ABSTRACT
To develop functional, sustainable and eco-friendly active packaging materials as alternatives to plastic films, we successfully prepared Ginkgo biloba leaf polysaccharide-stabilized selenium nanomaterials (Se-GBLP). Se-GBLP with glutathione peroxidase-like activity could efficiently remove harmful reactive oxygen species. As a functional additive, Se-GBLP was incorporated into degradable chitosan (CS) to fabricate CS/Se-GBLP films. The addition of Se-GBLP improved the mechanical properties, UV-visible light barrier performance, water vapor permeability, and antioxidant activity of the films. Preservation experiments demonstrated CS/Se-GBLP film could maintain quality and prolong the storage time of bananas and cherry tomatoes. It was the first time to use selenium-based nanozyme for fruit preservation. This work offered a cost-effective solution to reduce post-harvest losses, increasing sustainability and profitability. Future research should focus on more factors affecting freshness such as variety, maturity, harvest and storage conditions to improve preservation, as well as on the material's safety concern and environmental impact.
