Abstract

To investigate Fusarium mycotoxin contamination in rice samples from rice processing complexes (RPCs), paddy rice and rice-milling products such as husks, brown rice, blue-tinged rice, broken rice, rice bran, discolored rice, and polished rice were collected from nationwide in 2012. Three hundred seventy one samples of rice and its by-products were analyzed for three trichothethenes including nivalenol (NIV), deoxynivalenol (DON), and zearalenone (ZEA) by LC/MS. Discolored rice samples were found to have the highest contamination of DON, NIV or ZEA, followed by broken rice. Polished rice samples were largely free from mycotoxins, except three samples which were contaminated with NIV or DON at safety level. The rice byproduct samples were contaminated at higher level and frequencies than polished rice samples.

미곡종합처리장에서 수집한 2011년산 쌀 시료 중 Fusarium 곰팡이독소의 자연발생을 조사하기 위해서, 벼, 왕겨, 현미, 청치미, 싸라기, 미강, 색채미, 백미 등의 시료를 2012년에 전국적으로 수집하였다. 371점의 시료에 대해 DON, NIV과 ZEA의 자연발생을 LC/MS로 분석하였다. 이중 색채미가 오염율과 오염도가 가장 높았고 다음이 싸라기였다. 백미는 3점이 DON, NIV에 안전한 수준으로 오염되었었지만 나머지는 곰팡이독소가 검출되지 않았다. 부산물은 백미보다 오염도나 오염율이 높았다.
