固相微萃取-气质联用分析方法评价 水产品鲜度研究进展

鲜度是影响水产品品质的重要因素。鲜度评价对水产品加工、储运及安全都具有重要意义。固相微萃取-气质联用方法是一种快速方便检测食品挥发性物质的方法。此方法已经被应用于一些水产品如鳕鱼、鲅鱼、金枪鱼、鲈鱼等挥发性物质检测及鲜度评价中。该方法具有客观、快速、方便的特点。本文就目前该分析方法在水产品鲜度评价中的原理、应用及前景作一简要综述。

Research progress of evaluation of seafood freshness by solid phase microextraction and gas chromatography/mass spectrometry

Freshness makes a great contribution to the quality of fish. Freshness evaluation is essential for the processing, storage and transportation, and safety of fishery products. Solid phase microextraction and gas chromatography/mass spectrometry method is a convenient and rapid method to detect volatile compounds in foods. This method has been used in determination of volatile compounds in seafood such as cod, mackerel, tuna and seabass and evaluation of freshness as well. It is a kind of objective, rapid and convenient method. In this paper, the principle, application, and prospect of this technique were reviewed.
