淀粉/聚乙烯醇基抗菌包装薄膜的研究应用进展

Progress in Research and Application of Antibacterial Packaging Film Based on Starch/Polyvinyl Alcohol

摘要:

淀粉/聚乙烯醇基抗菌包装薄膜具有较好的抗菌性和可生物降解性，是目前活性包装领域中的研究热点，但淀粉/聚乙烯醇基抗菌包装薄膜存在机械性能不足、耐水性差、抗菌剂迁移、环境适应性差等问题，从而限制了其在食品和药品中的应用。该文介绍了淀粉类型和聚乙烯醇的改性对抗菌包装薄膜综合性能影响的研究进展；阐述了抗菌包装薄膜中抗菌活性成分的控释机理与方法，以及淀粉/聚乙烯醇基抗菌包装薄膜在果蔬和肉制品贮藏保鲜中的应用情况。智能化活性包装材料有着广阔的发展前景，未来多功能复合抗菌包装材料的研究将有助于提升抗菌包装薄膜的指示性、稳定性以及缓释调控等性能，有利于包装行业的可持续发展，为绿色包装材料在食药领域中的应用提供新策略。

Abstract:

The antibacterial packaging film based on starch and polyvinyl alcohol has good antibacterial and biodegradable properties, and has become a current research hotspot in the field of active packaging. However, it has some problems such as insufficient mechanical properties, poor water resistance, migration of antibacterial agents, and poor environmental adaptability, which limit its application in food and medicine. The research progress on the influence of starch type and polyvinyl alcohol modification on the comprehensive performance of antibacterial packaging films were introduced, and the controlled release mechanism and methods of antibacterial active ingredients in antibacterial packaging films and the application of antibacterial packaging film based on starch and polyvinyl alcohol in the storage and preservation of fruits, vegetables, and meat products were elaborated in this article. Intelligent active packaging materials have broad development prospects. In the future, research on multifunctional composite antibacterial packaging materials will help improve the indicative, stable, and slow-release control properties of antibacterial packaging films, which are conducive to the sustainable development of the packaging industry and provide new strategies for the application of green packaging materials in the food and pharmaceutical fields.
