摘　　要：旨在研究多层复合膜在进行橄榄油总迁移量实验过程中的关键点。将样品制成1.20 dm^(2)的试样,按照标准GB31604.8—2021进行橄榄油中总迁移量的测试。结果发现,相同材质样品水分敏感判定结果不同,水分敏感样品调理与不调理,橄榄油总迁移量结果差异大;试样挥发物测定的实验结果也会影响到最终总迁移量的值,不同的多层复合膜的试样挥发物测定结果不同;复合膜由于材质不同,对橄榄油的吸附能力不同,萃取橄榄油会影响结果判定。因此,橄榄油中总迁移量的测试结果应充分考虑到试样水分调理、挥发物测定、橄榄油萃取次数等步骤,以保证测试结果的准确性。This paper aims to investigate the key points for olive oil total migration test for multilayer laminated films.The samples were made into 1.20 dm^(2)specimens.The tests of total migration in olive oil were carried out according to the standard GB31604.8—2021.It was found that the results of moisturesensitive determination for the same material samples were various.The results of olive oil total migration differed greatly between conditioned and unconditioned moisture-sensitive samples.The test results of the volatiles measurement of the specimens also affected the final value of the total migration.Concurrently,the results of the volatiles measurement of the specimens of different multilayer composite films were different.Due to the different materials,the laminate membrane had different adsorption capacity for olive oil.The result determinations were affected by the completeness of olive oil extraction.Therefore,the test results of total migration in olive oil should fully consider the steps of specimen moisture conditioning,volatile matter determination and the number of olive oil extraction to ensure the accuracy of test results.
