The film is integrated into the inside of the packaging, where it responds to biogenic amines, which are molecules produced when foods decay. The indicator dye in the sensor film reacts with the amines and changes its color. According to Dr. Anna Hezinger, a scientist at EMFT, &#8220;Once a certain concentration range is reached, the color change is clearly visible and assumes the task of warning the consumer. Unlike the expiration date, the information on the sensor film is not based on an estimate but on an actual control of the food itself.&#8221; The system is very inexpensive, meaning it could be used on a broad scale. The Fraunhofer team is also working on a measurement module with a built-in sensor film that could allow employees in the food and packaging industries to check the freshness of food products directly.
