3. Bleaching: During bleaching, unwanted pigments are adsorbed physically and oil will become much clearer.
4. Deodorization: It is used to remove unacceptable odors by steam distillation, the odoriferous compound are stripped off with the help of live injected steam into heated oil under high vacuum pressure.
5. Dewaxing (necessary for cold areas)
