Nanocomposite Materials in Food Packaging: Opportunities, Challenges and Safety Assessment

Abstract

Nanotechnology by using nanocomposite is a promising future in food packaging applications in the global market. The capabilities of nanocomposite to improve mechanical, thermal, barrier and other properties has urged the researchers to explore more on this area. The common applications are used for food packaging such as active packaging, intelligent packaging, surface biocides, nanocoating, nano sensors, nutrition and nutraceuticals and bioplastics. However, the challenges occur when the unknown potential risks to human health is questioned by the society including ability of nanoparticles to migrate and the leaching mechanisms of nanoparticles leaching. This chapter discussed how nanocomposite plays an important role in food industry especially in food packaging. The opportunities, challenges and safety assessment were explained clearly to give overview to the reader the importance of nanotechnology.
