    摘要:

    为掌握山东省玉米的真菌毒素污染状况,评估污染带来的安全风险,为加强真菌毒素污染防控提供依据,采集了山东省玉米主产县2013年~2014年收获和储藏的玉米样品共520批次,采用液相色谱一飞行时间质谱联用仪(UPLC-Q-TOF)方法检测了玉米中黄曲霉毒素 (AFB1、AFB2、AFG1、AFG2)、伏马毒素(FB1、FB2、FB3)、呕吐毒素(DON)和玉米赤霉稀酮(ZEN)的 污染水平。结果表明,AFB1、AFB2、AFG1在玉米中检出率分别为18.08%、7.88%、0.77%,平均含量分别为 7.62、0.60、0.05 µg/kg;FB1、FB2、FB3检出率分别为 92.50%、88.08%、83.85%,平均含量分别为 1798.69、531.83、197.71 µg/kg;DON检出率为 26.35%,平均含量为240.44 µg/kg;ZEN检出率为14.62%,平均含量为74.90 µg/kg;AFG2未检出。调查结果还表明,伏马毒素在所测样品中污染最为严重,超标率达33.46%;单一样品受多种毒素混合污染的情况较严重。

    Abstract:

    The liquid chromatography-time of flight mass spectrometry was used to detect the contamination level of aflatoxin (AFB1, AFB2, AFG1, AFG2), fumonisin (FB1, FB2, FB3), deoxynivalenol (DON) and zearalenone (ZEN) on the maize samples harvested during 2013~2014 in Shandong province, 520 batches. The results showed that the detection rates of AFB1, AFB2, AFG1 were 18.08%, 7.88% and 0.77%, the average contents were 7.62 µg/kg,0.60 µg/kg and 0.05µg/kg; the detection rates of FB1, FB2, FB3 were 92.50%, 88.08% and 83.85%, the average contents were 1798. 69 µg/kg, 531.83µg/kg and 197.71 µg/kg; the detection rate of DON was 26.35%, the average content was 240.44 µg/kg; the detection rate of ZEN was 14.62%, the average content was 74.90 µg/kg. While none of maize samples were contaminated by aflatoxin G2. In addition, the results indicated that FBs contamination in maize was one of the most severe problem, and the over standard rate was 33.46%, and the other severe problem was the composite contamination by multiple mycotoxins.
