[Establishment of Test Methods for Overall Migration Test into Vegetable Oil Applied to Food Contact Materials Intended for Contact with Oils and Fatty Foods]. Shokuhin Eiseigaku Zasshi. 2018;59(5):193-199 Authors: Nakanishi T, Kawamura Y, Joichi K, Watanabe Y, Sugimoto T, Abe Y, Mutsuga M Abstract The evaporation residue test designated in the Japanese Food Sanitation Act is used to determine the total migration amount of substances that food contact materials release into foods. Vegetable oil would be the most suitable food simulant for oils and fatty foods, but it is difficult to remove by heating due to its high boiling point, so heptane and 20％ ethanol are used as substitute food simulants in the test for plastics and rubbers. The EU has introduced an overall migration test into olive oil for plastics intended to come into contact with oils and fatty foods. This test method is described in European Standard EN1186-2. However, this method has several problems. Therefore, we improved the procedures for weighing samples in a desiccator containing 43％ sulfuric acid, extraction of the absorbed vegetable oil using the soaking method with an internal standard, methyl esterification of vegetable oil using sodium methoxide, and the GC conditions for the determination of vegetable oil. The improved method is simpler and much quicker than the original method, and the harmfulness of the reagents is reduced. It can be applied to both pla...
