Abstract(s)

Olive oils produced in the Douro’s region (north of Portugal) are greatly appreciated due to their specific chemical-sensory characteristics, which can be associated to the region’s “Terroir”. Thus, for olive oil producers and consumers, the capability to guarantee the authenticity of the geographical origin of these oils is of utmost importance. In this sense, this study aimed to evaluate the possibility of using an electronic nose (E-nose), with nine metal oxide semiconductors (MOS), as a non-invasive analytical tool to recognize the geographical origin of olive oils from two geographical sub-regions: “Côa” and “Douro”
