Minimum Integrated Functional Concentration (MIFC), unifying photocatalytic and antimicrobial modes in a GRAS-compliant LDPE/ZnO nanocomposite for active food packaging (opens in new tab)

The global problem of postharvest spoilage of fresh fruit is a significant issue, with the postharvest spoilage of perishable fruit due to microbial decay resulting in as much as 40% of total losses in developing parts of the world. One potential solution to this issue is active packaging; however, to date, a single-component integrated system with simultaneous visible light photocatalytic self-cleaning and dark-phase antimicrobial protection design has not been developed and independently te...
