The results obtained suggest that the pomelo peel, a typical agri- cultural by-product, can be used as good film-forming substrate, and tea polyphenol has a good potential to be incorporated into pomelo peel in developing edible/biodegradable bioactive packaging films with im- proved antioxidant and antimicrobial activity as well as mechanical and water-barrier properties. Overall, the PPF/TP composite films with 10% TP had relatively excellent combination properties due to the stronger intermolecular interactions and more compact microstructure, showing potential application as green alternative bioactive packaging materials for oil products. Further in-depth studies are now continuing to test the active potential of these films in more food packaging system
