烟用香精挥发性成分的SHS与SPME采样分析比较

Comparison between SHS and SPME Sampling for Volatile Components in Tobacco Flavor

  • 摘要: 分别采用静态顶空仪和固相微萃取两种方法对香精中的挥发性成分进行顶空取样,用气相色谱/质谱法进行了定性分析,并对这两种方法鉴定出的化学成分、重复性和灵敏度等进行了比较。结果表明:两种方法测定出的挥发性成分大多为烯烃类、酯类和醇类等,且都具有较高的灵敏度及良好的重复性以及快速、简便、不使用溶剂和样品非破坏性等优点,适合于香精的剖析定性。

     

    Abstract: The volatile components in same flavor were sampled with static headspace sampler (SHS) and solid-phase micro-extraction (SPME), respectively, and then identified by GC/MS.The identified components, repeatability and sensitivity of these two sampling methods were compared.The results showed that most of volatile components identified by SHS and SPME were alkenes, esters, alcohols, and etc.These two methods feature high sensitivity, good repeatability, rapidity, convenience, nondestructive sampling and etc.Both of them are suitable for the qualitative analysis of flavor.
