Electrospun nanofibers with structural and functional advantages have drawn much attention due to their potential applications for active food packaging. The traditional role of food packaging is just storage containers for food products. The changes of retailing practice and consumer demand promote the development of active packaging to improve the safety, quality, and shelf life of the packaged foods. To develop the technique of electrospinning for active food packaging, electrospun nanofibers have been covalently or non-covalently functionalized for loading diverse bioactive compounds including antimicrobial agents, antioxidant agents, oxygen scavengers, carbon dioxide emitters, and ethylene scavengers. The aim of this review is to present a concise but comprehensive summary on the progress of electrospinning techniques for active food packaging. Emphasis is placed on the tunability of the electrospinning technique, which achieves the modification of fiber composition, orientation, and architecture. Efforts are also made to provide functionalized strategies of electrospun polymeric nanofibers for food packaging application. Furthermore, the existing limitations and prospects for developing electrospinning in food packaging area are discussed.
由于其在活性食品包装中的潜在应用，具有结构和功能优势的静电纺纳米纤维引起了广泛关注。传统的食品包装的作用仅仅是食品产品的储存容器。零售实践和消费者需求的变化促进了活性包装的发展，以提高包装食品的安全性、质量和保质期。为了将静电纺丝技术应用于活性食品包装，已经对静电纺纳米纤维进行了共价或非共价功能化，以负载包括抗菌剂、抗氧化剂、氧气清除剂、二氧化碳释放剂和乙烯清除剂在内的多种生物活性化合物。本文综述的目的是对活性食品包装用静电纺丝技术的进展进行简明而全面的总结。重点介绍了静电纺丝技术的可调变性，该技术可实现纤维组成、取向和结构的改性。还努力提供用于食品包装应用的静电纺丝聚合物纳米纤维的功能化策略。此外，还讨论了在食品包装领域开发静电纺丝技术的现有局限性和前景。
