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.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
