Additive-free pectin-rich macromolecular films from citrus peel: Process-controlled composition, colloidal structure, and functional properties.
Citrus peel waste is a significant by-product of citrus processing with potential for recovering pectin-rich materials. This study developed additive-free, pectin-rich bioplastic films from citrus peel using integrated hydrothermal treatment (HT) and microfiltration (MF). A 23 full factorial design was employed to inve...
