Abstract


Identification of volatile flavour compounds of hoki (Macruronus novaezelandiae) and orange roughy (Hoplostethus atlanticus) oils has been carried out.  Flavour compounds were extracted by a purging system and collected using a porous polymer Tenax TA trap.  The gas chromatography-mass spectrometry (GC-MS) was used to identify the volatile flavour compounds.  The predominant compounds contributing to the volatile flavour of hoki oil were methyl ethyl benzoate, ethyl benzoate and 1,1-dimethylethyl-2-propionic acid.  Meanwhile, the main volatile flavour components of orange roughy oil were toluene, cyclohexane, 1,1-dimethylethyl-2-methyl propionic acid and tetrachloroethane.
