Abstract：
World hunger is getting worse, while one-third of food produced around the globe is wasted and never consumed. It is vital to reduce food waste to promote the sustainability of food systems, and improved food packaging solutions can augment this effort. The utilization of biomaterials in smart food packaging not only enhances food preservation and safety but also aligns with current demands for eco-friendly technologies to mitigate the impacts of climate change. This review provides a comprehensive overview of the developments in the field of food packaging based on the innovative use of biomaterials. It emphasizes the potential use of biomaterials derived from nature including cellulose, chitosan, keratin, etc. for this purpose. Various smart food packaging technologies such as active and intelligent packaging are discussed in detail including scavenging additives, colour-changing environment indicators, sensors, RFID tags, etc. The article also delves into the utilization of edible films and coatings, nanoparticle fillers and 2D materials in food packaging systems. Furthermore, it outlines the challenges and opportunities in this dynamic domain, emphasizing the ongoing need for research and innovation to shape the future of sustainable and smart food packaging solutions to enhance and monitor the shelf-life of food products.
摘要：
世界饥饿越来越严重，而全球生产的三分之一的食物被浪费掉了，永远不会被消费。减少食物浪费对促进食物系统的可持续性至关重要，和改进的食品包装解决方案可以加强这一努力。在智能食品包装中使用生物材料不仅提高了食品的保存和安全性，而且符合当前对生态友好型技术的需求，以减轻气候变化的影响。这篇综述全面概述了基于生物材料创新用途的食品包装领域的发展。它强调了来自自然界的生物材料的潜在用途，包括纤维素，壳聚糖,角蛋白,等。为此目的。详细讨论了各种智能食品包装技术，如活性和智能包装，包括清除添加剂，变色环境指示器，传感器,RFID标签,等。该文章还深入研究了可食用薄膜和涂层的利用，食品包装系统中的纳米颗粒填料和二维材料。此外，它概述了这个动态领域的挑战和机遇，强调持续需要研究和创新，以塑造可持续和智能食品包装解决方案的未来，以提高和监测食品的保质期。
