| 中文摘要: |
| 目的 研究在不同迁移条件下， 食品用纸质包装中17种残留有机溶剂的迁移量。方法 制作污染试样， 在不同种类食品中迁移后， 测试其有机溶剂的迁移率， 同时比较迁移时间、 迁移温度、 食品特性、 微波辐照及超声振荡等因素对迁移率的影响， 绘制迁移率变化曲线。结果 迁移时间、 迁移温度、 食品特性、 微波辐照及超声振荡等因素都会影响残留苯系和其他有机溶剂的迁移率， 在较高的迁移温度下能在较短时间内达到较高的平衡迁移率， 100 ℃的迁移温度与25 ℃相比， 平均平衡迁移值提升了2.8倍（苯系溶剂）和2.3倍（其他溶剂）。食品特性对迁移率的影响由其极性和二者的相容性决定， 微波辐照和超声振荡会加速迁移过程。结论 食品用纸质包装中残留溶剂的迁移受多个迁移条件的综合影响， 其迁移规律对安全使用食品用纸质包装和维护食品安全具有重要价值。 |

| To investigate the migration of 17 residual organic solvents in food packaging paper under different migration conditions. Contaminated samples were prepared. The migration rate of residual solvents in different kinds of food was determined. At the same time, the influences of migration time, migration temperature, food properties, microwave irradiation and ultrasonic vibration on residual solvents migration were compared, and variation curves of migration rate were depicted. Migration time, migration temperature, food properties, microwave irradiation and ultrasonic oscillation all had influence on the migration rates of the residual benzene and other organic solvents. The equilibrium migration rate would reach a high level in a shorter time at a higher temperature. The equilibrium migration rate of benzene and other organic solvents at 100 ℃ was 2.8 and 2.3 times as high as those of 25 ℃. The effect of food properties was determined by their polarity and compatibility, while microwave irradiation and ultrasonic vibration could speed up the migration. The results showed that the migration rate of residual solvents was subjected to the comprehensive influences of multi-factors. Research on migration regularity in food packaging paper has a great value in its safe application and preserving food safety. |
