Wrong about olive oil that never need hexane extraction. Hexane is used to do a second extraction of the residues from the first extraction, to increase the yield. Of course it is somewhat poisonous. It is done for most cheap olive oil ! When buying olive oil, you have to make sure it is extracted mechanically and not chemically, in France at least it is written as such.
I've never encountered chemically extracted olive oil, thanks god! I didn't knew they used it. it makes sense, just to increase the yield..
I've only seen mechanically extracted extra virgem olive oil.
I've seen some mixtures of like 80% vegetable oils with 20% natural extra virgin olive oil..
