摘要: 研究250w和600w微波加热功率下微波纸中5种邻苯二甲酸酯向食品模拟物Tenax迁移的规律,并与常规高温迁移实验的结果比较。结果表明,微波加热条件下的迁移受加热功率、加热时间、迁移物分子结构、分子质量和极性等因素影响。与常规高温迁移相比,微波加热能加速物质迁移,说明迁移过程也受加热方式影响,微波加热可作为加速纸质包装中有害物质迁移的实验方法。

Abstract: The migration of five phthalates from microwave paper to food simulant Tenax was studied under microwave heating at heating power of 250 w and 600 w respectively. It was shown that the migration was influenced by microwave heating power, heating time, molecular structure, molecular weight and polarity of migrant. Compared with conventional heating, microwave heating could accelerate migration process, indicating that the migration was also influenced by heating mode. Microwave heating can be used as a unique method to accelerate the migration of the contaminants from paper packaging.
