In order to solve the increasingly serious environmental problems caused by plastic-based packaging, carrageenan-based films are drawing much attentions in food packaging applications, due to low cost, biodegradability, compatibility, and film-forming property. The purpose of this article is to present a comprehensive review of recent developments in carrageenan-based films, including fabrication strategies, physical and chemical properties and novel food packaging applications. Carrageenan can be extracted from red algae mainly by hydrolysis, ultrasonic-assisted and microwave-assisted extraction, and the combination of multiple extraction methods will be future trends in carrageenan extraction methods. Carrageenan can form homogeneous film-forming solutions and fabricate films mainly by direct coating, solvent casting and electrospinning, and mechanism of film formation was discussed in detail. Due to the inherent limitations of the pure carrageenan film, physical and chemical properties of carrageenan films were enhanced by incorporation with other compounds. Therefore, carrageenan-based films can be widely used for extending the shelf life of food and monitoring the food freshness by inhibiting microbial growth, reducing moisture loss and the respiration, etc. This article will provide useful guidelines for further research on carrageenan-based films.
为了解决基于塑料的包装所造成的日益严重的环境问题，基于角叉菜胶的薄膜因其低成本、生物降解性、相容性和成膜性能，在食品包装应用中备受关注。本文的目的是全面综述基于角叉菜胶薄膜的最新进展，包括制备策略、物理和化学性质以及新型食品包装应用。角叉菜胶主要可通过水解、超声辅助和微波辅助提取从红藻中提取，多种提取方法的结合将是角叉菜胶提取方法的未来趋势。角叉菜胶可形成均匀的成膜溶液，主要通过直接涂布、溶剂浇铸和静电纺丝制备薄膜，并详细讨论了成膜机理。由于纯角叉菜胶薄膜存在固有局限性，通过与其他化合物复合来增强角叉菜胶薄膜的物理和化学性质。因此，基于角叉菜胶的薄膜可广泛用于延长食品保质期，并通过抑制微生物生长、减少水分损失和呼吸作用等方式监测食品新鲜度。本文将为基于角叉菜胶薄膜的进一步研究提供有用的指导。
