The volatile compounds of cooked meat in farmed obscure puffer (Takifugu obscurus) were isolated by simultaneous distillation and extraction (SDE)and headspace solid phase micro extraction (HS-SPME), and analyzed with gas chromatography-mass spectrometry (GC-MS). A total of 91 volatile compounds were identified under 3 different conditions by GC-MS analysis including 32 aldehydes, 11 alcohols, 10 ketones, 21 N- or S-containing aromatic compounds, 13 alkanes, 3 esters, and 1acid. In order to evaluate the major potential impact odorants extracted by SDE, the odor activity value (OAV) was calculated together with GC-MS. To estimate the contributions of volatile compounds to flavor isolated by SDE and HS-SPME, a parameter named relative odor activity value (ROAV) was applied. Results obtained showed that on the basis of OAV, it indicated that the compounds potentially most important to obscure puffer included 2,6-nonadienal, trimethylamine, 2,3-butanedione, (Z)-4-heptenal, 2-nonenal, and 3-methylbutanal. Based on ROAV, it was found that 2,6-nonadienal, trimethylamine, (Z)-4-heptenal, 2,3-butanedione, 2-nonenal, 3-methylbutanal, benzaldehyde, 2-ethylfuran, ethyl acetate, (E,E)-2,4-octadienal, octanal, 1-octen-3-ol, and nonanal may be responsible for the special flavor of cooked meat in the obscure puffer.
