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.
Biocomposites and Poly(lactic acid) in Active Packaging: A Review of Current Research and Future Directions
This review examines how bio-based and biodegradable materials, especially polylactic acid (PLA), are being developed as sustainable alternatives for food packaging. While these materials aim to reduce petroleum-based plastic pollution, the review notes that biodegradable plastics can still break down into microplastics during their degradation process. Understanding the full lifecycle of these alternative materials is important for determining whether they truly reduce microplastic contamination.
