摘　　要：目的了解河南省市售粮食及其制品中真菌毒素污染的种类和程度。方法2018—2019年采集河南省市售粮食及其制品,采用同位素稀释超高效液相色谱-串联质谱(UPLC-MS/MS)法测定16种真菌毒素含量,检测结果按照GB 2761—2017《食品安全国家标准食品中真菌毒素限量》进行评价分析。结果100份玉米面、玉米渣及玉米粒中伏马菌素、玉米赤霉烯酮、黄曲霉毒素、脱氧雪腐镰刀菌烯醇是主要污染真菌毒素,检出率范围为0.0%~95.7%;220份小麦粉、面条和馒头中脱氧雪腐镰刀菌烯醇检出率分别为78.0%(124/159)、64.3%(18/28)和87.9%(29/33);其他真菌毒素含量较低或未检出。结论河南省粮食及其制品中存在不同程度的真菌毒素污染问题,尤其是玉米及其制品中伏马菌素有较高的检出率,应及时开展溯源调查,尽快采取相应控制措施。Objective To understand the types and extent of mycotoxins in grains and its products sold in Henan Province.Methods During 2018-2019,16 kinds of mycotoxins were detected by isotope dilution ultra high performance liquid chromatography tandem mass spectrometry(UPLC-MS/MS).The results were evaluated and analyzed according to GB 2761-2017 national food safety standard mycotoxin limit in food.Results Fumonisin,zearalenone,aflatoxin and deoxynivalenol were the main mycotoxins in 100 corn flour,corn dregs and corn kernels,the detection rate ranged from 0.0%to 95.7%.The detection rates of deoxynivalenol in 220 wheat flour,noodles and steamed bread were 78.0%(124/159),64.3%(18/28)and 87.9%(29/33)respectively,and the content of other mycotoxins was very low or not detected.Conclusion There were different levels of mycotoxin pollution in grain and its products in Henan Province,especially fumonisin in corn and its products.It is necessary to carry out traceability investigation in time and take corresponding control measures as soon as possible.
