目的了解2012—2015年陕西省市售食品中黄曲霉毒素的污染状况。方法2012—2015年,在陕西省10个地市随机采集八大类食品,包括谷物及其制品(大米、玉米粉)、豆及豆制品(黄豆)、植物油(花生油、玉米油)、坚果及籽类(花生、开心果、杏仁等)、调味品(酱油、辣椒及花椒制品)、酒类(啤酒)、茶叶制品及特殊膳食用食品(婴幼儿辅食),采用超高效液相色谱仪对4种黄曲霉毒素进行了检测,并以GB 2761—2011《食品安全国家标准食品中真菌毒素限量》为标准进行评价。结果1007份样品中,有108份检出黄曲霉毒素,检出率为10.7%,平均值为2.34μg/kg。只有5份花生样品黄曲霉毒素B_1超标,超标率为13.5%。结论陕西省市售食品中黄曲霉毒素含量总体处于安全水平,但花生样品有潜在危险性,超标率较高。
Objective To understand the status of aflatoxins in commercial foods in Shaanxi Province from 2012 to 2015. Methods From 2012 to 2015, eight categories of foods including cereals and their products (rice and corn meal), beans and soy products (soy beans), vegetable oils (peanut oil, corn oil), nuts and seeds (Peanuts, pistachios, almonds, etc.), condiments (soy sauce, pepper and pepper products), alcoholic beverages (beer), tea products and special dietary foods (infant food supplement), using ultra performance liquid chromatography The aflatoxin was tested, and evaluated according to the standard of GB 2761-2011 “National standard of food safety for mycotoxins”. Results Among 1007 samples, 108 were detected aflatoxins, the detection rate was 10.7% with an average value of 2.34 μg / kg. Only 5 peanut samples aflatoxin B 1 exceeded the standard rate of 13.5%. Conclusion The content of aflatoxins in commercial products in Shaanxi Province is generally at a safe level, but the peanut samples are potentially dangerous with the over-standard rate being higher.
