ABSTRACT
This chapter describes the functional food packaging materials based on biodegradable polymeric moiety, with biological activeness that can be suitable to use to their synthetic counterparts. In the present scenario of eco-preservation, the polymeric systems are under great interest such as polysaccharides; proteins; polyesters and polyhydroxy esters; and many more. In the food industry, many polysaccharides are discovered for food packaging applications because they are non-toxic, biodegradable, environmentally friendly, biocompatible, and eatable particles. Xanthan interacts with other components of food like whey protein. Additionally, wheat gluten, stored in wheat and maize, is another permissible protein with brilliant effectiveness, and it is a natural origin edible film and coating material. The descriptions of the biopolymers; applications of the most frequently researched natural polysaccharides such as starch, cellulose, chitosan; and proteins such as collagen, keratin, and whey protein, are given in this chapter.
