Abstract:
To address the dual challenges of foodborne illness and plastic pollution, we present a sprayable, calyx-inspired food wrap engineered for safety and sustainability. Utilizing handheld electrospraying, zeolite-doped polycaprolactone forms a multi-scale network mimicking Physalis peruviana's protective structure. This polycaprolactone/chitosan/zeolite wrap provides a health-critical barrier, achieving >95% inhibition of tobacco mosaic virus and >92% antibacterial efficacy against pathogens such as Escherichia coli and Staphylococcus aureus. Additionally, it maintains high breathability (∼1500 g·m-2·day-1) to prevent food spoilage. Crucially, the wrap is non-toxic and fully biodegradable within 180 days, eliminating microplastic risks. In real-world validation, it extended the shelf life of perishable fruits by >7 days without quality loss, reducing food waste. Life cycle assessment confirmed an 84.97% reduction in CO2 emissions compared with conventional wraps, directly contributing to environmental health. This technology offers a scalable solution for sustainable nutrition security through a user-friendly application, enhanced food safety, and rapid environmental degradation.
