- 摘要:
- 为了掌握哈尔滨市储藏玉米真菌毒素污染情况,在玉米采收后和出售前,分两个时段对哈尔滨市11个玉米种植面积较大区、县(市)的农民家中的“地趴”储玉米进行布点采样,利用QuEChERS的前处理方法结合超高效液相色谱串联质谱法检测玉米样品中的FAB1、ZEN和DON。结果表明:各个区、县(市)的玉米样品中均有真菌毒素的检出,黄曲霉毒素B1并未检出,ZEN和DON有检出且含量超标,单一样品受多种毒素复合污染的情况比较严重,真菌毒素的检出率为27.57%,超标率为4.15%;第一次采集的样品真菌毒素的检出率高于第二次采集的样品。
- Abstract:
- In order to control the contamination of mycotoxins in maize stored in Harbin,the samples were taken from Harbin farmers′ home in the 11 maize planting area.The sampling work were done in the period after harvest and before sale.QuEChERS and the super high performance liquid chromatography tandem mass spectrometry were used to detect FAB1,ZEN and DON in maize samples.The results showed that the samples of maize in each district and county(city) were detected by fungal toxin,and the aflatoxin B1 was not detected,and the levels of ZEN and DON were detected and excessive .The detection rate of mycotoxin was 27.57%,and the exceed rate was 4.15%.The detection rate of mycotoxins collected for the first time was higher than that of the second time.
