Abstract
A method involving overnight stir bar sorptive extraction (SBSE) headspace gas chromatography/mass spectrometry (GC/MS) in negative ion chemical ionization (NICI) mode was developed to determine the presence of aldehydes (cis-4-heptenal, trans,trans-2,4-heptadienal, trans-2-octenal, cis-6-nonenal, trans-2-cis-6-nonadienal, trans-2-nonenal, and trans,trans-2,4-decadienal) in fresh and aged commercial fish oil (untreated and treated with antioxidant blends). Aldehyde standards were quantifiable to >100ppb levels using this method. Only trans,trans-2,4-heptadienal was shown to be present in the commercial fish oil and its presence was used to compare the performance of the two different antioxidant treatments in the fish oil. Includes Powerpoint.
