Starch-based biocomposites reinforced with cellulose nanofibers from potato peel byproducts.

ABSTRACT: The valorization of potato peel byproducts, comprising approximately 14-40% of the total weight of fresh potatoes, through the extraction of cellulose nanofibers and their integration into starch-based biocomposites presents a sustainable strategy for enhancing the properties of biodegradable films for packaging applications. This study evaluated the physicochemical, barrier and mechanical properties of thermoplastic starch films incorporating cellulose nanofibers from potato peels (NCPP) at different concentrations (5%, 10%, and 15%). The addition of NCPP significantly increased the crystallinity index, with TPS-NCPP15 exhibiting the highest crystallinity (7.41%). Mechanical properties were significantly improved: Young's modulus increased from 1.31 ± 0.09 MPa in TPS to 7.54 ± 0.82 MPa in
