Food wastage is a major concern for sustainable health and agriculture. To reduce food waste, classical preservation techniques such as drying, pasteurization, freeze-drying, fermentation, and microwave are available. Nonetheless, these techniques display shortcomings such as alteration of food and taste. Such shortcomings may be solved by active food packaging, which involves the incorporation of active agents into the packaging material. Recently, metal-organic frameworks, a class of porous hybrid supramolecular materials, have been developed as an active agent to extend food shelf life and maintain safety. Here, we review metal-organic frameworks in active packaging as oxygen scavengers, antimicrobials, moisture absorbers, and ethylene scavengers. We present methods of incorporation of metal-organic frameworks into packaging materials and their applications.
食物浪费是可持续健康与农业的一个主要问题。为减少食物浪费，有诸如干燥、巴氏杀菌、冷冻干燥、发酵和微波等传统保鲜技术。然而，这些技术存在诸如改变食物和口味等缺点。这些缺点可通过活性食品包装来解决，活性食品包装涉及将活性剂加入包装材料中。最近，金属有机框架，一类多孔杂化超分子材料，已被开发用作延长食品保质期和维持安全性的活性剂。在此，我们综述金属有机框架在活性包装中作为氧气清除剂、抗菌剂、吸湿剂和乙烯清除剂的应用。我们介绍将金属有机框架加入包装材料的方法及其应用。
