Abstract：
The utilization of biopolymer-based food packaging holds significant promise in aligning with sustainability goals and enhancing food safety by offering a renewable, biodegradable, and safer alternative to traditional synthetic polymers. However, these biopolymer-derived films often exhibit poor barrier and mechanical properties, potentially limiting their commercial viability. Desirable barrier properties, such as moisture and oxygen resistance, are critical for preserving and maintaining the quality of packaged food products. This review comprehensively explores different traditional and advance methodologies employed to access the barrier properties of edible films. Additionally, this review thoroughly examines various approaches aimed at enhancing the barrier properties of edible films, such as the fabrication of multilayer films, the selection of biopolymers for composite films, as well as the integration of plasticizers, crosslinkers, hydrophobic agents, and nanocomposites. Moreover, the influence of process conditions, such as preparation techniques, homogenization, drying conditions, and rheological behavior, on the barrier properties of edible films has been discussed. The review provides valuable insights and knowledge for researchers and industry professionals to advance the use of biopolymer-based packaging materials and contribute to a more sustainable and food-safe future.
摘要：
基于生物聚合物的食品包装的利用在符合可持续发展目标和提高食品安全方面具有重要的前景，可生物降解，和更安全的替代传统合成聚合物。然而,这些生物聚合物衍生的薄膜通常表现出较差的阻隔和机械性能，可能会限制他们的商业可行性。理想的阻隔性能，如耐湿性和抗氧性，对于保存和保持包装食品的质量至关重要。这篇综述全面探讨了用于获取可食用膜的阻隔性能的不同传统和先进方法。此外,这篇综述彻底审查了各种旨在增强可食用薄膜阻隔性能的方法，例如多层薄膜的制造，用于复合膜的生物聚合物的选择，以及增塑剂的整合，交联剂,疏水剂，和纳米复合材料。此外，工艺条件的影响，如准备技术，均质化，干燥条件,和流变行为，对可食性薄膜的阻隔性能进行了讨论。该评论为研究人员和行业专业人士提供了宝贵的见解和知识，以促进基于生物聚合物的包装材料的使用，并为更可持续和食品安全的未来做出贡献。
