福建省市售花生及花生制品中4种黄曲霉毒素污染调查

目的:了解福建省花生中黄曲霉毒素B1(AFB1)、黄曲霉毒素B2(AFB2)、黄曲霉毒素G1(AFG1)和黄曲霉毒素G2(AFG2)的污染状况。方法:从福建省九个地区采集花生和花生制品,用高效液相色谱测定黄曲霉毒素含量。结果:共测定62份花生,40份花生酱,20份花生油。以国家标准规定的黄曲霉毒素B1限值20μg/kg计,超标率分别为17.7%、37.5%和0。4种毒素中AFB1阳性率和平均浓度最高,AFB2、AFG1和AFG2的阳性率和平均浓度依次降低。结论:福建省花生和花生制品的黄曲霉毒素污染比较普遍,4种毒素中以AFB1污染为主。

Contamination of aflatoxins in peanuts and peanut products from Fujian

Objective:To investigate the contamination of Aflatoxins(AFs) in peanuts and peanut products in Fujian.Methods:The samples were collected from 9 regions in Fujian.The levels of Aflatoxins were determined by high performance liquid chromatography.Results:62 peanut samples,40 peanut butter samples and 20 peanut oil samples were determined.According to the limit of Aflatoxin B1,the over-limit rates of peanut,peanut butter and peanut oil were 17.7%,37.5%,0.AFB1 was detected more frequently with higher levels than the other three AFs.The positive rates and average concentrations of AFB2,AFG1 amd AFG2 in these samples decreased in turn.Conclusion:Peanuts and peanut products were contaminated with Aflatoxins widely.AFB1 is the major pollution factor among the four AFs.
