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 changes
The 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 cross-border research projects and reinforce the profile of the interregional research landscape. "To offer capable partners the best conditions for cross-border 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 cross-border cooperation," emphasized State Secretary Professor Thomas Deufel of the Ministry of Education, Science, Continuing Education, and Culture of Rhineland-Palatinate.
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 three-year SURFAMINE project was to develop a form of food packaging that would display real-time 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.
In order to achieve this challenging objective, a number of institutes and commercial partners joined forces. In addition to Professor Katja Heinze's group at the Institute of Inorganic Chemistry and Analytical Chemistry of Mainz University, other project participants are the Department of Research and Material Analysis and the Department of Environmental and Agrarian Sciences of the Centre de Recherche Public – Gabriel Lippmann in Belvaux in Luxembourg, the Novelis Foil Innovation Center, also in Belvaux, and the ArcelorMittal Plasma Research Group in Liège in Belgium.
Working together in the SURFAMINE project, the teams have designed, synthesized, and employed novel dyes that are used to give the foils their color. These colors change on interaction with amines that are released when the packaged foodstuffs undergo bacterial decomposition and thus show how fresh the foodstuffs are.
In addition, a new and more environmentally-friendly coating process has been developed with which even large surfaces can be covered with the intelligent materials. The multinational cooperation project was financed by the Luxembourg Fonds National de la Recherche.
The Interregional Research Award is given to research networks that have at least a bilateral and preferably multilateral cross-border orientation in the Greater Region where France, Luxembourg, Belgium, and Germany meet. The project must be of cross-border interest in the Greater Region and the award is intended to pay tribute to new projects that strengthen public awareness and the attractiveness of the Greater Region.

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
