옥수수기름의 제조공정 단계별 공정유 및 이 과정에서 발생되는 부산물에 함유되어 있는 B(a)P 함량을 측정하고 이의 제거방안에 대하여 연구하였다. 옥수수기름에서 높은 수준의 B(a)P가 검출되는 원인은 옥수수에 함유되어 있는 B(a)P의 80% 이상이 옥수수 배아에 집중적으로 분포하는데 따른 현상이었다. 이로부터 얻어진 원유를 일반적인 정제공정을 거칠 경우 최종 탈취유에서는 /kg가 검출 되었다. 따라서, 옥수수기름에서 일반적인 정제공정에 의해서

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 , after the usual refining process. B(a)P contents less than could not be attained by routine refining process. However, deodorized corn oil, with B(a)P level of , 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 mesh, removal of B(a)P from bleached corn oil was efficient at this mesh size.
