They create a QR code that will be on food | Digital Trends Spanish

A revolution in the application of QR codes Japanese researchers at the University of Osaka are doing, mainly on food so that, for example, people can see where the food or its ingredients come from.

The idea is a way to include an inconspicuous edible label embedded within the food, in his original experiments, cookies, that can be read without first having to destroy the food. Another important advantage of his method, known as «interior“is that the label does not change the external appearance or taste of the food at all.

The race is on to develop edible food labels that are non-toxic, don’t change the taste or appearance of food, and can be read without destroying the food itself. The Osaka University research team wanted to address all of these issues.

“Many foods can now be produced using 3D printers,” explains Yamato Miyatake, lead author of the study. “We realized that the inside of edible objects like cookies could be printed to contain patterns of empty spaces so that when a light is shined from behind the cookie, a QR code becomes visible and can be read with a cell phone”.

“Our 3D printing method is a great example of the digital transformation of food, which we hope will improve traceability and food safety,” says study lead author Kosuke Sato. “This technology can also be used to provide new food experiences through augmented reality, which is an exciting new field in the food industry.”
