Abstract Olive oil is an essential daily commercial product in people's lives, attributing its popularity to its rich taste and high nutritional value, making it one of the vital elements of the Mediterranean diet. Olive oil's impact extends to consumer health and the industry's economic landscape. This research focuses on the application of optical methods, in particular fluorescence spectroscopy, to verify the authenticity and safety of olive oil. The main objective is the comprehensive detection of seed and mineral oils in olive oil. The study includes the analysis of 23 samples of pure olive oil, 260 samples of adulterated olive oil with seed and pomace oil, and 144 contaminated olive oil samples with ten different mineral oils from three companies. These samples were analyzed by fluorescence spectroscopy, and the results were processed by multivariate analysis techniques such as Partial Least Squares (PLS) and Partial Least Squares Discriminant Analysis (PLS-DA). A consequence of this research is the successful prediction of adulteration rate and the detection of contaminants in olive oil. This research was conducted in the Photonics for AgroFood and Environment Laboratory at the Institute of Electronic Structure and Lasers of the Foundation for Research and Technology, Hellas.
