摘要

壳聚糖/海藻酸盐基复合材料具有优异的机械性能、静电相互作用和可调节的屏障功能，在水果和蔬菜收获后的保鲜方面具有巨大的潜力。综述了壳聚糖/海藻酸盐复合材料的制备方法，包括层间自组装、交联剂介导成膜、混合后凝胶包衣和纳米复合膜。这些复合材料表现出显著的抗菌活性，这可归因于它们调节酶干扰、破坏静电破坏和促进离子性交联的能力。此外，它们的抗氧化功效来自活性氧清除和增强新鲜农产品中的内源性防御（酶和非酶）。此外，这篇综述解决了优化复合材料的挑战，并强调了可持续包装、智能输送系统和下一代采后管理的环保保存方面的进展。

Chitosan/alginate biocomposites for postharvest preservation of horticultural produce: A comprehensive review

Chitosan/alginate-based composites have demonstrated significant potential for preserving fruits and vegetables after harvest due to their superior mechanical properties, electrostatic interactions, and tunable barrier functionality. This review discusses various fabrication methods for chitosan/alginate composite systems, including layer-by-layer self-assembly, crosslinking agent-mediated film formation, post-blending gel coating, and nanocomposite films. These composite materials exhibit notable antimicrobial activity, which can be attributed to their ability to regulate enzymatic interference, disrupt electrostatic disruption, and facilitate ionotropic crosslinking. Additionally, their antioxidant efficacy arises from reactive oxygen species scavenging and enhances endogenous defenses (enzymes and non-enzymatic) in fresh produce. Furthermore, this review addresses the challenges of optimizing composites and highlights advancements in sustainable packaging, smart delivery systems, and eco-friendly preservation for next-generation postharvest management.
