Mucilage-based composites films and coatings for food packaging application: A review.

Developing sustainable and eco-friendly packaging solutions has garnered significant interest in recent years. Mucilage-based coatings and composites offer a promising approach due to their biodegradability, renewable nature, and ability to enhance food quality protection. This review paper discusses the impact of mucilage-based composites and coatings on various packaging applications, focusing on their physical, mechanical, morphological, barrier, and functional properties. These materials' adaptability, flexibility, transparency, and compatibility with various food products make them highly suitable for food packaging. The morphological structure of mucilage-based films contributes to improved adhesion, surface roughness, and homogeneity. Enhanced barriers against moisture, oxygen, and other gases extend the shelf life of packaged food while maintaining its quality. Mucilage from different plant sources exhibits functional properties such as antioxidant and antimicrobial activities, which enhance food preservation. These attributes and mucilage's biocompatibility and biodegradability align with the growing demand for environmentally friendly packaging options. The review also addresses cost-effectiveness, regulatory compliance, consumer acceptance, recycling infrastructure compatibility, supply chain considerations, and the need for ongoing innovation. Future advancements in mucilage-based packaging will depend on optimizing performance, scalability, and sustainability. By understanding the effects on physio-mechanical, morphological, barrier, and functional attributes, mucilage-based composites and coatings hold great potential for advancing sustainable food packaging solutions.
