Steam refining of fatty oils to reduce the partially high free fatty acid content of certain crude oils before conventional refining has been practiced in Europe for many years. Intensive laboratory testing indicated that crude palm oil could be pretreated to remove trace metals and certain heat resistant organic compounds. This pretreated oil could then be steam refined and simultaneously steam deodorized to produce a high quality finished edible oil. Analytical data on crude and finished oil quality and operating yields are presented to illustrate the steam refining/deodorization process. Laboratory results obtained by steam refining a variety of other oils also are presented.
