Vegetable oil is an oil obtained by pressing seeds (sunflower, peanut, etc.), from fruits (coconut, etc.) or by chemical extraction with solvents.
There is a bit of everything in this term, so when you find it on a food label the question comes up: but which vegetable oil ?
Moreover, the extraction process is not usually indicated: cold, hot , chemical ?
In any case, this oil is better than hydrogenated oil that is obtained by various chemical processes that degrade the positive organoleptic qualities.
Thus, vegetable oils can come from many different plant sources, such as sunflower seeds, olives, corn, canola, and many others.
