Abstract

The main goal of this study is to rapidly screen olive oil contents by acquiring one dimensional (1D) 1H NMR spectra of 38 samples from Turkey, The Middle East, and Libya. The quantitative analysis of the 1H NMR helped in distinguishing the geographical origin of the olive oil samples. The intensity of 1H NMR variables was submitted to the statistical method, analysis of variance (ANOVA). As a result of combining the NMR data and ANOVA, olive oils were discriminated based on regional origin rather than province. This less time consuming discriminative screening by 1H NMR does not require any further analysis of the olive oil, including oxidative stability measurements or gas chromatography. The possibility of determining authenticity, even in an olive growing area of a small village was also shown. The two-dimensional (2D) non-invasive 1H DOSY NMR experiment, known as "NMR chromatography", was used to determine the olive oil sub-fraction. Copyright: © 2014 CSIC.
