Exploring the Role of Phytochemical Additives in Enhancing the Properties of Gelatin-Chitosan Films: A Review

Phytochemical Additives in Gelatin/Chitosan

Abstract

The extensive use of plastic packaging has significantly contribute to the plastic pollution. To address this issue, there is an increasing demand for eco-friendly packaging solutions and researchers are exploring the use of biodegradable materials like gelatin and chitosan for food packaging. Adding plant phytochemicals to gelatin and chitosan films has garnered significant interest because of their phenolic content and antioxidant properties since studies on biodegradable films reveal that the mechanical properties, biodegradability, and antimicrobial activities of these films can be enhanced by adding phytochemicals. In this review, we focus on how different phytochemicals influence the antioxidant and antimicrobial activities of gelatin and chitosan-based biodegradable films and discussion on the possibilities of phyto chemical addition in these films.
