3D front-face fluorescence spectroscopy for characterization of extra virgin olive oil and olive oil according to the spectral pattern CIGR Journal
Lleó, Lourdes; Hernández-Sánchez, Natalia; Ammari, Faten; Roger, Jean-Michel.
3D front-face fluorescence spectroscopy and principal component analysis (PCA) were used to differentiate between Extra Virgin Olive (EVOO) and Olive Oil (OO). The results show that 3D front-face fluorescence could be an effective tool to characterize EVOO and OO. Fourteen samples of olive oils were acquired directly from producers and from retail markets and their 3D fluorescence spectra were measured and analyzed. The first principal component of the PCA model retained the most important variability as a combination of freshness due to the presence of antioxidant compounds and chlorophyll; and of oxidation stage due to the presence of oxidation products. Olive oil samples presented different spectral pattern providing different scores for EVOO and OO in...

Development of a qPCR Method for the Identification and Quantification of Two Closely Related Tuna Species, Bigeye Tuna ( Thunnus obesus ) and Yellowfin Tuna ( Thunnus albacares ), in Canned Tuna ArchiMer
Bojolly, Daline; Doyen, Perine; Le Fur, Bruno; Christaki, Urania; Verrez-bagnis, Veronique; Grard, Thierry.
Bigeye tuna (Thunnus obesus) and yellowfin tuna (Thunnus albacares) are among the most widely used tuna species for canning purposes. Not only substitution but also mixing of tuna species is prohibited by the European regulation for canned tuna products. However, as juveniles of bigeye and yellowfin tunas are very difficult to distinguish, unintentional substitutions may occur during the canning process. In this study, two mitochondrial markers from NADH dehydrogenase subunit 2 and cytochrome c oxidase subunit II genes were used to identify bigeye tuna and yellowfin tuna, respectively, utilizing TaqMan qPCR methodology. Two different qPCR-based methods were developed to quantify the percentage of flesh of each species used for can processing. The first one...
