推荐 为解决传统gc - ms在复杂基质中难以有效分离异构体和微量成分的问题，研究人员以武夷岩茶（水仙）为对象，开展烘焙过程中挥发性成分动态变化研究。采用gc - ims和gc×gc - o - ms结合机器学习，鉴定出多种关键差异化合物，为茶叶加工和质量控制提供理论支持。

本研究针对东方甜瓜香气活性物质鉴定技术不足的问题，采用hs-spme结合gc?×?gc-o-tof-ms和gc-ms技术，结合aeda、香气重组与缺失实验，系统分析long4（果香型）和zhcg（青瓜香型）的挥发性成分差异。研究发现124种挥发性物质中32种具有香气活性，其中8种酯类物质主导long4的果香特征，7种醛醇类物质决定 ...
