摘要
目的:调查分析2022年云南省昭通市新收获玉米真菌毒素污染情况。方法:采集2022年昭通市各县区100份玉米样品,分别采用高效液相色谱-柱后衍生法、免疫亲和层析净化高效液相色谱法、液相色谱法测量黄曲霉毒素B1、脱氧雪腐镰刀菌烯醇、玉米赤霉烯酮。结果:71份玉米样本未检测出真菌毒素,29份样本检测出真菌毒素,所有样本真菌毒素均未超标,脱氧雪腐镰刀菌烯醇总体检出率最高。盐津县有1份检出3种真菌毒素的玉米样本,巧家县有3份检出2种真菌毒素的玉米样本,且脱氧雪腐镰刀菌烯醇与玉米赤霉烯酮检出率最高,巧家县和绥江县所收样本脱氧雪腐镰刀菌烯醇检出率最高,巧家县和水富市所收玉米样本赤霉烯酮检出率最高。结论:昭通市2022年新收获玉米真菌毒素污染情况在合理范围内,盐津县、巧家县新收获玉米易受真菌毒素污染,需加强关注。
Objective:Investigation and analysis of mycotoxin pollution of newly harvested maize in Zhaotong city,Yunnan province in 2022.Method:A total of 100 corn samples were collected from counties and districts of Zhaotong city in 2022.Aflatoxin B1,deoxynivalenol and zearalenone were measured by high performance liquid chromatography,purified high performance liquid chromatography by immunoaffinity chromatography,respectively.Result:Mycotoxins were not detected in 71 maize samples,mycotoxins were detected in 29 samples,and mycotoxins were not exceeded in all samples.Deoxynivalenol had the highest overall detection rate.There was one sample of corn with 3 mycotoxins detected in Yanjin county,and three samples of corn with 2 mycotoxins detected in Qiaojia county,and deoxynivalenol and zearalenone had the highest detection rates.The samples collected from Qiaojia county and Suijiang county had the highest detection rate of deoxynivalenol,and the samples collected from Qiaojia county and Shuifu city had the highest detection rate of gibalenone.Conclusion:The mycotoxin pollution of newly harvested corn in Zhaotong city in 2022 is within a reasonable range,and the newly harvested corn in Yanjin county and Qiaojia county is susceptible to mycotoxin pollution,which needs to be paid more attention to.
