A comprehensive review of polysaccharide-based bionanocomposites for food packaging applications

Abstract The newly engineered functional systems of nanotechnology implemented in food packaging minimize product loss by extending shelf life. incorporation nanostructured materials into formulations enhanced the existing characteristics increasing specific surface area these biopolymers. Natural biopolymers were regarded as greener, more sustainable, and environmentally friendly materials. Starch nanocrystals have been employed effectively fillers polymer matrices to enhance mechanical moisture barrier characteristics. Both chitin chitosan nanoparticles biocompatible, biodegradable, inexpensive cost, mucoadhesive nature. Alginate demonstrated high thermal chemical stability. Because features, polysaccharide-based excellent candidates for nano reinforcements bio-nanocomposites. sized forms starch, chitin, chitosan, alginate are non-toxic antimicrobial. This study focused on current advances development films based nanoparticles, well trends challenges formulation bio-based polymers. review detailed synthesis using various techniques such hydrolysis, ionic gelation, reverse micellization, emulsification, crosslinking. type bio-nanocomposite is expected revolutionize entire industry.
