中文摘要：研究咸带鱼加工过程中挥发性风味成分的变化情况。采用固相微萃取-气相色谱-质谱联用法分别检测鲜鱼、腌制、浸泡脱盐、干燥、成品5个加工阶段的挥发性风味成分,经NIST 05a.L谱库数据库检索,确定其风味成分。结果表明:鲜鱼、腌制、浸泡脱盐、干燥、成品这5个阶段挥发性风味成分种类数分别为49、72、7 0、7 5种以及7 2种。其中,成品咸鱼中己醛、庚醛、辛醛、壬醛、1-戊烯-3醇、1-戊醇、己醇以及1-辛烯-3醇含量较高,相对含量分别为28.26%、8.64%、6.54%、4.37%、7.34%、3.55%、4.18%和4.72%。腌制和干燥是风味产生的主要加工阶段。醛类、醇类、酮类和烃类是主要的挥发性物质的种类,其中己醛、庚醛、辛醛、壬醛、1-戊烯-3醇、1-戊醇、己醇以及1-辛烯-3醇是咸带鱼风味的主要成分。

外文摘要：In order to know the mechanism of flavor formation and the pathway of salination during salted hairtail processing from fresh hairtail through salting,soaking to desalt and two-stage drying,the changes of main volatile flavor compounds were analyzed.The volatile composition of fresh,salted,desalted,first dried and second dried samples was analyzed by solid phase micro-extraction（SPME） coupled to gas chromatography-mass spectrometry（GC-MS） and NIST 05a.L MS spectral library searching and alignment.A total of 49,72,70,75 and 72 compounds were identified in fresh,salted,desalted,first dried and second dried samples of hairtail,respectively.Hexanal,heptanal,octanal,nonanal,1-penten-3-ol,1-pentanol,hexanol and 1-octen-3-ol showed a higher level in second dried second dried（final product） with a relative content of 28.26%,8.64%,6.54%,4.37%,7.34%,3.55%,4.18% and 4.72%,respectively.The compounds responsible for the flavor of salted hairtail were mostly formed during salting and drying,consisting mainly of aldehydes,alcohols,ketones and alkanes,including hexanal,heptanal,octanal,nonanal,1-penten-3-ol,1-pentanol,hexanol and 1-octen-3-ol.
