资源简介：
In this work, a facile and biomimetic strategy is introduced for food preservation at room temperature employing PLLA (poly(L-lactic acid)) or chitosan porous microspheres as gas “switches” or “stomata” in a shellac membrane to regulate O2, CO2, and H2O permeability and CO2/O2 selectivity. Surface coatings on fruits or packaging films prepared through this strategy show exceptional preservation performance on five selected model fruits with different respiratory metabolisms. These hybrid materials could effectively control the gases (O2, CO2, and H2O) permeability and CO2/O2 selectivity by adding different amounts of porous microspheres or depositing small functional molecules, which
demonstrate excellent antioxidant, antimicrobial, water-resistant, and reusable properties.
