Application of Edible Films and Coatings in Food Production

Today, edible films and coatings can be used for a variety of purposes related to food products, singly or in conjunction with other compounds. There are many variations of edible film and coating, and all can be summarized in the following sentence. Edible films and coatings are thin protective, edible and biodegradable layers deposited on or wrapped around a food’s surface. Numerous usages of such films and coatings have been investigated, with reasonable success, one of which is active food packaging. Edible films and coatings are designed by blending edible raw materials with food grade additives. Biopolymers are naturally occurring polymers that are most important for the creation of edible films and coatings, including proteins, polysaccharides and lipids. In proper application, edible films and coatings make it possible to improve the physical characteristics of food products and enhance the distinctive tactile and visual attributes of their surfaces. In other words, edible films and coatings can aid in the function of active substance conveyance for such factors as antioxidants, antimicrobials, colors, and flavors. Protection of food products from oxidation, moisture absorption/desorption, microbial growth, and other chemical reactions is of the greatest importance. Through all these properties, edible films and coatings prolong the quality of food products and improve food safety.
