Time and again, food contamination from materials such as plastics and glass leads to costly recall campaigns. The Fraunhofer Institutes IOSB and FHR develop multi-sensor concepts to detect contaminants in products. They will present these concepts along with the rest of their service range at the Anuga FoodTec in hall 4.2, booth D054/D058.
Fraunhofer FHR and its partner Fraunhofer IOSB will present the “FoodInSpector” sensor system designed for the quality control of food. FoodInSpector uses millimetre waves to scan products and detect contamination as well as deviations in the production process. The technology is capable of inspecting frozen products, baked goods, and hollow as well as filled products.
Millimetre wave sensors take their measurements based not only on the attenuation of the signal during the scan but also on the changes of the signal’s transit time caused by inclusions. Combined with an automatic image analysis process, the resulting system is able to reliably scan packaged goods for contaminants and detect deviations in homogenous production processes.
Furthermore, thanks to the ability to measure residual moisture, the system is particularly well suited for the monitoring of drying processes. Unlike x-ray technology, the processes can be applied directly without any additional radiation protection measures. They can also provide a stronger contrast ratio, particularly for plastic contaminants.
Up to now, the most common technique for product inspections in the food industry besides x-ray are optical systems such as hyperspectral cameras. For the most part, these systems only capture measurement readings on product surfaces. By combining them with high frequency sensors, it is possible to examine packaged goods and detect contaminations inside products.
Fraunhofer IOSB and FHR will demonstrate such a sensor system at the Anuga FoodTec using chocolate bars as an example. The process can be adapted to the most diverse products to deliver optimized customer-specific results, being especially suitable for dried and frozen food. System development is focused on the the ability to integrate these sensors into existing plants.
As one of Europe’s leading institutes, the Fraunhofer Institute for High Frequency Physics and Radar Techniques FHR conducts extensive research in the area of high frequency and radar technology. Its core research focuses on sensors for precise distance regulation and positioning as well as imaging systems. The applications range from systems for reconnaissance, surveillance, and protection to real-time capable sensors for traffic and navigation as well as quality assurance and non-destructive testing.
The Fraunhofer Institute of Optronics, System Technologies and Image Exploitation IOSB studies and develops multi-sensor systems and software that support humans in their perception of and their interactions with the environment. This ranges from the generation and automatic analysis of aerial and satellite images, e.g. of a disaster area, all the way to the sorting and quality inspection of bulk goods such as coffee beans or minerals.

Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.
The vacuum is not empty. It may sound like magic to laypeople but it has occupied physicists since the birth of quantum mechanics.
