摘　　要：研究4种紫外吸收剂,即2-(2’-羟基-3’,5’-二叔丁基苯基)-5-氯代苯并三唑(UV-327)、2-(2-羟基-5-甲基苯基)苯并三氮唑(UV-P)、2-羟基-4-甲氧基二苯甲酮(UV-9)和2-羟基-4-正辛氧基二苯甲酮(UV-531)在50、75℃和100℃3个温度条件下从食品包装牛皮纸迁移到固态食品模拟物Tenax~?中的迁移规律和影响因素。结果表明:随着温度的升高,紫外吸收剂的迁移速度加快,迁移量增加。此外,不同紫外吸收剂本身的物理化学性质(相对分子质量、油水分配系数等)也对其迁移规律和平衡迁移率产生了重要影响。在上述实验的基础上建立数学模型,以达到预测迁移量的目的。数据证明,所构建的模型可很好地预测在达到迁移平衡前,紫外吸收剂从牛皮纸迁移到Tenax~?中的迁移量。Migration of contaminants from packaging materials into food is a big issue in food safety and quality,as it may ose a threat for consumers.With that in mind,it is necessary to study migration characteristics and mathematic modeling o predict the amount of migration.In this study,the migration of four kinds of ultraviolet absorbers(UV-327,UV-P,UV-9nd UV-531)from kraft paper to solid food simulants was investigated at50,75and100℃.Effects of temperature and hysicochemical properties of the ultraviolet absorbers on migration were examined.Temperature played a key role in the igration process.The migration rate and final migration amount increased with temperature.Smaller molecular weight,lower values of lgPo/w and boiling points of migrants had a positive impact on the migration.The mathematic model based n Fick's second law was built and applied to predict the migration amount of UV-P from paper into solid simulants at70℃.he results showed that the built mathematic model could predict the migration amount very well in the initial period before quilibrium.
