Abstract: The development in the use of biomolecules capable of changing the food shelf life may facilitate to reduce the food waste challenge. Cassava starch/bovine gelatin/zinc oxide nanorod (n-ZnO) active bionanocomposite films were fabricated by incorporating saffron anthocyanin (SA) using a solvent casting technique. Their physicochemical properties such as, antioxidant, total phenolic content (TPC), thickness, and antibacterial activity, were investigated. Incorporating SA significantly (P<0.05) increased the film thickness from 0.06 mm to 0.14 mm. The introduction of the 2.5% SA into the biofilms also increased their antioxidant properties (DPPH radical scavenging) by more than 5 times. TPC of the cassava/gelatin films was improved by increasing the SA contents. Starch/gelatin/n-ZnO/SA films represented excellent antimicrobial behavior against S. aureus and E. coli . These characteristics suggest that saffron anthocyanin has good potential as a biofiller in composite films based on cassava starch/bovine gelatin/n-ZnO for active films in the food and pharmaceutical sciences.
