Synthesis of aroma compounds of virgin olive oil
Increasing the hydroperoxide lyase activity causes an increased synthesis of volatile compounds. The activity is rapidly inactivated during olive fruit milling
Ultrasound decreased processing time of olive debittering
Power ultrasound efficacy was evaluated to accelerate NaOH-free olive debittering. No undesirable changes were observed in ultrasound-assisted debittered olives. Olives treated by ultrasound had higher antioxidant activity
Argan and olive oils protect in a similar way, but olive oil more
Bioavailability of polyphenols and antioxidant capacity of argan oil is analyzed and compared with olive oil. Large proportions of polyphenols from argan oil are absorbed by intestinal cells
Effects on olive fruit and oil after inoculation of arbuscular mycorrhizal fungi
Olive fruits showed greater accumulation of hydroxytyrosol and p-hydroxybenzoic acid after mycorrhiza and calcite treated plants. Phenolics having hydrophilic structure were influenced more than those of lipophilic structure
Novel pectin present in new olive mill wastewater
Pectin showed highest oil holding capacity and emulsifier activity than citrus pectin. Pectin showed high antioxidant activities, acts like antioxidant fiber.
New agreement at the International Olive Council
During discussions the member countries agreed on the draft text which will serve as the basis for the negotiation of a successor agreement. The members of the Technical Committee also put forward proposals to the Council of Members, which agreed to leave the ethyl ester limit at 35 mg/kg for the 2015/16 crop yea
Olive oil imports increase in Russia, decrease in China
Russian imports of olive oil and olive pomace oil grew at a constant rate between 2000/01 and 2013/14. Aggregate imports into China recorded strong growth from 2001/02 until 2011/12 but in 2012/13 and 2013/14 imports decreased
Potassium is an essential macronutrient for olive tree
The overall impact of potassium and sodium nutrition plays down any indirect effect on stomatal limitation and rather demonstrates the centrality of these elements in photochemical processes of photosynthesis and photoprotection in olive tree
How much salt to conserve table olives?
For treated olives the minimum sodium chloride (salt) content is 5.0% in both standards and for other types of olives it is even higher
Analysis of mid infrared spectra for identification of olive oil defects
MIR combined with multivariate analysis to identify main defects in olive oil. Instrumental analysis distinguish extra virgin from lower quality olive oils
How a systemic fungicide can fight against the olive leaf spot
When significant defoliation occurs, strong bloom fails to develop and crop production is substantially reduced. The most favorite formulations employed to fight against this disease are copper based product
Olive oil is our best ally against the cold, snow and frost. Here's how to use it
Winter has arrived with arrogance and is being felt, even on our skin. Face and hands are put to a severe test. The extra virgin olive oil can give lipids to the skin, to protect and nourish
A small-scale pyrolysis–biochar based system in symbiosis with an olive mill
Pyrolysis of agri-residues targeting biochar can fulfill the aim of closing the loop in agriculture and circular economy objectives
International buyers shocked by olive oil prices
The most sensitive markets seem to be those that do not produce olive oil themselves, such as Japan, where news of the poor olive oil campaign is not well-known
Prediction of the antioxidant activity of extra virgin olive oils produced in the Mediterranean area
The proposed method could be used for monitoring oil quality in terms of nutraceutical properties. K225 is effective for estimating the oil antioxidant activity, expressed with IC50
Efficacy of olive oil mill extract in replacing sulfur dioxide in wine model
The extract showed antimicrobial activity complementary to this of sulfur dioxide. Olfactometric profile was qualitatively similar to that of wine
Consumers dislike bitterness and pungency in olive oil
Extra virgin olive oils produced from olives of the same cultivars and grown in the same areas shared similar sensorial attributes
Enzymatic activity changed during olive leaf storage
Evidence of oleuropein degradation by olive leaf protein extract. An inhibitory effect of hydroxytyrosol on polyphenoloxidase activity was demonstrated
