This paper reviews several aspects of bleaching fats and oils. Bleaching is a relatively simple operation from a mechanical standpoint, however the underlying technical background of the reactions occurring in the oil is quite involved and frequently weird, and apparently inconsistent effects result. Specificially, the subjects covered are: (a) effect of bleaching upon the organic peroxides of the oil; (b) nature of the bleaching reaction; (c) variation of bleaching efficiency between clays upon different oils; and (d) filtration factors.
