Sažetak
Olive oil represents an important ingredient in the Mediterranean diet and is appreciated for both nutritional and sensory properties, often related to geographical area where the olives are grown and the olive cultivar. As consumers demand correct labeling of olive oil, there is a need for analytical techniques that are able to provide data and confirm traceability of origin and authenticity of the oil. Stable isotope ratios have long been known to have enormous potential for food source screening and have been used in authenticity studies for many food products. Results of stable isotope ratios analyzed by EA-IRMS technique are not influenced by cultivar or the agricultural techniques in the groves, and is a valuable tool for geographical discrimination of unknown samples. The carbon isotope ratio (13C/12C) of olive oils was determined by EA-IRMS (Elemental Analyzer – Isotope Ratio Mass Spectrometry). All analyses were performed in triplicates. Analysis of variance was performed on the obtained dana using SAS Institute v9.4 software.
