Resumen
[es] Se han analizado siete muestras de aceite de oliva virgen (AOV) obtenidas a partir de aceitunas de la variedad Picual, cultivadas en régimen de secano y recolectadas en diferentes estados de maduración de los mismos árboles.
En estas muestras se han determinado polifenoles totales, ortodifenoles, flavonoides y capacidad antioxidante (método DPPH). Se ha relacionado el contenido de antioxidantes naturales en las muestras de aceite con el índice de madurez (IM) de las aceitunas de las cuales se ha extraído el aceite.
Una vez obtenido los datos experimentales en el laboratorio, se han discutido los resultados y comparado con la bibliografía consultada.
[en] Seven samples of virgin olive oil (AOV) obtained from olives of the Picual variety, grown in rainfed conditions and collected in different stages of maturity from the same trees, have been analyzed. In these samples, total polyphenols, orthodiphenols, flavonoids and antioxidant capacity have been determined (DPPH method). The content of natural antioxidants in the oil samples has been related to the maturity index (MI) of the olives from which the oil has been extracted. Once the experimental data had been obtained in the laboratory, the results were discussed and compared with the bibliography consulted.
