Recent Advances in Biodegradable Films, Coatings and Their Applications

Biodegradable films have appeared as an alternative for synthetic plastics. These films have generated huge attention in recent years as they are beneficial over synthetic films. These films increase the shelf life of foods because they limit migration of moisture and gases. Biomaterials such as polysaccharides, proteins and lipids are generally chosen for the formation of biodegradable films. Functional properties of biodegradable films and coatings can be improved by adding compounds with antimicrobial and antioxidant properties. Biodegradable materials can be used in variety of food products such as dairy products, ready-to-eat meals, meat products, beverages, frozen products, dehydrated products and fruits and vegetables. Different protein-based biodegradable films from different plant sources such as soy, zein, wheat protein, peanut protein, cotton seed, pumpkin, sesame, pea, mung bean, castor bean, faba bean, kidney bean, casein, whey protein have been discussed in detail. Films prepared from cellulose, starch, pectin, and seaweeds have also been discussed.
