摘要

乙基纤维素(EC)是一种疏水性和可生物降解的聚合物,由于其可调节的性能和功能化合物,在可持续食品包装中获得了突出的地位。这篇综述系统地探讨了ec基复合薄膜的进展,强调通过聚合物共混和工艺创新来提高性能。通过将EC与亲水性生物聚合物(如魔芋葡甘露聚糖、明胶)和抗菌剂(植物多酚、精油、纳米银)混合,研究人员已经获得了具有优异机械强度、防潮性和活性保存能力的薄膜。静电纺丝和溶剂铸造等技术可以定制微结构,而结合ph敏感花青素或气体传感器的智能系统可以提供实时新鲜度监测。尽管在可扩展性和生物降解动力学方面存在挑战,但EC复合材料在平衡可持续性和功能性方面表现出卓越的多功能性。这项工作突出了EC作为下一代包装解决方案的基础材料的潜力,通过多功能设计解决食品安全,延长保质期和环境问题。

High-performance ethyl cellulose composite films: Innovations in functional enhancement for sustainable food packaging.

Ethyl cellulose (EC), a hydrophobic and biodegradable polymer, has gained prominence in sustainable food packaging due to its tunable properties and functional compounds. This review systematically explores advancements in EC-based composite films, emphasizing performance enhancement through polymer blending and processing innovations. By blending EC with hydrophilic biopolymers (e.g., konjac glucomannan, gelatin) and integrating antimicrobial agents (plant polyphenols, essential oils, silver nanoparticles), researchers have achieved films with superior mechanical strength, moisture resistance, and active preservation capabilities. Techniques such as electrospinning and solvent casting enable tailored microstructures, while smart systems incorporating pH-sensitive anthocyanins or gas sensors offer real-time freshness monitoring. Despite challenges in scalability and biodegradation kinetics, EC composites demonstrate exceptional versatility in balancing sustainability with functionality. This work highlights EC's potential as a cornerstone material for next-generation packaging solutions that address food safety, shelf-life extension, and environmental concerns through multifunctional design.

期刊介绍: Carbohydrate Polymers stands as a prominent journal in the glycoscience field, dedicated to exploring and harnessing the potential of polysaccharides with applications spanning bioenergy, bioplastics, biomaterials, biorefining, chemistry, drug delivery, food, health, nanotechnology, packaging, paper, pharmaceuticals, medicine, oil recovery, textiles, tissue engineering, wood, and various aspects of glycoscience. The journal emphasizes the central role of well-characterized carbohydrate polymers, highlighting their significance as the primary focus rather than a peripheral topic. Each paper must prominently feature at least one named carbohydrate polymer, evident in both citation and title, with a commitment to innovative research that advances scientific knowledge.
