Nanotechnology in Food Packaging

Abstract

Nanotechnology promises many interesting changes for better life. Nanotechnology can be used to improve health, wealth, products and quality of life. Food nanopackaging is still a rather unexplored field of nanoscience and food science. Here I review developments in nano-packaging. This chapter describes first biobased food packaging for biodegradable packaging. Biobased packaging is indeed an alternative to conventional packaging with non-degradable plastic polymers that are a threat to the environment. Biobased packaging reduces waste, extend the shelf life, and enhance food quality. The next section discusses nanomaterials that improve packaging, such as better barrier properties, mechanical strength, flexibility and stability. Active packaging refers to the use of active materials such as antimicrobials and oxygen scavenging reagents. Smart packaging is the use of nanosensors and nanodevices that detect freshness or contaminants in foods or monitor changes in packaging conditions or integrity. The last section discusses safety issues and heath concerns of nanopackaging.
