玉米、花生黄曲霉毒素的污染分析

Study of Aflatoxin Pollution of Corn and Peanut

玉米和花生作为我国主要农作物,具有很高的食用和饲用价值。但两者极易受到黄曲霉毒素的污染,其质量安全问题成为大家关注的热点。本文对来自江苏省和河南省的玉米、花生样本进行黄曲霉毒素B_(1)、B_(2)监测,并对黄曲霉毒素B_(1)的污染现状、污染来源、保障措施进行对比、分析。我们发现,玉米、花生黄曲霉毒素B_(1)超标现象较为严重。在调查的样本中,参照不同的判定标准,食用玉米超标率为19.0%,饲用玉米超标率为4.0%,花生超标率为3.9%。对污染源进行分析,我们发现污染样本的生产主体多为农户,且抽样环节多为储存。

As the main crops in China,corn and peanut have high value for food and feeding.However,both of them are easily contaminated by aflatoxin.So,their quality and safety issues have become the focus of attention.In this paper,aflatoxin B_(1) and B_(2) were detected in samples of corn and peanut from Jiangsu Province and Henan Province.And pollution status,pollution sources and safeguard measures of aflatoxin B_(1) pollution were compared and analyzed.We found that the aflatoxin B_(1) of corn and peanut exceeded the standard seriously.In the investigated samples,according to different criteria,the over standard rate of edible corn,feed corn and peanut were 19.0%,4.0%and 3.9%respectively.Based on the analysis of pollution sources,we find that the main producers of contaminated samples were farmers,and the sampling link was storage.
