Ozonated olive oil was prepared by bubbling ozone-oxygen gas through olive oil until it solidified. Hand C-NMR spectra of the ozonated oil showed that all C-C double bonds in triacyglycerols were converted to ozonide. The spectra also showed no other structural change and the absence of degraded products of ozonide such as aldehydes and carboxylic acids. HPLC chromatogram of the oil showed thre...

ABSTRACT: In this study, an analytical method is developed to determine 15 polycyclic aromatic hydrocarbons (PAHs) in olive and refined pomace olive oils using HPLC coupled with a fluorescence detector. The standardised method of ultrasound-assisted solvent extraction consisted of liquid–liquid extraction with organic solvent and purification on C18 and Florisil bonded-phase cartridges was modi...

olive cultivars with specific characteristics have been developed thanks to iran’s particular climatic conditionsand long-term olive cultivation. the genetic variation and relationships among 40 olive cultivars, as well as 17 unknown genotypes from the national olive collection orchard at tarom research station, zanjan, iran, were evaluated using ssr markers. using 10 microsatellite primer pair...

in the present study, the oxidative stability of nine iranian commercial olive oils, including four virgin samples and five deodorized ones, was compared to that of two foreign virgin olive oils. in total, the foreign samples had the mufa/pufa ratios (av. 9.27) higher than those of domestic ones (av. 5.70). the peroxide and acid values of the olive oils studied ranged from 8.5 to 14.5 meq/kg an...

The objective of the research was to highlight the role that socio-economic and spatial attributes of consumers – households exert on their choices regarding not only the supply modes but also the price they are willing to pay for different categories of olive oil. Regarding WTP for different olive oil labels, consumers are willing to pay premiums only for olive oils being processed by either p...

The world productions of olive oil reach 2,800,000 ton and 98% of this production is to be found in the Mediterranean basin, where this agricultural system has been developed for thousands of years, characterized by its adaptation to the environment and its empiricism. Several factors have modified the olive production and processing systems in the last decades. The crisis of traditional agricu...

In this study the energy and economic flows and greenhouse gas (GHG) emissions of olive oil production in Iran were investigated in terms of a life cycle assessment with considering four main stages of agricultural olive production, olive transportation, olive oil extraction and its oil transportation to the customer centers. Data was collected from 150 olive growers in Guilan province of Iran....

Oils enriched in monounsaturated fatty acids do not seem to behave similarly in protecting against the development of atherosclerosis in animal models, which has been attributed to the presence of soluble phenolic compounds. To test the relevance of other components of oils in the prevention of atherosclerosis, two olive oils from the same cultivar devoid of soluble phenolic compounds were prep...

The possible existence of altitudinal fluctuations in the seasonal behaviour of the olive pollen emission was studied. Three pollen volumetric samplers distributed in olive groves all over the altitudinal cliseries of the province of Jaén (south-east Spain) were used. Pollen emission data were recorded during a 3-year period (2007–2009). This research has revealed the effect of altitude on cons...

Olive oil is the major component of the Mediterranean diet and has rich history of nutritional and medicinal uses. In the present study, the antidepressant and anxiolytic effects and their neurochemical basis following repeated administration of extravirgin olive oil were monitored. Male albino Wistar rats were used during study. Animals of test group were given olive oil orally at the dose of ...
