>completely different species?
My understanding is that 'extra virgin' is process, not species. My understanding is that the first press is 'extra virgin' and the much cheaper "pure" olive oil comes from processing the same seeds- "Extra Virgin" is just the first press, while 'pure' uses more advanced chemical engineering to get all of the oil (and less of the more volatile compounds that give 'extra virgin' it's taste) out of what is left over.
- sannee 8y agoThat would make sense - the previous slides talk about adulteration/faking the "olive" part, which had me confused.
- kale 8y agoA side effect of this is that the "pure" olive oil is much more stable and has a higher smoke point. Wikipedia lists "Extra Virgin" at 160C and "Refined" up to 243C. So if you're trying to create a non-stick surface on something, pure olive oil is better than virgin olive oil.
