The results indicate that pomelo peel can be used as a good film-forming substrate.Tea polyphenols have great potential when combined with pomelo peels to develop edible or biodegradable bioactive packaging films. PPF/TP composite films Containing 10% TP, it has antioxidant and antimicrobial properties, mechanical and water barrier properties of the combination are quite excellent.Improve creates stronger intermolecular bonds and a more compact microstructure. Can be used as an environmentally friendly alternative bioactive packaging material for oil products. More in-depth studies are being conducted to test the active potential of these films in food packaging systems.
