北京市地区小包装食用油中真菌毒素污染状况调查

Contaminations of mycotoxin in small package edible oil in Beijing

在北京市地区随机抽取120份小包装食用油,采用高效液相色谱法或液相色谱-质谱联用法检测AF、AFB1、ZEN、DON、OTA和FB 6种真菌毒素的含量,并进行危害性评估。结果表明:120份样品中,黄曲霉毒素和玉米赤霉烯酮的检出率分别为6. 67%和17. 50%,且检出黄曲霉毒素的食用油都为花生油,检出玉米赤霉烯酮的食用油都为玉米油,未检出其他真菌毒素;黄曲霉毒素虽然没有超出我国食用油真菌毒素的限量标准,但超出了欧盟的真菌毒素限量标准;玉米赤霉烯酮检出率虽然很高,但没有超出人体的每日最大耐受摄入量。

A total of 120 small package edible oil samples were randomly collected in Beijing.AF,AFB1,ZEN,DON,OTA and FB were detected by high performance liquid chromatography(HPLC)/liquid chromatography-tandem mass spectrometry(LC-MS/MS),and risk assessment was conducted.The results showed that within 120 edible oil samples,the detection rates of AF and ZEN were 6.67%and 17.50%respectively,and the edible oils that detected AF were peanut oil,the edible oils that detected ZEN were corn oil,and no other mycotoxins was detected in edible oils.Although AF did not exceed the limitation of mycotoxin in edible oil in China,it exceeded the limitation of mycotoxin in European Union.The detection rate of ZEN was high,but it did not exceed the provisional maximum tolerable daily intake of human body.
