With the constantly escalating demand for safe food packaging, the utilization of biodegradable polysaccharide-based nanocomposite films is being explored as an alternative to traditional petrochemical polymer films (polyvinyl alcohol, polybutylene succinate, etc.). Polysaccharide-based films have excellent mechanical properties, water vapor transmission rates, and other physical characteristics. Films can fulfill numerous demands for fruit packaging in daily life. Additionally, they can be loaded with various types of non-toxic and non-biocidal materials such as bioactive substances and metal nanomaterials. These materials enhance bacterial inhibition and reduce oxidation in fruits while maintaining fundamental packaging functionality. The article discusses the design and preparation strategies of polysaccharide-based nanocomposite films and their application in fruit preservation. The types of films, the addition of materials, and their mechanisms of action are further discussed. In addition, this research is crucial for fruit preservation efforts and for the preparation of polysaccharide-based films in both scientific research and industrial applications.
随着对安全食品包装的需求不断升级，可生物降解的多糖基纳米复合薄膜的应用正在被探索，以替代传统的石化聚合物薄膜（聚乙烯醇、聚丁二酸丁二醇酯等）。基于多糖的薄膜具有优异的机械性能、水蒸气透过率和其他物理特性。薄膜能够满足日常生活中水果包装的众多需求。此外，它们可以负载各种无毒且无杀菌作用的材料，如生物活性物质和金属纳米材料。这些材料在保持基本包装功能的同时，增强了对细菌的抑制作用并减少了水果的氧化。本文讨论了多糖基纳米复合薄膜的设计和制备策略及其在水果保鲜中的应用。进一步探讨了薄膜的类型、材料的添加及其作用机制。此外，这项研究对于水果保鲜工作以及多糖基薄膜在科研和工业应用中的制备至关重要。
