Optimisation of extra virgin olive oil quality

Journal of the Science of Food and Agriculture, 1998
This study investigated the correlation between total polyphenol content and the stability (ie induction time by Rancimat) of oil samples according to different regions, cultivars, extraction technologies and ripening times of raw material. Results indicate a correlation of oil stability with total polyphenols, (r=0·88), a chemical variable easy to ...

Antioxidant Activity of Methyl Caffeate‐Enriched Olive Oils: From Extra Virgin Olive Oil to Extra Virgin Olive Oil‐Based Microemulsions

European Journal of Lipid Science and Technology, 2022
AbstractOxidative rancidity isthe main cause of extra virgin olive oil's (EVOO) quality deterioration. Here, methyl caffeate (CAME) is examined for possibly enhancing EVOO antioxidant activity. To improve CAME's solubility and efficacy, an EVOO‐based water in oil microemulsion is used. The oxidative stability of EVOO is monitored.

Extra Virgin Olive Oil's Polyphenols: Biological Activities

Current Pharmaceutical Design, 2011
In addition to its high proportion of oleic acid (which is considered as "neutral" in terms of cardioprotection), extra virgin olive oil is rich in phenolic compounds, which other vegetable oils do not contain. This review critically appraises the current scientific evidence of a healthful role of olive phenols, with particular emphasis on ...

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 ...
