AN 29 - Geographical Analysis of Olive Oil Samples Originating from Eight Countries Using Picarro’s Novel Simultaneous 13C + D CM-CRDS Isotope Analyzer
A clear distinction in dual-isotopic ratio measurements of individual samples indicates the applicability of the new combustion analyzer to geographical origin verification and product authentication.
Olive oil samples were analyzed using the world’s first simultaneous δ13C + δD instrument, the Picarro 13C+D Combustion Module-Cavity Ringdown Spectroscopy (CM-CRDS) Isotope Analyzer. Simultaneous measurements of δ13C and δD of the whole oil have been performed on commercially available olive oils produced in Greece, Spain, Italy, California, Lebanon, Israel, Australia and Turkey. Together, the isotopic ratios produce statistically significant differentiation between olive oils from different locations around the globe.
