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。 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.
