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 ...

In the present work, olive-crop yields and olive oil physico-chemical quality were studied after three and six years of olive mill wastewater (OMW) spreading at three levels (50, 100 and 200 m3 ha-1 year-1). Olive yield showed improvements with OMW level. Insignificant difference in oil content and oil quality indices of the control and treatments amended by OMW was observed. Moreover, olive oi...

objective(s):cutaneous leishmaniasis is a common and endemic disease in khorasan province in north-east of iran. the pentavalant antimony (sb v) is the mainstay of treatment that has many side effects and resistance to the drug has been reported. the microbicidal effect of ozone was proven in different microorganisms. since there is no study in this respect and to achieve a low cost and effecti...

Olive oil and table olives are rich sources of biophenols, which provides a unique taste, aroma and potential health benefits. Specifically, green olive drupes are enriched with oleuropein, a bioactive biophenol secoiridoid. Olive oil contains hydrolytic derivatives such as hydroxytyrosol, oleacein and elenolate from oleuropein as well as tyrosol and oleocanthal from ligstroside. Biophenol seco...

Antimicrobial activity has recently been demonstrated in olive products. The anti-bacterial effect was correlated with the presence of olive glutaraldehyde-like compounds such as the dialdehydic form of decarboxymethyl elenolic acid either free (EDA), linked to tyrosol (TyEDA) or to hydroxytyrosol (HyEDA). Hence, the bactericidal activity of these substances is due to their dialdehydic structur...

In plant tissues, enzymes implicated in the lipoxygenase (LOX) pathway are responsible for the hydroperoxydation of polyunsaturated fatty acids, ultimately leading to the production of small chemical species involved in several physiological processes. During industrial olive oil production, these enzymes are activated upon crushing and grinding of olive fruit tissue, subsequently leading to th...

Olive mills generate a large amount of waste that can be revaluated. This work aim to improve the production lignocellulolytic enzymes by solid-state fermentation using ultrasounds pretreated olive mill wastes. The composition of olive mill wastes (crude and exhausted olive pomace) was compared and several physicochemical characteristics were significantly different. The use of both wastes in S...

Color of fruits is a relevant parameter to determine ripeness and optimal harvest time. For olives 6 ripening phases based on skin color distribution have been defined. A widely used method by the olive oil and table olives producers is to inspect the olive surface, and estimate the color and ripening phase visually. This method is simple but it is highly subjective and imprecise. This paper pr...
