Biopolymers and Bioplastics

Polymers play a crucial role in various applications, particularly in food packaging. However, conventional polymers are primarily derived from fossil fuels, raising significant environmental concerns. In response, extensive research has been conducted on the development of bio-based materials as sustainable alternatives. Several renewable resources can serve as sources for biopolymers, including polysaccharides such as pectin, cellulose, starch, gelatin, and alginate.

Recently, there has been growing interest in exploring chitosan as a biopolymer. While chitosan is recognized for its potential in food packaging applications, its antimicrobial properties and antioxidant activities remain limited and inconsistent.
