dc.description.abstract
"Arauco" is the only olive (Olea europaea L.) cultivar recognized from Argentina in the World Catalogue of Olive Varieties. Drupes from this cultivar were handpicked at different stages of fruit development and ripening-referred to as days after full flowering (DAFF)-and analyzed to assess the oil accumulation pattern, and the dynamic of the changes in fatty acid, tocopherol, squalene, and phenolic compositions. The most intense oil accumulation period occurred approximately between 80 DAFF (pit hardening) and 150 DAFF (beginning of fruit maturation). Oleic acid content increased rapidly until reaching the maximum concentration (71.4%) approximately 80 DAFF, thus indicating that the most active biosynthesis period occurred at early fruit growth stages. Later, oleic acid content decreased gradually, almost linearly, to 62% at the final sampling point (215 DAFF). The dynamic of tocopherol accumulation showed a trend characterized by high amounts of the α- and γ-isoforms in very young drupes, a pronounced decrease during fruit development, and little or no change during the fruit maturation period. The developing drupes were found to accumulate significant amounts of squalene (up to 12 500mg/kg of dry weight at 96 DAFF), but squalene dropped strongly after the beginning of fruit ripening. Whatever the stage of fruit development, secoiridoids were the major phenolic components. On the basis of the evolution of the analytical parameters studied, the best stage for processing "Arauco" fruits for oil production seems to be that where maturity index is higher than 1 and lower than 2. Practical applications: The study focuses on biochemical aspects of oil biogenesis and minor antioxidant compounds from the cv. "Arauco" during fruit ontogeny. The results show that this cultivar has profitable characteristics for commercial production of VOO. From a practical standpoint, results also contribute to better assessment of harvest time. Findings remark on the convenience of harvesting early (at a low fruit maturity index) to get the best combination of oil quantity and quality.
