Surely it doesn't need to be a solution - it can just be a suspension? The difference between extra virgin olive oil and purer grades are that the purer grades are filtered, not (e.g.) distilled.
- mack73 10y agoExtra means the oil contains no more than 0.8% of free oleic acid. Virgin means the oil comes from a mechanical process, not a chemical one. The purest grade extra virgin olive oil is the first cold pressed. It's neither filtered nor distilled. Refined olive oil however is filtered and also tasteless. https://en.wikipedia.org/wiki/Olive_oil#Commercial_grades https://en.wikipedia.org/wiki/Olive_oil#Commercial_grades
- NLips 10y agoFrom the same page: "The refining process removes colour, odour and flavour from the olive oil, and leaves behind a very pure form of olive oil that is tasteless, colourless and odourless and extremely low in free fatty acids" I don't mean 'pure' in a good sense, just that it is a simple mixture.
