Edible Polysaccharide Films and Coatings

Regulating the mass transfer in food systems by edible films and coatings can increase food-product shelf life and food quality. Besides their barrier properties, edible films and coatings can act as carriers for functional food additives, antioxidants, antimicrobial agents and nutrients; and due to their biodegradability nature, could have an impact on overall packaging requirements. The objectives of this book are to review research on polysaccharide film-formation and characteristics, analyze mechanical and barrier properties of polysaccharide-based films, summarize applications of polysaccharide films in food products, and make conclusions as to the status of polysaccharide films and their future developmental direction.
