| 摘 要： | 以我国重要食用的淡水鱼之一,白鲢鱼为原料,采用涂有聚二甲基硅氧烷-二乙烯苯(PDMS-DVB)涂层的固相微萃取头萃取挥发性成分,以鱼肉气味成分中含量比较多的物质(己醛、己醇、庚醛、庚醇、辛醛、1-辛烯-3-醇、壬醛等)为参照对象,比较了不同涂层的萃取头、萃取时间、萃取温度、离子强度、初始状态下不分流时间的长短、解吸时间、程序升温速率等因素对固相微萃取的萃取效率以及气相色谱-质谱联用仪分析效率的影响,建立了顶空固相微萃取技术与气相色谱-质谱联用仪分析鉴定鱼肉中的气味成分的方法。结果表明:固相微萃取技术有效地吸附了鱼肉中的挥发性成分,经NIST质谱数据库检索和文献对照,共确定27种成分,并且萃取时不会造成环境污染,分析简单、快速、经济。

| Abstract: | In this paper, a method for the determination of odors from silver carp using headspace solid phase microextraction (HS SPME) and gas chromatography mass spectrometry (GC/MS) was presented. The SPME fiber was coated with polydimesiloxane divinylbenzene (PDMS DVB). The extraction and chromatography conditions were optimized with compared some common analysis in fish meat volatiles. The volatiles were hexanal,1 hexanol, heptanal, heptanol, octanel, 1 octen 3 ol and nonanal. The results showed that SPME was effective to analysis of the volatiles in fish meat. |
