FYI....
Olive oil, and other vegetable oils, have various natural fatty acids in them. Virgin grades straight out of the seeds or fruit might show this even at normal room temperature as a milky look.
These fatty acids melt / solubilize at various temperatures. The milky oils if heated up will turn clear. There is a test where this point is checked and it is called cloud point.
Because some people think there is something wrong if they see this, manufacturers think it is best to remove these fatty acids. It stops phone calls and some customers returning stock.
So they chill the oil down to about 5C degrees to solidify these and filter the oil. This process is called ‘winterizing'. As in ‘in winter it will not get cloudy’. It shuts some people up, stops the phone calls and everybody is happy.
Except the people that now know that they no longer have the real pure ‘as nature made it' oil.
