Traditionally, food packaging is used for improving food quality and providing consumers with descriptions of products. A new generation of intelligent ("smart") packaging materials is being developed to continuously monitor the properties of packaged foods and provide real-time information about their maturity, quality, and safety. In this paper, recent research in the development, properties, and applications of intelligent food packaging materials is summarized. Initially, we review the different sensing methods that can be used to detect alterations in food properties, such as those based on changes in time, temperature, humidity, oxygen levels, pH, chemical composition, or microbial contamination. The different approaches that can be used to design intelligent packaging materials are then highlighted, including films, bar codes, and labels. A number of applications of these packaging materials are then discussed to demonstrate their potential in the food industry. Finally, the challenges and future directions of food packaging are discussed.
传统上，食品包装用于改善食品质量并为消费者提供产品描述。新一代智能（“智能”）包装材料正在开发中，以持续监测包装食品的特性，并提供有关其成熟度、质量和安全性的实时信息。本文总结了智能食品包装材料的开发、性能和应用的最新研究。首先，我们回顾了可用于检测食品特性变化的不同传感方法，例如基于时间、温度、湿度、氧气水平、pH 值、化学成分或微生物污染变化的方法。然后突出显示了可用于设计智能包装材料的不同方法，包括薄膜、条形码和标签。然后讨论了这些包装材料的一些应用，以展示它们在食品工业中的潜力。最后，讨论了食品包装的挑战和未来方向。
