Edible Parts

Key odor compounds in different edible parts (abdomen, claw, leg meat and gonad) of steamed female Chinese mitten crab (Eriocheir sinensis) were extracted by a new type of adsorbent (MonoTrap), identified by gas chromatography-mass spectrometry (GC-MS) and determined by gas chromatography-olfactometry (GC-O). Ninteen key odor compounds (odor intensity value≥3) were obtained in Chinese mitten crab, among which trimethylamine (fishy), (Z)-4-heptenal (fishy) and 2-ethylpyridine (roasted potato) were found in all four edible parts of Eriocheir sinensis. In addition, 8 KOCs (2-ethylfuran, benzaldehyde, 1-octen-3-ol, 6-methyl-2-heptanone, 2-pentylfuran, (E,E)-3,5-octadien-2-one, nonanal and decanal) were also identified in the abdomen meat, 5 KOCs (toluene, 2,5-dimethylpyrazine, 1-octen-3-ol, (E,E)-3,5-octadien-2-one and 2-methylnaphthalene) in the claw meat, 3 KOCs (toluene, 2-nonanone and nonanal) in the leg meat, and 12 KOCs (1-penten-3-ol, toluene, hexanal, 1,3,5-octatriene, benzaldehyde, 1-octen-3-ol, 6-methyl-2-heptanone, 2-pentylfuran, (E,E)-3,5-octadien-2-one, nonanal, (E,Z)-2,6-nonadienal and decanal) in the gonad part.
