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.
