esults indicate that pomelo peel can be used as a good film-forming substrate. And tea polyphenols have great potential when combined with pomelo peels to develop edible or biodegradable packaging films. Overall, PPF/TP composite films Containing 10% TP, it has antioxidant and antimicrobial properties. The mechanical and water barrier properties of the combination are quite excellent. This is because it creates stronger intermolecular bonds and a more compact microstructure. This shows its potential to 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..
