Characterizations and antibacterial activities of passion fruit peel pectin/chitosan composite films incorporated leaf extract for preservation of purple eggplants.

The present study aimed to synthesize biodegradable films based on crosslinked passion fruit peel pectin/chitosan (P/CH) films incorporated with a bioactive extract from . leaf, and investigate their morphological, mechanical, water vapor permeability, optical, and antibacterial properties. The thickness and water vapor permeability of P/CH blend films were proportional to the increasing concentration of extract (PB).
