Abstract
Benzo(a)pyrene[B(a)P] levels were determined in processed oils and by-products of corn oil, and removal protocol was formulated. The cause of high level B(a)P contents in corn oil was established. Corn germ had a B(a)P level more than 80% that of whole corn. B(a)P content in final deodorized corn oil was $2.15{\mu}g/kg$, after the usual refining process. B(a)P contents less than $2.0{\mu}g/kg$ could not be attained by routine refining process. However, deodorized corn oil, with B(a)P level of $0.09{\mu}g/kg$, could be prepared by treatment of oil with approximately 2% (w/w) mixed granules(acidic clay:active carbon= 90:10[w/w]). The optimal amount of active carbon was 10% (w/w) that of acidic clay;higher levels of active carbon was not required. The optimal particle size of active carbon was $50{\sim}100$ mesh, removal of B(a)P from bleached corn oil was efficient at this mesh size.
