目的 为全面推进食品包装的功能化、智能化、绿色生态一体化发展,对纳米复合食品接触材料的发展现状进行深入的探究。方法 首先,概述纳米复合食品接触材料的多样性发展,并剖释纳米技术对食品接触材料的机械强度、气体阻隔、抗菌保鲜、活性智能监控和生物降解等性能的影响;紧接着,深入分析实际工况下(环境温度、接触时长、食物酸碱度等)食品接触材料中纳米物质的迁移行为规律;最后,纳米材料的毒理性作为食品接触材料安全评估的重点关注因素,还探讨纳米物质对人体细胞和组织器官等的潜在毒性。结论 现代纳米技术改善了柔性高分子聚合物的性能,实现纳米复合食品接触材料的多功能化,在肉类、面包、果蔬等食品包装中具有重要的应用前景,也为食品包装工业的发展提供重要的参考价值。

The work aims to conduct a more in-depth exploration on the current research of nano-composite food contact materials(NFCM),in order to promote the integrated development of food packaging in functional,intelligent and green ecological terms.The diversified development of NFCM was firstly summarized and the impact of nanotechnology on the mechanical strength,gas barrier,antibacterial preservation,intelligent activity monitoring and biodegradation properties of NFCM was outlined.Then,the migration behavior of nanomaterials from NFCM under actual working conditions(ambient temperature,contact time and food pH)was analyzed deeply.Finally,the potential toxicity of nanomaterials on human cells and tissue organs was explored,which was the key factor in the safety assessment of NFCM.Modern nanotechnology improves the performance of flexible polymer and realizes the multifunction of NFCM.This has broad application prospects in food packaging for meat,bread,fruits and vegetables,and also provides reference value for the development of food packaging industry.
