Interpretive Summary: This chapter reviews research related to the application of nanoscience to food packaging. Studies performed by researchers around the world are summarized. Very small nanostructures (less than 100 nm in size) can be incorporated into food packaging to improve the quality and safety of the foods. They can also improve the strength and barrier properties of the packages to oxygen and water. In addition, nanosensors can be used in food packages to tell consumers whether food is fresh and safe or not.
Technical Abstract: A nanocomposite is a multiphase material derived from the combination of two or more components, including a matrix (continuous phase) and a discontinuous nano-dimensional phase with at least one nano-sized dimension (i.e. less than 100 nm). The main types of nanostructures are presented in this chapter according to their primary functions/applications in food packaging systems. Nano-phases frequently have a structural role, acting as reinforcements to improve mechanical properties of the matrix. They may also improve barrier properties in food packages. In addition they can provide “smart” or active properties such as antimicrobial activity, oxygen scavenging, and/or nanosensing. Nanosensors can provide information regarding the safety and/or stability of the product.
