12012—2015年陕西省市售食品中黄曲霉毒素的污染调查显示文摘目的了解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。胡佳薇 田丽 王彩霞 乔海鸥 王敏娟 2016卫生研究2016,45,5:9
2Toxicology,biosynthesis,bio-control of aflatoxin and new methods of detection显示文摘Mycotoxins and their derivatives since their discoveries and until the present time are behind unspecified economic and medical damages.Aflatoxins are classified according to their physical–chemical and toxicological characters in the most dangerous row of the mycotoxins.These aflatoxins are in part responsible,of irreversible medical disasters that are not easily manageable such as cancer of the liver and kidneys,and in the other part,of losses in the stored cereal products.Based on these crucial findings,monitoring of this toxin became imperative in post-harvest food products,during storage,during transformation chain and even during the long phases of conservation.Vigilance of this toxin is delivered by detection methods using very advanced technologies to respond in the shortest possible times.In addition,the knowledge of factors supporting the biosynthesis of aflatoxins such as the temperature,moisture content,concentration of nitrogen and carbon,and the molecules responsible for the genetic control of the synthesis will be reflected later in the choice of bio-control techniques.This control is currently based on new strategies using the bioactives substances of the plants,the lactic bacteria and some strains of actinomycetes that have good inhibiting activity against aflatoxins with fewer side effects on Man.On the other hand,this brief review summarizes the results of new studies demonstrating the toxicity of the toxin,new detection methods and bio-control.Mohamed Amine Gacem Aminata Ould El Hadj-Khelil 2016Asian Pacific Journal of Tropical Biomedicine2016,6,9:2
