The global demand of EVOO grew steadily due to its nutritional properties, leading to new countries entering the market as producers. In this context, it is necessary to guarantee the food safety for high value EVOOs through a scientific control method against frequent adulteration scandals. 1H NMR associated to chemometric analysis is a useful tool in order to certify the reliability of a declared geographical origin. The concept behind this scientific approach is not to have an absolute answer in a single global database but to provide a specific product origin certificate. This food fingerprinting system has enabled the creation of a tailor-made database. Our activity is focused on the implementation of this 1H NMR profiling database. The quality confirmation of validated oils is also given by the basic analysis of both industrial, and non-industrial oils obtained through the micromolishing process. The research is expanded from the Italian and in particular Apulian  and Tuscan  EVOOs to the organic community and non-community ones. This allows us to recognize the presence of olive oils coming from different areas, as well as their relating features. The method evaluates shares of different oils inside a blend. Thus, the 1H NMR-based metabolomics profiles collection represents a powerful instrument for assessing EVOOs origin and authenticity in the world production.
