Olive oil extraction is the process of extracting the oil present in the olive drupes for food use. The oil is produced in the mesocarp cells, and stored in a particular type of vacuole called a lipo vacuole, i.e., every cell contains a tiny olive oil droplet. Olive oil extraction is the process of separating the oil from the other fruit contents (vegetative extract liquid and solid material). It is possible to attain this separation by physical means alone, i.e., oil and water do not mix, so they are relatively easy to separate. This contrasts with other oils that are extracted with chemical solvents, generally hexane. The first operation when extracting olive oil is washing the olives, to reduce the presence of contaminants, especially soil which can create a particular flavor defect called "soil taste".

Famous quotes containing the words olive, oil and/or extraction:
“Even when seen from near, the olive shows
A hue of far away. Perhaps for this
The dove brought olive back, a tree which grows
Unearthly pale, which ever dims and dries,
And whose great thirst, exceeding all excess,
Teaches the South it is not paradise.”
—Richard Wilbur (b. 1921)
“Eat what you can get.
Where’s the salt
in this dump of a village?
And, Lucky Man,
what’s the use
of a salty thing
if there’s no oil in it?”
—Hla Stavhana (c. 50 A.D.)
“Logic is the last scientific ingredient of Philosophy; its extraction leaves behind only a confusion of non-scientific, pseudo problems.”
—Rudolf Carnap (1891–1970)
