Olive oils were obtained from 10 kg olive fruits with the Abencor system (MC2 Ingenieria y Sistemas, Sevilla, Spain). Olive samples were washed after being separated from their leaves and crushed in a crusher. It was subjected to mixing (malaxation) at 25°C for 30 minutes. After malaxation, a centrifuge was used to separate the oil from the olive paste. The obtained olive oils were stored under controlled conditions in amber colored bottles at +4°C until the analyses were done after filtering.
