Abstract: The production area of the Protected Denomination of Origin (P.D.O.) Siurana olive oils can be divided into two regions: Montsant and Camp de Tarragona, with different orography, soil characteristics and climatic conditions. As a result of these differences, the oils have variable stability. Here we show that excitation-emission fluorescence can detect these variations. Oils from the Montsant region (more stable) show more fluorescence intensity above 500 nm (due to vitamin E) and less below 500 nm (due to oxidation products) than those from the Camp de Tarragona region. Discrimination between oils from the two P.D.O. Siurana regions was achieved by means of discriminant unfold partial least squares regression, giving a percentage of correct classification of 94% for Siurana-Camp and 100% for Siurana-Montsant oils.
