食品包装新技术与食品安全

目的介绍近期食品包装技术所取得的新进展,以及新技术条件下的食品安全问题。方法分析新食品包装技术的工作原理及其在食品包装工业中的应用,包括智能包装技术、活性包装技术的工作原理及其在保持食品的品质、保障食品安全中所起到的作用。阐述新型环保材料,如可降解材料、可食性材料的工作机理及其在保护环境中所起到的作用。探讨在新技术条件下的食品安全问题,包括不同包装材料所含有的有害物质对食品安全的影响,以及包装材料由于外界环境的变化如加热、辐射等因素导致材料的变性而引发的食品安全问题。结果新技术、新材料的应用极大地丰富了食品包装的种类和功能,同时对环境保护也起到了积极的作用,但新材料也为食品安全带来一定的隐患,如有害物质的迁移。结论食品包装技术还需要加大研究力度,丰富包装的种类,保障包装食品的安全,降低有害物质的含量,提高包装产品的稳定性。

New Technologies in Food Packaging and Food Safety

Objective To introduce the recent development and innovation of food packaging and food safety problems under new technology conditions. Methods Working principles of new food packaging technology and its application in food industry were analyzed, including the function of intelligent packaging technology and active packaging technology in preserving food quality and guaranteeing food safety. The working principle of environmental protection material and edible materials and their functions of environment protection were described. And food safety problems under new technology condition including the effect of harmful substance in different packing materials on food safety, and the problems of material degeneration of packing materials due to environmental change like heating or radiation were discussed. Results With the application of new technologies and new materials, new types and functions of food packaging have been emerging and it also plays an active role in environment protection. However, the appearance of new food packing materials has caused some new problems of food safety like the migration of harmful substances. Conclusion More solid work needs to be done in the field of food packaging to diversify the types of packaging, guarantee food safety, reduce the harmful substances and improve the stability of the packed products.
