摘　　要：随着消费者食品安全意识的增强,通过包装颜色变化对食品品质进行直观判断成为一个新的需求,智能包装近年来成为学界和产业界的共同关注点。pH敏感性材料与聚合物混合后获得的食品包装膜,在不同的pH条件下显示不同颜色,具有实时监测肉、虾、牛奶等食品新鲜程度的效果。本文介绍了化学显色剂和天然色素显色剂两大pH敏感性型指示器,分类介绍花青素、姜黄素、茜素、紫草素、甜菜碱等天然食品色素在不同pH下的变色机理,总结了pH敏感性材料与不同聚合物共混改性后在食品包装领域的研究进展、应用现状和研究趋势,为制备性能良好、绿色环保的智能食品包装提供参考。With the increasing awareness of food safety among consumers,the visual judgment of food quality through packaging color change has become a new demand,therefore,smart packaging has become a common concern of academia and industry in recent years.pH-sensitive materials mixed with different polymers to obtain food packaging films that display different colors under different pH conditions have the real-time monitoring of the freshness of meat,shrimp,milk and other foods effect.This paper introduces two major pH-sensitive indicators,chemical chromophores and natural pigment chromophores,and classifies the color change mechanism of natural food pigments such as anthocyanin,curcumin,alizarin,cometin and betaine at different pH values,and summarizes the research progress,application status and research trends of pH-sensitive materials modified by blending with different polymers in the field of food packaging,in order to prepare a good performance,green and environmentally friendly.It provides a reference for the preparation of good performance and green food packaging.
