Synthesis of Water Stable γ‐Cyclodextrin Metal–Organic Frameworks as a Carbon Dioxide‐Selective Layer for Preservation of Fresh‐Cut Pears by Modified Atmosphere Packaging (Small 42/2025)

Modified Atmosphere Packaging In article number 2411044, Hui Zhang and co-workers develop a three-layer composite film comprising a CO2-adsorbing inner layer of diphenyl carbonate-crosslinked γ-cyclodextrin metal–organic framework, a nanofiber intermediate layer, and a chitosan outer layer. This composite film achieves controlled atmosphere preservation of mangoes by regulating internal O2/CO2 ratios, effectively extending shelf life.
