Bleaching. Bleaching fats and vegetable oils is a part of comprehensive refining technology. The natural colour of fats comes from chlorophyll and from carotenes or lipochromes. The partial bleaching of oil occurs in degumming, but it is not sufficient and therefore bleaching based on the affinity of pigment dissolved or dispersed in oil to the
