FUMONISIN CONTAMINATION IN CORN AND PROCESSED CORN PRODUCTS COMMERCIALIZED IN KOREA

A survey for fumonisins(fumonisin B1, B2 and B3) was conducted on 131 corn and processed corn products commercialized in Korea. The fumonisins were determined by high-performance liquid chromatography(HPLC) with fluorescence detector using immunoaffinity column clean up. The Fumonisins were detected in 91 samples(69.4% of incidence) and they were 100% incidence in corn flour, corn cereal, and roasted corn. The contamination level was 0.01 mg/kg ~ 13.0 mg/kg and the whole kernel corn showed the highest contamination level(0~13.0 mg/kg, average 1.56 mg/kg). Based on the Korea food consumption data, estimated daily intake(EDI) of fumonisin was 0.03 ~ 0.08 ug/kg b.w./day.
