- Abstract:
- An analytical method was developed to measure δ13C, and for the first time, δ2H of fatty acid methyl esters (FAMEs) extracted from olive oil triglycerides, after base-catalysed transesterification with methanol. FAMEs are analysed using Gas Chromatography Combustion/Pyrolysis Isotope Ratio Mass Spectrometry (GCC/Py-IRMS). Accuracy, precision and uncertainty of the whole method (from preparation to measurement) were determined as well as the impact of methylation on δ13C and δ2H. The obtained performance of the method is satisfying and allow the determination of reliable data.
