Effect of the maturation process of the olive fruit on the phenolic fraction of drupes and oils from Arbequina, Farga, and Morrut cultivars.
The purpose of the work was to investigate the effect of the maturation process of the olive fruit on the phenolic fraction of drupes and oils from Arbequina, Farga, and Morrut cultivars. The level in the phenolic content of olive drupes declines rapidly during the black maturation phase. A general decreasing trend was observed too in the phenolic content of olive oils during the ripening process in the three varieties studied. Important differences in the high-performance liquid chromatography profile between varieties were observed. These included the presence of very low amounts of lignans in olive oils proceeding from the Morrut cultivar, and the presence of three peaks after elution of 3,4-DHPEA-EDA in the Farga and Morrut cultivars, which could be used as differentiating parameters. Sensory profile differences were observed between olive cultivars and due to the ripening process.
