Two Fascinating Polysaccharides: Chitosan and Starch. Some Prominent Characterizations for Applying as Eco-Friendly Food Packaging and Pollutant Remover in Aqueous Medium. Progress in Recent Years: A Review
Summary
This review examines the properties of chitosan and starch—two biodegradable natural polymers—and their potential as eco-friendly replacements for petroleum-based plastic packaging. The authors summarize recent progress in improving these materials' strength, water resistance, and pollutant removal capabilities.
The call to use biodegradable, eco-friendly materials is urgent. The use of biopolymers as a replacement for the classic petroleum-based materials is increasing. Chitosan and starch have been widely studied with this purpose: to be part of this replacement. The importance of proper physical characterization of these biopolymers is essential for the intended application. This review focuses on characterizations of chitosan and starch, approximately from 2017 to date, in one of their most-used applications: food packaging for chitosan and as an adsorbent agent of pollutants in aqueous medium for starch.

Recent trends in the application of films and coatings based on starch, cellulose, chitin, chitosan, xanthan, gellan, pullulan, Arabic gum, alginate, pectin, and carrageenan in food packaging
This review covers the latest advances in using natural polysaccharides like starch, chitosan, and cellulose to create biodegradable food packaging as an alternative to petroleum-based plastics. Replacing conventional plastic packaging with these biopolymer-based materials could help reduce the generation of microplastics that contaminate food and ultimately enter the human body.
Chitosan with Natural Additives as a Potential Food Packaging
Researchers reviewed the potential of chitosan, a natural polymer derived from chitin, as a sustainable alternative to conventional plastic food packaging. Chitosan-based materials combined with natural additives show promising antimicrobial and biocompatible properties while being biodegradable. The study suggests these materials could help reduce plastic packaging waste and the associated microplastic pollution from food industry sources.
Research progress of biomass-based food packaging materials
This review examines biomass-based food packaging materials — including starch, cellulose, proteins, and chitosan — as renewable and biodegradable alternatives to petroleum-based packaging, discussing development strategies to address current shortcomings in environmental performance, food safety, and functional diversity in the context of growing global microplastic pollution from packaging.
