PDF Physical Refining of Sunflower Oil

Crude sunflower oil, which has reached a certain level of oxidation is difficult to refine. There are two main difficulties: removal of non-hydratable phospholipids/iron and sometimes when the autooxidation has really gone too far fix colour formation, which is not removable by bleaching and/or heat bleaching.
