Role of Olive Seed in the Biogenesis of Virgin Olive Oil Aroma

Journal of Agricultural and Food Chemistry, 2003
Results obtained in a set of experiments point to an effective participation of olive seeds in the biosynthesis of olive oil aroma through the lipoxygenase pathway during the extraction process to produce virgin olive oil. Data showed that olive seeds should contain enzymatic activities metabolizing 13-hydroperoxides other than hydroperoxide lyase ...

Analysis of extra virgin olive oils from stoned olives

Journal of the Science of Food and Agriculture, 2004
AbstractThis paper focuses on comparing the main chemical characteristics of 16 fresh commercial samples of extra virgin olive oil obtained from four harvest years (1999–2002) and derived from both stoned and whole fruits. The qualitative and quantitative contents of minor polar compounds (MPCs) together with other reference analytical parameters ...

Chemical composition of virgin olive oils according to the ripening in olives

Food Chemistry, 2013
The aim of this study was the classification of olive oil according to the stage of ripeness of the olives used for its manufacture. A discriminant analysis was applied taking as dependent variables the fatty acids, triglycerides and sterols profile. The evolution of parameters of quality of the oils during ripening of the fruit has also been studied ...

Virgin Olive Oil Study (VOLOS): vasoprotective potential of extra virgin olive oil in mildly dyslipidemic patients

European Journal of Nutrition, 2004
In vitro, olive phenols exert potent antioxidant and enzyme-modulating activities.We comparatively evaluate, in mildly dyslipidemic patients, the vasoprotective potential of extra virgin olive oil.22 patients were administered 40 mL/day of either extra-virgin, i. e. phenol rich, or refined, i. e. phenol poor, olive oils (EVOO or ROO, respectively, with

Comparison of the Antioxidant Activities of Extra Virgin Olive Oils

Journal of Agricultural and Food Chemistry, 2002
The phenol content and antioxidant activity of extra virgin olive oils (EVOOs) differing in their origins and degradation degrees were studied. The o-diphenolic compounds typical of olive oil, namely, the oleuropein derivatives hydroxytyrosol (3',4'-dihydroxyphenylethanol, 3',4'-DHPEA), the dialdehydic form of elenolic acid linked to 3',4'-DHPEA (3',4'-

Prediction of stability in extra virgin olive oil

2006
n a previous investigation a phenomenological model, based on combined stability/instability indices, was set up to predict stability of extra virgin olive oil (EVOO). According to the model proposed, degradation of EVOO can be monitored by measuring parameters (degradation parameters) which have to be sensitive to oil degradation.
