Chitosan has a wide range of potential applications in different fields of chemical sciences, biological systems, food sciences and agricultural, pharmaceutical and medical industries. Recently, considerable research has been conducted to develop and apply bio-based polymers made from a variety of agricultural commodities and/or of food waste products. This increased interest was intensified due to concerns about limited natural resources of the fossil fuel reserve and the environmental impact caused by the use of nonbiodegradable plastic-based packaging materials. Such biopolymers include starches, cellulose derivatives, chitosan / chitin, gums, proteins (animal or plant-based) and lipids. These materials offer the possibility of obtaining thin films and coatings to cover fresh or processed foods to extend their shelf life.
