I don't use oils in or for food because it packs on pounds and is not good for the endothelium of the vessels to and from the heart (and whole body).
The processing of oils by chemical means and heat is not healthy. That is my opinion.
If processing is the most important part of it for you, then try fresh pressed oils. I've ordered sunflower oil and it was a delight, light colored, very little flavor. I keep it in the refrigerator. I've used it in salves for lips and skin.
