Osaka University researchers have developed a novel way of embedding a QR code inside a cookie using 3D printing. Scientists claim that doing so won’t have any impact on the taste or outward appearance of the food.
This technology is known as “interiqr” (as in “interior QR”)
Data labels are commonly used in the food industry. These data labels can be as basic as stickers on fruit, or as technological as radio frequency identification tags.
Worldwide scientists are working on creating edible food tags that can be read without destroying the food itself. Moreover, these edible tags should be safe for consumption and shouldn’t alter the flavor or appearance of the food. This new study addressed each of these concerns.
Yamato Miyatake, lead author of the study said, “Many foods can now be produced using 3D printers,”
“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.”
Scientists foresee that it could prove to be a great alternative to frequently used wasteful and costly approaches such as paper labels or RFID tags applied to packaging.
“Our 3D printing method is a great example of the digital transformation of foods, which we hope will improve food traceability and safety,” said the senior author of the study, Kosuke Sato. “This technology can also be used to provide novel food experiences through augmented reality, which is an exciting new field in the food industry.”
