A review of advancements in chitosan-essential oil composite films: Better and sustainable food preservation with biodegradable packaging
This review covers how films made from chitosan (a natural material from shellfish) combined with essential oils are being developed as biodegradable food packaging to replace conventional plastics. By reducing reliance on plastic packaging, these alternatives could help decrease the amount of microplastics that migrate into food and are ultimately consumed by people.
Sustainable biomaterials based on cellulose, chitin and chitosan composites - A review
Researchers reviewed advances in making sustainable composite materials from cellulose, chitin, and chitosan — abundant natural polymers found in plants and shellfish — as biodegradable alternatives to synthetic plastics that contribute to microplastic pollution. The review covers how these biopolymers can be dissolved and combined into fibers, films, and gels for a wide range of environmentally friendly applications.
An Antibacterial and Antioxidant Food Packaging Film Based on Amphiphilic Polypeptides‐Resveratrol‐Chitosan
Researchers developed a biodegradable food packaging film made from natural materials including chitosan and resveratrol that kills bacteria and prevents food spoilage. Unlike conventional plastic packaging that breaks down into microplastics, this film is made entirely from biological materials and poses no microplastic contamination risk. This type of eco-friendly alternative could help reduce the microplastics that enter the food supply through traditional plastic packaging.
Advancements in Chitosan–Anthocyanin Composite Films: Sustainable Food Preservation with Biodegradable Packaging
This review covers recent progress in developing biodegradable food packaging made from chitosan (derived from shellfish) combined with anthocyanins (plant pigments), which can preserve food freshness while avoiding the microplastic contamination associated with traditional plastic packaging. These films have antibacterial and antioxidant properties and can even change color to indicate food spoilage, offering a promising alternative to single-use plastics.
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.
Biodegradable Packaging Materials for Foods Preservation: Sources, Advantages, Limitations, and Future Perspectives
This review examines biodegradable packaging materials derived from natural sources as alternatives to conventional petroleum-based plastics for food preservation. Researchers found that materials made from polysaccharides, proteins, and lipids can effectively extend food shelf life while being more environmentally friendly.
