A smart milk carton helps prevent food waste by offering consumers and retailers a more precise expiration date.
Unfortunately, many people are prompted to throw out food if the date indicates it is expired—even though the item may still be safe to eat. To offer better expiration information, the University of Cornell’s Milk Quality Improvement Program developed a QR code and sensor that are incorporated into a smart carton. The code will contain data on the milk’s origins and processing, while the sensor will track the time the milk was packaged and storage temperatures. Both consumers and retailers can access the data via a smartphone.
