Oe. Mills et al., DEHYDRATION PRODUCTS OF 2-METHYLISOBORNEOL ARE NOT RESPONSIBLE FOR OFF-FLAVOR IN THE CHANNEL CATFISH, Journal of agricultural and food chemistry, 41(10), 1993, pp. 1690-1692
Gas chromatography/mass spectrometry (GC/MS) analyses indicated that v
olatile fractions of channel catfish (Ictalurus punctatus) covering a
range of flavor quality were all found to contain 2-methylenebornane a
nd 2-methyl-2-bornene, dehydration products of 2-methylisoborneol. Gas
chromatographic effluent sniffing indicated that the only ''earthy/mu
sty'' odor compounds present were identified as 2-methylisoborneol and
geosmin. It was concluded that 2-methylenebornane and 2-methyl-2-born
ene, which do not have discernible odors, do not contribute to off-fla
vor, contrary to an earlier study.
