摘要
目的了解2019年云南省市售散装大米中多组分真菌毒素污染状况。方法在云南省11个州市地区采集市售大米样品90份,采用超高效液相色谱-质谱(UPLC-MS/MS)检测16种真菌毒素。结果 90份大米样品中,黄曲霉毒素B1(AFB1)的检出率为13.33%(12/90);超过GB 2761—2017《食品安全国家标准食品中真菌毒素限量》规定(10μg/kg)的样品共9份,超标率为10.00%(9/90),其他种类真菌毒素均未超过限量标准。结论云南省市售散装大米受多种真菌毒素污染,但污染水平较低。
Objective To elucidate the natural occurrence of multi-mycotoxin in commercial loose-packed rice from Yunnan Province in 2019. Methods A total of 90 rice samples collected from 11 cities in Yunan Province were analyzed for 16 kinds of mycontoxin by ultra perfermance liquid chromatography-tandem mass spectrometry. Results Among the 90 rice samples, the detection rate of aflatoxin B1(AFB1) was 13.33%(12/90), exceeding the 10 μg/kg stipulated by the national food safety standard GB 2761-2017 for the limit of mycotoxin in food, and the exceeded rate was 10.00%(9/90). Other mycotoxins did not exceed the limit. Conclusion The commercial loose-packed rice samples in Yunnan Province were contaminated by multi-mycotoxins in this study, but the levels of contamination were low.
