VTT sensor detecteert bederf voedingsmiddelen

VTT has developed a sensor that detects ethanol in the headspace of a food package. Ethanol is formed as a result of food spoilage. The sensor layer is part of a radio-frequency identification (RFID) tag, and the sensor data can be read wirelessly using an RFID reader in, for example, a smartphone. The sensor transmits information about the freshness of the food to the retailer or customer.
