Abstract

Biopolymer-based food packaging films (FPFs) have emerged as promising sustainable substitutes for petroleum-derived materials, owing to their biodegradability, biocompatibility, and cost-effectiveness. However, their inherent limitations in physicochemical properties necessitate functional enhancements to meet stringent requirements for food preservation. This review systematically investigates the integration of photothermal (PTA), photodynamic (PDI), and photocatalytic (PCA) additives into biopolymer matrices, which synergistically confer light-activated antimicrobial activity, antioxidant effects, and structural reinforcement. We elucidate the underlying mechanisms, focusing on reactive oxygen species (ROS) generation and localized hyperthermia that disrupt microbial integrity. Key advancements include hybrid systems (e.g., PTA/PDI composites, sustained-release platforms, and multifunctional metal–organic frameworks [MOFs]) that achieve > 99% inhibition of pathogens. Material innovations—including curcumin-β-cyclodextrin complexes, polydopamine nanoparticles, and carbon nanotube hybrids—address critical challenges (e.g., photosensitizer hydrophobicity, nanoparticle aggregation) while enhancing mechanical strength, barrier properties, and controlled release. Photoactivated FPFs further exhibit dual functionality: enabling real-time freshness monitoring via pH-responsive indicators and delaying fruit senescence through ethylene degradation. Emerging strategies combining PDI, PCA, and PTA, alongside light-triggered gaseous antimicrobials, hold promise for next-generation smart packaging. Despite these progress, challenges persist: insufficient light penetration in complex food matrices, potential food quality degradation under prolonged/high-intensity irradiation, and oxygen dependence of ROS generation. Future research should target these limitations to enhance the practicality and safety of light-responsive packaging. This review provides a critical roadmap bridging material science and food technology, facilitating the development of eco-friendly, high-performance biopolymer films for ensuring food safety and extending shelf life.

光激活多模态抗菌生物聚合物薄膜：协同效应、创新和可持续智能食品包装

生物聚合物基食品包装膜（FPFs）由于其生物可降解性、生物相容性和成本效益，已成为石油衍生材料的有前途的可持续替代品。然而，它们在物理化学性质上的固有局限性需要增强功能以满足食品保存的严格要求。本文系统地研究了光热（PTA）、光动力（PDI）和光催化（PCA）添加剂在生物聚合物基质中的整合，这些添加剂协同赋予光活化的抗菌活性、抗氧化作用和结构增强。我们阐明了潜在的机制，重点是活性氧（ROS）的产生和局部热疗破坏微生物完整性。关键的进展包括混合系统（例如PTA/PDI复合材料、缓释平台和多功能金属有机框架[MOFs]），这些系统实现了99%的病原体抑制。材料创新——包括姜黄素-β-环糊精复合物、聚多巴胺纳米颗粒和碳纳米管杂交物——解决了关键挑战（例如，光敏剂疏水性、纳米颗粒聚集），同时增强了机械强度、屏障性能和控释。光活化FPFs进一步表现出双重功能：通过ph响应指标实现实时新鲜度监测，并通过乙烯降解延缓水果衰老。结合PDI、PCA和PTA的新兴战略，以及光触发的气体抗菌剂，为下一代智能包装带来了希望。尽管取得了这些进展，但挑战仍然存在：复杂食品基质的光穿透不足，长时间/高强度照射下潜在的食品质量退化，以及ROS生成的氧依赖性。未来的研究应该针对这些限制，以提高光响应封装的实用性和安全性。这一综述为材料科学和食品技术之间的桥梁提供了一个关键的路线图，促进了环保，高性能的生物聚合物薄膜的发展，以确保食品安全和延长保质期。

期刊介绍： Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field. The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest. Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials. Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
