chemistry professor from mainz university developed in a collaborative research project a novel foil packaging material that displays information on food freshness by means of color changesthe mainz chemistry professor katja heinze and her luxembourg cooperation partner dr. patrick choquet have received the interregional research award for the development of novel, intelligent foils for food packaging. this is the sixth time this award worth eur 35,000 has been presented. its purpose is to promote collaboration in crossborder research projects and reinforce the profile of the interregional research landscape. "to offer capable partners the best conditions for crossborder cooperation that is the main aim of our mutual cooperation strategy in the sector of higher education and research in the greater region. the surfamine research project that has been honored with the 2014 interregional research award is an outstanding example of the potential that lies in crossborder cooperation," emphasized state secretary professor thomas deufel of the ministry of education, science, continuing education, and culture of rhinelandpalatinate.working in collaboration with dr. patrick choquet from the centre de recherche public in belvaux, luxembourg on the surfamine project, the work group of professor katja heinze of the institute of inorganic chemistry and analytical chemistry of johannes gutenberg university mainz jgu has developed innovative foils for foodstuff packaging. "in view of the series of food scandals that have occurred in recent years, there is an increased interest in monitoring food freshness and in food safety," heinze explained the background to the research project. the aim of the threeyear surfamine project was to develop a form of food packaging that would display realtime information on the status of the packaged items. the idea was to create an intelligent foil that would interact with the atmosphere within the package and display information about its composition by means of colorimetric signals in the form of a change of color from green to red, for example.
