Distinguishing Between One-Day-Old Cod ( Gadus morhua ) and Haddock ( Melanogrammus aeglefinus ) Eggs by Gas Chromatography and SIMCA Pattern Recognition

Single cod (Gadus morhua) and haddock (Melanogrammus aeglefinus) eggs were acid hydrolized. All the fatty acids were liberated and converted to methyl ester in a one-step reaction. The nonpolar hexane extract was analyzed by high resolution gas chromatography (HRGC). Selected peaks, occurring in bot...

Description
Summary:Single cod (Gadus morhua) and haddock (Melanogrammus aeglefinus) eggs were acid hydrolized. All the fatty acids were liberated and converted to methyl ester in a one-step reaction. The nonpolar hexane extract was analyzed by high resolution gas chromatography (HRGC). Selected peaks, occurring in both types of samples and in all chromatograms, were used to create a matrix for multivariate analysis. We conclude that cod and haddock eggs can be distinguished using this method.
