Abstract:The objective of this work was focused on identifying and characterizing the thermodegradation reactions of chlorophyll pigments present in the virgin olive oil (VOO) as a function of temperature and the initial composition of pigments in the oily matrix, in order to predict the behaviour of these markers towards the variables thermal regulating the critical points of their processing and storage. The kinetics of the degradation reactions of chlorophyll pigments of the series “a” and “b” was studied at different temperatures (60, 80, 100 and 120 °C) in order to determine the thermodynamic parameters of these reactions in three VOO samples with high, medium and low pigmentation.
