Storage at 3 and 18 °C of 'Arbequina' olives (Olea europaea L.) cultivated in hedgerows and harvested manually or mechanically (wine grape harvester) was tested. Fruit characteristics and oil quality were monitored. Mechanical harvesting caused internal fruit damage that induced its rapid softening and decay, but also facilitated obtaining higher amounts of oil, which suffered a rapid deteriora...

The effect of different environmental stresses on the expression and enzyme activity levels of 13-lipoxygenases (13-LOX) and 13-hydroperoxide lyase (13-HPL) and on the volatile compounds synthesized by their sequential action has been studied in the mesocarp tissue of olive fruit from the Picual and Arbequina cultivars. The results showed that temperature, light, wounding and water regime regul...

In this work, we introduce an NMR-based screening method for the fatty acid composition analysis of edible oils. We describe the evaluation and optimization needed for the automated analysis of vegetable oils by low-field NMR to obtain the fatty acid composition (FAC). To achieve this, two scripts, which automatically analyze and interpret the spectral data, were developed. The objective of thi...
