响应面法优化固相微萃取-气质联用法检测鸭肉中挥发性风味物质

为优化鸭肉中挥发性风味物质的萃取条件，在单因素试验基础上，根据Box-Behnken 试验设计原理，以鸭肉挥发性风味物质的色谱图总峰面积为响应值进行响应面分析。结果表明，最佳萃取条件为鸭肉萃取量为2.4g、萃取时间42min、萃取温度49℃。在此条件下检测到鸭肉中含有烯烃类、醛类、酮类、含氮含硫含氧类及杂环化合物等挥发性风味物质27 种。

Optimization of SPME-GC-MS Conditions for Flvour Compounds Determinationin in Duck Meat by Response Surface Analysis

To lay a foundation for the accurate determination of the flour compounds in duck leg meat by solid-phase microextraction (SPME) and gas chromatography coupled with mass spectrometry (GC-MS), the optimization of the SPME conditions affecting the total ion current chromatographic peak area of duck meat extract was investigated using single factor and response surface methodology based on Box-Behnken central design. The optimal extraction conditions were obtained as follows: sample load 2.4 g and extraction temperature 49 ℃ for an extraction duration of 42 min. Totally 27 volatile flavor compounds were identified in duck meat. They were aldehydes, ketones and N-, S-, O containing and heterocyclic compounds.
