Polysaccharide-based edible films loaded with bioactive components for food applications: A review

Polysaccharide-based edible films have attracted increasing attention as sustainable food packaging alternatives in response to growing environmental concerns over plastic waste. These films are inherently biodegradable, and their functionality can be further enhanced through the incorporation of bioactive components, imparting antibacterial, antioxidant, and ultraviolet (UV) barrier properties. As a result, research on polysaccharide-based edible films has expanded rapidly in recent years. This review summarizes the latest advances in the field, with emphasis on polysaccharide materials, preparation techniques, and functional bioactive additives. The discussion addresses both the advantages and limitations of current strategies in practical applications, while also highlighting future directions for the development of bioactive polysaccharide-based edible films with improved performance and broader applicability.
