P02: COMPREHENSIVE ANALYSIS OF FATTY ACIDS IN OYSTERS BY GC-FID/GC-MS

摘要

To the analysis of fatty acids in marine biota are generally related some uncertainties. One problem is that most profile analyses reported in literature disagree about the number and type of fatty acids monitored as well as about the percentage to assign to their sum over total fatty acids. Another issue is the discriminant effect in the split/splitless injector of gas chromatographs which can lead to relevant errors in quantifying DHA (22:6 ω3). In a previous work we solved these troubles for 12 fish species. In the present one the case of bivalve mollusks (oysters, mussels) is dealt with. Oysters are part of the analytical activity for producing a new Reference Material within the H2020 Project "PRO-METROFOOD".
