固相微萃取在食品香味分析中的应用

Applicantion of Solid-phase Microextraction in Food Flavor Analysis

固相微萃取是近年来才发展的复杂样品分析前预处理技术,它的敏感、快速、样品用量少、操作简单、不用溶剂、可自动化、能直接与气相色谱等现代仪器联用的特点使其在食品香成分分析上具有强大的优势。本文介绍了固相微萃取技术,综述了近十年有关该技术在食品香成分分析上的应用,并对其用于食品香味分析的未来发展进行了展望。

Solid phase microextraction (SPME) is a recent sampling technique bearing such advantages as simple, fast, solvent-free and inexpensive to carry out. Moreover SPME has been interfaced to GC and other analytical instruments and possesses agood potential for method automation. SPME provides a complementary or even superior alterative method for the preconcentrationof flavor components from food matrix. In this paper, the technical characteristics of SPME was introduced, its applicationspecially in food flavor analysis was reviewed and further prospected.
