| Abstract: |
| In order to understand the dietary exposure risk of aflatoxin B1 (AFB1)of Wuzhou residents through native pressed peanut oil from small workshops,a total of 496 batches of native pressed peanut oils in three districts and four counties of Wuzhou city were randomly selected and tested the AFB1 content, and the point assessment method was applied to assess the dietary exposure risk of Wuzhou residents to AFB1 in native pressed peanut oil. The results showed that the detection rate of AFB1 in 496 batches of native pressed peanut oil was 40.3%, and the content ranged from 0.12 μg/kg to 109.00 μg/kg, with an average content of 3.63 μg/kg and an exceedance rate of 4.64%, and the average dietary exposure of AFB1 was 1.67 ng/(kg·d), with a mean margin of exposure(MOE) of 240. The average dietary exposure of AFB1 was found to be lower among male residents than female residents, and lower among urban residents than rural residents, while the risk of AFB1 was found to be higher among female residents than male residents, and higher among rural residents than urban residents. The risk assessment results indicate that the potential risk of AFB1 intake by Wuzhou residents through native pressed peanut oil is high. |
