Bio-nanocomposites for Food Packaging: Synthesis and Surface Properties

Biomass-based packaging materials with various uses and functions are becoming increasingly innovative. Researchers and consumers have been paying significant attention to bio-nanocomposite packaging due to biomaterials' renewable, sustainable, biodegradable, and compatible characteristics. Therefore, there is a good chance that novel, high-performing, and environmentally friendly bio-nanocomposites will eventually replace conventional polymers made of petroleum that are not biodegradable. The demand for safer and more efficient food packaging systems worldwide has also raised interest in producing polymeric bio-nanocomposites for active and intelligent packaging applications. Current research trends in bio-nanocomposites, incorporating inorganic, organic, and nanohybrid nanomaterials, are thoroughly discussed. These materials are ideal for application in food packaging, given their superior mechanical, thermal, barrier, antibacterial, and antioxidant capabilities. The type of biomaterial, additives like nanoparticles, food type, storage conditions, and manufacturing process are some factors that can impact the quality of bio-nanocomposites. It has been discussed that the multifunctional qualities of bio-nanocomposite materials have little to no adverse environmental effects, and they may even enhance food safety and quality. The methods for creating polymeric bio-nanocomposites and their surface characteristics are the main topics of this chapter.
