摘要：

Gas chromatography/mass spectrometry (GC/MS) analyses indicated that volatile fractions of channel catfish (Ictalurus punctatus) covering a range of flavor quality were all found to contain 2-methylenebornane and 2-methyl-2-bornene, dehydration products of 2-methylisoborneol. Gas chromatographic effluent sniffing indicated that the only ''earthy/musty'' odor compounds present were identified as 2-methylisoborneol and geosmin. It was concluded that 2-methylenebornane and 2-methyl-2-bornene, which do not have discernible odors, do not contribute to off-flavor, contrary to an earlier study.
