Waste Reduction embedded, 3D printed.
Would You Like a QR Code in That Cookie? By AlphaGalileo, October 19, 2022
Given that food tags and packaging are a large source of waste worldwide, this new method of embedding edible information into food also will be important for waste reduction.
A three-dimensional (3D) printing method developed by scientists at Japan's Osaka University can embed edible quick response (QR) codes inside food.
"Many foods can now be produced using 3D printers," explained Osaka University's Yamato Miyatake.
"We realized that the insides of edible objects such as cookies could be printed to contain patterns of empty spaces so that, when you shine a light from behind the cookie, a QR code becomes visible and can be read using a cellphone."
The "interiqr" technique produces a QR tag made from the cookie itself, keeping taste, flavor, and outward appearance intact.
