2, 4-Decadienal was autoxidized by subjecting a purified sample to an atmosphere of pure oxygen for 14 hours. A qualitative analysis of the autoxidative degradation products was made utilizing tandem gas chromatography and mass spectrometry. Additional information was obtained from the determination of the melting point of the DNP-hydrazone derivative...
A rapid gas liquid chromatographic method was adapted to processed
Dungeness crab for the determination of basic and neutral
volatiles. Methylamine, dimethylamine, and trimethylamine were
measured in processed Dungeness crab for the first time. Generally,
the range for trimethylamine was 42 ppm for frozen crab to 700 ppm
for iced...
