摘要:

采用顶空固相微萃取-气相色谱-质谱联用技术分析南极磷虾头胸部、腹部和整虾的挥发性风味成分,结合感觉阈值,利用相对气味活度法评价挥发性风味成分对总体风味的影响程度。结果表明,南极磷虾头胸部的主体风味成分为(E,Z)-2,6-壬二烯醛、3-甲基丁醛、3-甲硫基丙醛、壬醛、苯乙醛、D-柠檬烯、(Z)-4-庚烯醛、二甲基硫醚、辛醛、苯甲醛;南极磷虾腹部主体风味成分为二甲基三硫醚、癸醛、壬醛、3-甲基丁醛、辛醛、二甲基硫醚、D-柠檬烯、(Z)-4-庚烯醛;整虾的主体风味成分则包括二甲基三硫醚、癸醛、(E,Z)-2,6-壬二烯醛、3-甲基丁醛、壬醛、3-甲硫基丙醛、辛醛等物质。

Abstract:

The volatile flavor compounds in the cephalothorax, abdomen and whole body of Antarctic krill were
extracted and identified by headspace solid-phase microextraction-gas chromatography-mass spectrometry. The
contributions of volatile compounds to global odor perception were evaluated by a relative odor activity value (ROAV)
combined with odor threshold. The results indicated that (E,Z)-2,6-nonadienal, 3-(methylthio)-propanal, 3-methyl
butanal, nonanal, phenylacetaldehyde, D-limonene, (Z)-4-heptenal, dimethyl sulfide, octanal and benzaldehyde were
the key compounds in the cephalothorax of Antarctic krill, whereas the key flavor compounds in the abdomen were dimethyl
trisulfide, decanal, nonanal, 3-methyl butanal, octanal, dimethyl sulfide, D-limonene and (Z)-4-heptenal. Dimethyl trisulfide,
decanal, (E,Z)-2,6-nonadienal, 3-methyl butanal, nonanal, 3-(methylthio)-propanal and octanal were found to be the key
compounds in the whole body of Antarctic krill.

Key words: Antarctic krill cephalothorax, abdomen, key odor compounds, gas chromatography-mass spectrometry, relative odor activity value
