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、70、75种以及72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。

Abstract: 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.

Key words: salted hairtail (Trichiurus haumela), solid phase micro-extraction(SPME), gas chromatography-mass spectrometry (GC-MS), volatiles flavor compounds
