The performance of olive oil during intermittent frying of potato slices and cod fillets was compared to those of selected vegetable oils (corn, oliveresidue and 50/50 mixture of olive and corn oils) using conditions resembling those used in home food preparations. The main scope of this study was to decide what is the best substitute for olive oil in home frying applications. Free fatty acid c...

Herein, we report a portable electrochemical biosensor based on butyrylcholinesterase (BChE) immobilized on carbon black (CB)-modified screen-printed electrodes (SPEs) for the detection of organophosphorous pesticides in olive oil. The BChE/CB-SPE biosensor was developed to detect paraoxon in standard solutions as well as in olive oil samples previously treated with the QuEChERS method to extra...

Lycopene is the main carotenoid in tomatoes and it has been hypothesised to be responsible for reducing the risk of some cancers and heart disease. The cooking of tomatoes with olive oil is a characteristic combination in the Southern Mediterranean diet. Previous studies have shown that the absorption of lycopene is greater from processed tomatoes than fresh tomatoes, since the processing break...

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...

The Mediterranean diet, in which olive oil is the primary source of fat, is associated with a low mortality for cardiovascular disease. Data concerning olive oil consumption and primary end points for cardiovascular disease are scarce. However, a large body of knowledge exists providing evidence of the benefits of olive oil consumption on secondary end points for the disease. Besides the classi...

BACKGROUND Olive oil is a major component of the Mediterranean diet suggested to be beneficial to counteract Alzheimer's disease. AIM OF THE STUDY Our objective was to examine the association between olive oil use, cognitive deficit and cognitive decline in a large elderly population. METHODS We followed 6,947 subjects with a brief baseline food frequency questionnaire and repeated cognitiv...

Climate change is undoubtedly the most imminent environmental issue the world is facing today. Climate changes could heavily affect olive oil producing areas, especially in the Mediterranean basin. Olive trees are tougher than vines and can thrive on many different terrains and under various climate conditions. Researchers reported that a key area of Spanish olive oil production in Catalonia ma...

Olive oil, an important component of the Mediterranean diet, is rich in polyphenols and is known to possess positive health effects relative to other dietary fats. In addition, the leaves of the olive plant (Olea europaea) contain similar phenolics (oleuropein, luteolin-7-glucoside, apigenin-7-glucoside, verbascoside and hydroxytyrosol) to those of olives and olive oil, although at higher conce...

Olive oil contains a vast range of substances such as monounsaturated free fatty acids (e.g., oleic acid), hydrocarbon squalene, tocopherols, aroma components, and phenolic compounds. Higher consumption of olive oil is considered the hallmark of the traditional Mediterranean diet, which has been associated with low incidence and prevalence of cancer, including colorectal cancer. The anticancer ...

Olive (Olea europaea), whose importance is mainly due to nutritional and health features, is one of the most economically significant oil-producing trees in the Mediterranean region. Unfortunately, the increasing market demand towards virgin olive oil could often result in its adulteration with less expensive oils, which is a serious problem for the public and quality control evaluators of virg...
