As defined by the European Commission regulation No. 2568/91 and subsequent amendments, [1] the highest quality olive oil (extra-virgin olive oil) must feature a free acidity lower than 0.8%. Virgin olive oil is characterized by acidity between 0.8% and 2%, while lampante olive oil (a low quality oil that is not edible) features a free acidity ...
In this context, "acidity" is not chemical acidity in the sense of pH, but the percent (measured by weight) of free oleic acid. Olive oil acidity is a measure of the hydrolysis of the oil's triglycerides: as the oil degrades and becomes oxidized, more fatty acids are freed from the glycerides, increasing the level of free acidity and thereby ...
Canola oil requires 7.5 hours, for example, whereas extra virgin olive oil (EVOO) and virgin coconut oil will last over a day at 110 °C (230 °F) of continuous heat. [9] The differing stabilities correlate with lower levels of polyunsaturated fatty acids, which are more prone to oxidation.
“The more taste an olive oil has, the more health benefits,” as the compounds responsible for them also contribute to the oil’s taste, said Joseph R. Profaci, executive director of the North ...
Olive oil quality is equally dependent on the quality of the olives themselves and on the time they have to wait from harvesting to extraction, in addition to the extraction method itself. The two main agents that cause the degradation of olive oil are oxygen and light. Once an olive is harvested, it should be pressed within 24 hours.

Rancidification is the process of complete or incomplete autoxidation or hydrolysis of fats and oils when exposed to air, light, moisture, or bacterial action, producing short-chain aldehydes, ketones and free fatty acids.
