【摘要】：目的了解陕西省谷物及其制品中真菌毒素污染情况。方法 2013年3月—2016年6月,在陕西省10个地级市采集玉米及其制品、小麦及其制品、大米和玉米油,采用高效液相色谱法检测其中的黄曲霉毒素(aflatoxins,AFT)和玉米赤霉烯酮(zearalenone,ZEN),超高效液相色谱-串联质谱法检测其中的伏马菌毒素(fumonisins,FBs)、脱氧雪腐镰刀菌烯醇(deoxynivalenol,DON)及其衍生物3-乙酰基-脱氧雪腐镰刀菌烯醇(3-A-Don)和15-乙酰基-脱氧雪腐镰刀菌烯醇(15-A-Don)。结果陕西省各种谷物中均检出真菌毒素,DON在小麦和玉米中的检出率分别为86.9%和74.2%,小麦及其制品中DON的超标率为6.7%,玉米没有超标样品检出。ZEN在玉米油和玉米中的检出率分别为79.4%和49.2%,玉米及其制品中ZEN超标率为6.3%。FB1在玉米中的检出率为72.5%。谷物制品中AFT检出率较低,主要污染玉米及其制品,检出率为5.0%。大米受真菌毒素污染较轻。结论 2013—2016年陕西省谷物制品普遍受真菌毒素污染,脱氧雪腐镰刀菌烯醇及其衍生物是检出率最高的一类真菌毒素,玉米是最容易受真菌毒素污染的谷物。
[Abstract]:Objective to investigate the contamination of mycotoxins in cereals and their products in Shaanxi Province from March 2013 to June 2016. Methods Corn and its products, wheat and its products, rice and corn oil were collected from 10 prefectural cities in Shaanxi Province from March 2013 to June 2016. High performance liquid chromatography (HPLC) was used to detect aflatoxins (AFT) and zearalenone (ZENN), and ultrahigh performance liquid chromatography-tandem mass spectrometry (HPLC-MS) was used to detect fumonisins (FBsN), deoxynivalenolDON (deoxynivalenolDON) and its derivatives (3-acetyl). Results the detection rates of mycotoxin don in wheat and maize were 86.9% and 74.2%, respectively. The detection rate of DON in corn oil and corn was 79.4% and 49.2% respectively. The detection rate of ZEN in corn and its products was 72.5% in maize. The detection rate of AFT in corn products was lower than that in corn products. The main contamination rate of corn and its products was 5.0. The rice was slightly polluted by mycotoxins. Conclusion the grain products of Shaanxi Province were generally contaminated by mycotoxins from 2013 to 2016. Deoxynivalenol and its derivatives are the most detectable mycotoxins, and corn is the most susceptible to fungal toxin contamination.
