잡곡의 Fusarium 곰팡이독소의 오염 조사를 위해, 총 244개 잡곡시료(귀리, 수수, 율무, 기장)를 수확기 포장에서 2017년과 2018년에 수집하였다. 데옥시니발레놀(DON), 니발레놀(NIV), 제랄레논(ZEA)은 면역친화컬럼법과 UPLC를 이용하여 분석하였으며, 푸모니신(FUM)은 QuEChERS 방법과 LC-MS를 이용하여 분석하였다. 잡곡 시료 중 귀리의 NIV 오염수준은 120.0-3277.0 μg/kg로 다른 잡곡에 비해 가장 높았다. 율무에서는 DON이 최대 730.0 μg/kg 검출되었다. 기장의 NIV과 ZEA의 오염빈도는 각각 61.5% 와 57.9%로 높았으나 평균 오염량은 각각 75.6 μg/kg과 21.5 μg/kg로 안전한 수준이었다. 잡곡 시료 중 수수는 DON, ZEA, FUM의 오염빈도가 가장 높았으며, 2 종 이상의 Fusarium 독소 중복 오염률이 70.0%로 잡곡 평균 29.9%에 비해 높았다. 잡곡 재배포장에서 Fusarium 독소 오염을 안전하게 관리하기 위하여 독소 발생 모니터링과 함께 오염예방기술 개발 연구가 수행되어야 할 필요가 있다.

A total of 244 cereal samples (oat, sorghum, adlay, and proso millet) were collected from fields to examine the contamination of Fusarium mycotoxins in cereals during harvest season in 2017 and 2018. The contamination levels of deoxynivalenol (DON), nivalenol (NIV), and zearalenone (ZEA) were analyzed individually by using the immunoaffinity column clean-up method with ultra performance liquid chromatography, and fumonisins (FUM) were analyzed by using the QuEChERS method with liquid chromatography-mass spectrometry. Highest level of NIV contamination (120.0-3277.0 mg/kg) was observed in oat samples among the analyzed cereals. In the adlay samples, DON contamination was the highest (maximum level 730.0 μg/kg). The proso millet samples had a high frequency of detection of NIV and ZEA (61.5% and 57.9%, respectively), but the levels were low (average detection level of NIV, 75.6 μg/kg, for ZEA, 21.5 μg/kg). Among the cereal samples, sorghum had the highest contamination frequency of DON, ZEA, and FUM, and the co-occurrence of Fusarium mycotoxin was 70.0%, which was higher than the average of 29.9%. In order to safely manage Fusarium mycotoxin levels in cereals, continuous research on the development of contamination prevention technologies together with monitoring of mycotoxin contamination is needed.
