German meat product fresh scanner

Expired meat and meat products are a major hazard to food safety. At present, German researchers are developing a "fresh scanner", which is expected to eliminate the deterioration of meat on the market after its promotion.

In recent years, there have been many incidents of selling expired meat in Germany, and people are paying more and more attention to food safety issues. Generally, the quality inspection of meat and meat products on the market is not satisfactory, because the inspectors only judge the quality of the meat by smell and intuitiveness, and the frozen meat and cooked meat products are only based on the labels on the packaging. In response, researchers at the Technical University of Berlin and the Fraunhofer Institute for Reliability and Microelectronics Integration in Berlin are developing a test device called the “Fresh Scanner”. Researchers expect that with this device it will be possible to determine if the meat being tested has deteriorated within a few minutes.

The "fresh scanner" works on the principle that the chemical molecular structure of the surface of meat and meat products changes over time, and this change is unrecognizable to the naked eye. Through laser scanning and spectral analysis of the molecular structure, the portable scanner is used to scan the meat and meat products on the shelf to obtain relevant data. The scanner automatically compares the data with the standard data of fresh meat and meat products stored in the machine in advance. , it can show whether the meat being tested has deteriorated.
