摘　　要：主要研究了不同剂量的辐照处理(5kgy~50kgy)对食品接触材料PE膜、CPP膜总迁移量的影响。试验结果表明当辐照剂量不大于50kgy时,PE膜和CPP膜的总迁移量受辐照剂量的影响不显著,其中在使用相同的迁移试验条件下,PE膜进行4%乙酸的食品模拟物迁移测试得出的总迁移量值最大,CPP膜进行95%乙醇(植物油替代物)的食品模拟物迁移测试得出的总迁移量值最大。The effects of different doses of irradiation(5 kgy~50 kgy)on the total migration of PE and CPP films of food contact materials were studied.The experimental results show that when the radiation dose is less than 50 kgy,the total migration of PE film and CPP film is not significantly affected by the radiation dose.Under the same migration test conditions,the total migration value of PE film is the largest when the food simulant migration test is carried out with 4%acetic acid.CPP membrane for 95%ethanol(vegetable oil substitute)food simulation migration test obtained the largest total migration value.
