A High‐Efficiency Yet Sustainable Fresh‐Keeping Strategy Inspired by Calyx of Physalis peruviana

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 CO 2 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.
