固相微萃取及其在水产品风味分析中的应用

Solid-phase microextraction and its applications in flavor analysis of aquatic products

固相微萃取(SPME)是一种无溶剂萃取技术,它克服了传统样品前处理技术的缺陷,集采样、萃取、浓缩、进样于一体,具有简单、快速、高效、能直接与其他分析仪器联用等优点,已被广泛应用于风味成分的研究。水产品因其独特的风味深受人们的喜爱,研究水产品风味对于评价水产品的新鲜度、生产加工及品质控制等方面具有重要意义。文中主要介绍了固相微萃取技术及其发展,综述了该技术在水产品风味分析中的研究现状,并对SPME在水产品中的应用前景进行了展望。

Solid-phase microextraction （SPME） is an innovation of solvent free sample preparation technology which successfully overcomes traditional sample preparation methods by integrating sample handling operations such as extraction, pre-concentration, and instrumental analysis into a single step. It has been widely used to analyze flavor components due to its simple, inexpensive, solvent-free, time-efficient, portable and easy-to-automate properties. A- quatic products are popular among customers because of its special aroma. Study on volatile flavor compounds of a- quatic products is to provide some reference on freshness evaluation, processing and quality control. This review de- scribes the solid-phase microextraction technique and its development. It summarizes the current research in aquatic products. Meanwhile, the promising prospect of SPME for future application in aquatic products is also discussed.
