中文摘要:
      目的 辐照是食品行业中主要的消毒灭菌技术之一,通过系统综述国内外学者关于塑料食品包装材料辐照前后的变化,探究辐照技术对其物理化学性能的影响。方法 介绍食品辐照技术及其发展过程,重点分析辐照对常见塑料食品包装材料的辐解行为、迁移行为及物理性能的影响。结果 许多学者的研究都证明辐照会对塑料包装材料的光学、热学、力学性能及阻隔性等产生一定的影响,并导致降解产物的出现。结论 辐照对塑料食品包装材料的性能存在一定影响,需考虑材料辐照后在食品安全和物理性能方面的变化,且相关的法律法规尚有完善空间。
英文摘要:
      Irradiation is one of the main disinfection and sterilization technologies in the food industry. Through a systematic review of the changes of plastic food packaging materials before and after irradiation studied by domestic and foreign scholars, the influence of irradiation technology on their physical and chemical properties was explored. In order to do this, the irradiation technology on food and its development process was introduced. Particularly, the influence of radiation on radiolysis behavior, migration behavior and physical properties of plastic food packaging materials were the major focuses. Studies from many scholars have proved that there is a certain effect on the optical property, thermal, mechanical property and barrier performance of plastic packaging materials attributed by radiation, leading to the emergence of degradation products. Irradiation has a certain effect on the properties of plastic food packaging materials, so it is necessary to consider the changes in food safety and physical properties of materials after irradiation, and there is still room for improvement of relevant laws and regulations.
