Fluorochemical-treated paper was tested to determine the amount of migration that occurs into foods and food-simulating liquids and the characteristics of the migration. Migration characteristics of fluorochemicals from paper were examined in Miglyol, butter, water, vinegar, water-ethanol solutions, emulsions and pure oil containing small amounts of emulsifiers. Additionally, microwave popcorn and chocolate spread were used to investigate migration. Results indicate that fluorochemicals paper additives do migrate to food during actual package use. For example, we found that microwave popcorn contained 3.2 fluorochemical mg kg(-1) popcorn after popping and butter contained 0.1 mg kg(-1) after 40 days at 4 degrees C. Tests also indicate that common food-simulating liquids for migration testing and package material evaluation might not provide an accurate indication of the amount of fluorochemical that actually migrates to food. Tests show that oil containing small amounts of an emulsifier can significantly enhance migration of a fluorochemical from paper.
对经过含氟化合物处理的纸张进行了测试，以确定迁移到食品和食品模拟液中的迁移量以及迁移特性。在Miglyol、黄油、水、醋、水 - 乙醇溶液、乳液和含有少量乳化剂的纯油中，研究了含氟化合物从纸张中的迁移特性。此外，还使用了微波爆米花和巧克力酱来研究迁移情况。结果表明，在实际包装使用过程中，含氟化合物纸张添加剂确实会迁移到食品中。例如，我们发现爆米花爆好后，每千克微波爆米花中含有3.2毫克含氟化合物，在4摄氏度下放置40天后，黄油中每千克含有0.1毫克。测试还表明，用于迁移测试和包装材料评估的常见食品模拟液可能无法准确指示实际迁移到食品中的含氟化合物量。测试表明，含有少量乳化剂的油可以显著增强含氟化合物从纸张中的迁移。
