| 中文摘要: |
| 通过对当前聚乳酸(Polylactic Acid，PLA)基可生物降解薄膜在食品包装领域的最新研究进行总结，为解决传统石油基塑料难以降解、污染环境的问题，以及促进PLA基可生物降解食品包装膜的进一步发展提供指导和参考。介绍了PLA材料的特性、PLA基可生物降解薄膜的制备方法，重点对用于食品包装的PLA多糖基薄膜、PLA蛋白质基薄膜、PLA植物提取物和精油基薄膜、PLA纳米材料基薄膜以及PLA合成聚合物基薄膜的研究进行了综述。PLA基复合膜在保留可生物降解性的同时，具有良好的力学性能、物理特性以及生物活性，可有效延长贮存食品货架期。这些研究为开发兼具高性能和多功能的PLA基可生物降解薄膜提供了理论支撑，同时还为其实现大规模工业化生产指明了方向。 |
| 英文摘要: |
| The work aims to summarize the latest advancements in polylactic acid (PLA)-based biodegradable films for food packaging, to address the environmental challenges posed by non-degradable petroleum-based plastics and provide guidance for the further development of PLA-based biodegradable packaging materials. The characteristics of PLA materials and preparation methods of PLA-based biodegradable films for food packaging were introduced. The review specifically focuses on research progress in food packaging applications of PLA polysaccharide-based films, PLA protein-based films, PLA plant extracts and essential oils-based films, PLA nanomaterial-based films, and PLA synthetic polymer-based films. PLA-based composite films maintain biodegradability while demonstrating excellent mechanical properties, physical characteristics, and bioactivity, effectively extending the shelf life of packaged foods. These studies provide theoretical support for developing high-performance multifunctional PLA-based biodegradable films and indicate directions for achieving large-scale industrial production. |
