Tastee Tape for burritos keeps them together, but what about those QR codes that some restaurants ask you to scan for their menus? Researchers from Osaka University have developed edible QR codes that you can eat after baking. Since the information is contained inside the food, the outer appearance of the cookie looks completely normal.
This technique is called “interiqr”, which refers to a novel three-dimensional (3D) printing method of embedding edible QR code in the interior of cookies. Once the edible QR codes are baked into cookies, the information can be revealed using a simple backlight from your smartphone, making for a nice appetizer if the restaurant or establishment should decide to do so. The researchers know that food tags and packaging contribute to a large source of waste worldwide, so embedding these tags into food should be able to greatly reduce this.

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