摘要
应用酶联免疫吸附测定法和薄层色谱法,对安徽、河南部分地区1991年因特大洪涝灾害造成粮食霉变而引起食物中毒的小麦和大米样品,进行了霉菌毒素[黄曲霉毒素B_1(AFB_1)、脱氧雪腐镰刀菌烯醇(DON)、T-2毒素(T-2)及赭曲霉毒素A(OA)等]的检测。在测定的样品中,检出了高含量的DON和T-2。其中,霉变小麦中,T-2的污染阳性率为96.9%。最高含量为1064.4μg/kg,平均含量为212.1μg/kg;6份霉变大米中,T-2平均含量达532.0μg/kg。
The mould samples (wheat and rice) collected from flooded area in Anhui and Henan Provinces in 1991 were determined for mycotoxins (Aflatoxin B1, Ochratoxin A, Deoxynivalenol and T-2 toxion) by competitive enzyme-linked immunosorbent assay(ELISA)and thin-layer chromatography. The high conentrations of T-2 toxin and deoxynivalenol were found in these samples. In 96.9% of these samples, T-2 toxin was detected. The highest concentration of T-2 toxin was 1064.4μg/kg; the mean concentrations of T-2 toxin were 212.2μg/kg in wheat and 532.0μg/kg in rice.
