| 摘 要： | 考察了钴-60不同辐照剂量（0、1．5、3、5、10、15kGy）所产生的γ射线对花生油中黄曲霉素B1（AFB1）含量的影响。研究发现，经过不同剂量辐照处理后，AFB1的含量均有所下降，且AFB1的降解率随辐射剂量的增加而增加，随AFB1浓度的增加而增大；辐照后，各组花生油中AFB1含量均下降到10μg／kg以下，符合国家标准的要求。各组花生油中的过氧化值较辐照前略有升高；辐照后，油酸含量的最高值为43．2％，最低为40．3％；亚油酸的最高含量为35．4％，最低为33．3％；棕榈酸的最高含量为11．8％，最低为10．3％；而硬脂酸的最高含量为5．4％，最低为4．7％。经过统计，各AFB1添加组花生油中油酸、亚油酸、棕榈酸、硬脂酸的组成含量没有明显的差异。

| Abstract: | The effect of gamma-ray produced by different doses of cobalt-60 on the AFB1 content in peanut oil was studied. The results showed that AFB1 content decreased after irradiation of different doses, and the degradation rate of AFBl increased with the rise of the radia-tion dose and the concentration of AFB1. After irradiation, AFB1 content in peanut oil of each group dropped to less than 10μg/kg, which met the national standard. The peroxide value of each group peanut oil increased slightly after irradiation. The irradiation had no significant effect on the composition and content of oleic acid, linoleic acid, palmitic acid and stearic acid and other fatty acids in each group peanut oil. |
