Migration of nanoparticles and degradation products from nanocomposite food contact materials

Project information

Nanocomposites have huge potential in food contact applications. As an example antimicrobial properties and enhancement of shelf-life for food can be obtained by incorporation of nanoparticles in the polymer packaging. Lately the release of silver nanoparticles from textiles has been demonstrated and the possible release of nanoparticles from the packaging to the environment or to packaged food is also a point of concern. In addition metal oxide nanoparticles are photocatalytic compounds and could influence the stability of polymers during photo-oxidation and radiation sterilization. The main objective of the project is to investigate nanocomposite food packaging materials and to determine whether and under what conditions nanoparticles migrate from the packaging to food stimulants and real foods. The project is financed by ÅForsk.
