With the strengthening of the public awareness of food safety and environmental protection, functional food packaging materials have received widespread attention. Nanofibers are considered as promising packaging materials due to their unique one-dimensional structure (high aspect ratio, large specific surface area) and functional advantages. Electrospinning, as a commonly used simple and efficient method for preparing nanofibers, can obtain nanofibers with different structures such as aligned, core-shell, and porous structures by modifying the devices and adjusting the process parameters. The selection of raw materials and structural design of nanofibers can endow food packaging with different functions, including antimicrobial activity, antioxidation, ultraviolet protection, and response to pH. This paper aims to provide a comprehensive review of the application of electrospun nanofibers in functional food packaging. Advances in electrospinning technology and electrospun materials used for food packaging are introduced. Moreover, the progress and development prospects of electrospun nanofibers in functional food packaging are highlighted. Meanwhile, the application of functional packaging based on nanofibers in different foods is discussed in detail.
随着公众食品安全和环境保护意识的增强，功能性食品包装材料受到广泛关注。纳米纤维因其独特的一维结构（高长径比、大比表面积）和功能优势而被视为有前景的包装材料。静电纺丝作为一种常用的制备纳米纤维的简单高效方法，通过改进设备和调整工艺参数，可以获得具有不同结构（如排列、核壳和多孔结构）的纳米纤维。纳米纤维的原材料选择和结构设计可以赋予食品包装不同的功能，包括抗菌活性、抗氧化、紫外线防护和对pH的响应。本文旨在全面综述静电纺纳米纤维在功能性食品包装中的应用。介绍了静电纺丝技术以及用于食品包装的静电纺材料的进展。此外，还重点介绍了静电纺纳米纤维在功能性食品包装中的进展和发展前景。同时，详细讨论了基于纳米纤维的功能性包装在不同食品中的应用。
