucha tea germplasm (Camellia sinensis var. assamica cv. Jianghua).
    Article Snippet: Jianghua Kucha (JHKC) is an ancient tea germplasm, which presents a high value for resource utilization but was less developed in aroma research.. In this study, volatile metabolites in fresh leaves and corresponding black teas of JHKC, along with odorants of JHKC black teas were systematically investigated using stir-bar sorptive extraction in combination with gas chromatography–mass spectrometry (GC–MS) and GC–olfactometry/MS (GC–O/MS) technologies.. A total of 128 and 135 volatile compounds were identified in fresh leaves and black teas, respectively, along with 13 key differential volatile components derived from fatty acids, pigments, glycoside precursors, and the terpene pathway.

    Article Title: Uncovering characteristic and enantiomeric distribution of volatile components in Huangshan Maofeng and Zhejiang baked green teas
    Article Snippet: Huangshan Maofeng (HSMF) is a famous baked green tea from the Anhui Province of China, known for its “clean and fresh” flavor.. Zhejiang, another major tea-producing province, focuses on the production of green teas.. This study aimed to analyze the characteristic aroma components and specific enantiomeric distribution of significant chiral volatile compounds in HSMF and Zhejiang baked green tea (ZJ-BGT) with respect to their origins, cultivars and grades using stir bar sorptive extraction combined with non-targeted gas chromatography-mass spectrometry (GC-MS) and enantiomeric GC-MS approaches.
