Abstract: The calorimetric method described here investigates the solid-liquid phase transitions in a Tuscan extra-virgin olive oil in order to evaluate the changes induced by light exposition. The parameters of the freezing and the melting curves show high sensitivity to oil quality degradation, in agreement with the data from routine tests at disposal. Possible applications of the method are discussed.
