Olive oil more stable and healthful than seed oils for frying food

Researchers from Tunisia note that different oils have a range of physical, chemical and nutritional properties that can degrade oil quality when heated. Some of these changes can lead to the formation of new compounds that are potentially toxic

Italy and Pakistan together. Insights on a local and wild promising cultivar

The oils obtained from olives of the species Olea ferruginea showed a chemical composition similar to that typical of the oils obtained from Olea europaea, except for negligible amounts of erucic acid and brassicasterol and a small presence of linoleic acid, slightly more than 1%.

The olive oil production will stop to 2.560.000 tons

Bad harvest in Spain and great in Greece. Higher imports by Canada, the United States, Australia and Japan and lower import levels in China and Brazil

The University of Pisa patented new method of extracting extra virgin olive oil

The advantages of the innovative technique are many: a higher yield, improved nutritional quality of the oil and a greater resistance to oxidative processes

How to purify olive mill wastewater?

Simultaneous removal of pollutant ions from model water simulating secondary treatment. Researchers used a combination of Dowex Marathon-C + Amberlite IRA-67 resins

The outlook of the olive oil production in the Mediterranean basin

A bad harvest year in Spain and Italy, instead Greece and Tunisia celebrate record harvests. It will be a difficult campaign, not only for the quality, but also for the amount of olive oil. The global demand may exceed supply

The Italian way for olive oil traceability

The extracted DNA is stable overtime and amenable for molecular analyses but there is also the possibility of using the chromatographic fingerprint of the phenolic fraction of extra virgin olive oils coupled to chemometric classification techniques

New olive oil quality standards to be introduced in California

The standards, which are based on scientific research at the UC Davis Olive Center, are unique to California production will establish a more stringent limit for free fatty acids, a negative attribute that signals a breakdown of olive oil quality due to exposure to heat, light and oxygen

Extra virgin olive oil against arthritis

The scientific results support the interest of natural diet components in the development of therapeutic products for arthritic conditions

The real quality of the aromatized olive oils

Diverse flavoured olive oils were compared for composition. Differentiated effects were observed and corroborated by chemometrics but garlic and oregano decreased the formation of primary oxidation products.

Characterization of antioxidant enzymes and peroxisomes of olive fruits

In olive fruit tissue the presence of a battery of antioxidant enzymes was demonstrated, including catalase, four superoxide dismutase isozymes

Phenolic bioaccesibility and bioavailability rises in olive oil and thyme extracts

In vitro bioaccessibilty of hydroxytyrosol increases in presence of thyme. Olive and thyme co-exposure in Caco-2 led to higher bioavailability of eriodictyol and naringenin

Spanish olive harvest will be poor next Autumn due the severe drought

In the last weeks the prices of extra virgin and olive oil increased till 2,8 euro/kg in Spain and 4 euro/kg in Italy. The last drought season, in 2012/13, elevated US imported olive oil prices by 8%

Not all extra virgin olive oils have so much health effects

Phenol enriched virgin olive oil improves human endothelial function. The benefits associated with polyphenol-rich olive oil consumption on cardiovascular risk could be mediated through an in vivo nutrigenomic effect in humans

Fertilization induces qualitative changes in the mineral composition of olive fruits

Foliar nutrient fertilization causes a decrease of total phenols and tocopherols. Qualitative changes also in phenols and carbohydrates profiles. The results elucidated an evident association between environmental concentrations of nutrients and chemical composition of olive fruits

In Toledo to discuss markets, health benefits, culinary uses and quality standards of extra virgin olive oil

The next International Extra Virgin Olive Oil Savantes programme will be held at Hotel Fontecruz Toledo, in Toledo, Spain on 24th-26th September 2014

When the extra virgin olive oil acidity increases so much?

A countrywide survey elucidated major reasons for high acidity in olive oil. Geographic and environmental factors had no significant effect on oil acidity. High oil acidity evolved particularly from fungus-infected, fully ripened fruit
