摘要

Food quality and safety are highly susceptible to environmental factors during storage and transportation. Conventional plastic packaging not only poses environmental challenges but often fails to stably maintain product quality or extend shelf life. In contrast, active and intelligent food packaging—incorporating functional materials that interact with food or its microenvironment—exhibits considerable potential. Polysaccharide-based bioaerogels (PBAs) are multifunctional materials characterized by high porosity, biocompatibility, biodegradability, and mechanical strength typically ranging from 0.3 to 3 MPa, which makes them highly suitable for food packaging applications. This study comprehensively reviews PBAs’ preparation methods, classification, and performance characteristics, emphasizes the significance of structure-property regulation, and explores their potential in active and intelligent food packaging. With the ability to effectively absorb excess moisture and gases as well as enable the controlled release of antimicrobial and antioxidant agents, PBAs contribute to monitoring food freshness and significantly extending shelf life. Despite their superior performance, challenges such as high production costs, technical complexity, and potential safety concerns must be addressed to meet industrial requirements. This review establishes a theoretical foundation for PBAs’ application in food packaging, advancing the development of more efficient and sustainable systems.
