Rotten meat doesn't stand a chance

. Things that come in direct contact with food products must also meet high standards. "Food safety is ensured by a barrier layer between the sensor film and the product itself. This barrier is only permeable to gaseous amines. The indicator chemicals cannot pass through," Hezinger explains.

Scientists are also working on a measurement module with a built-in sensor film. Employees in the food and packaging industries can use the module to test the freshness of food products directly. The device objectively analyses the color response while at the same time providing a more precise result than is possible with the human eye. This also permits an exact identification of intermediate shades of color. Dr. Anna Hezinger and her team are currently looking for partners in industry with which to further develop and produce the sensor film and measurement module.
