环境友好型复合纳米材料在食品包装中的应用

目的综述环保纳米包装材料的最新进展,为食品包装行业提供理论指导。方法从活性包装、智能包装和生物基包装这3个方面进行阐述,再对其安全性进行分析。结果纳米材料因其独特的尺寸效应,优异的物理化学性能、生态性能和加工性能等,使之在包装领域,尤其是食品包装得到了广泛的关注与应用,但需重点关注其安全性问题。结论纳米材料能有效改善包装材料的性能,使包装材料智能化,虽然该研究尚处于起步阶段,但纳米技术在食品包装领域具有显著的发展前景。由于可参考的数据不够充分,纳米材料的毒性问题以及迁移到食品中的安全性等还需进一步研究。

Application of Environmentally Friendly Nanocomposites in Food Packaging

The work aims to summarize the latest advances in environmentally friendly nano-packaging materials to provide the theoretical instructions for the food packaging industry. The recent advances in food nano-packaging included active packaging, smart packaging and bio-based packaging. Finally, the safety of such materials was analyzed. Due to the unique size effect of nano-materials, it exhibited excellent physical and chemical properties, ecological performance and processing performance in the packaging fields, especially food packaging. As a result, it attracted a wide range of attentions and applications. However, close attention should be paid to the safety issues. The nano-materials could effectively improve the performance and intelligentize of the packaging materials. Although still in its infancy, it was believed that the nanotechnology in the field of food packaging was to be significantly prospective. Because the reference data are not enough, the toxicity of nanomaterials and the safety of migration to food still need to be further researched.
