The tl;dr - this is for 3D printed edible objects (think cookies) and varies the density of the infill so that it a QR code appears when the object is backlit by a strong light source.

Insanely clever idea. Doesn't change the ingredients, taste or outward appearance of the food, although it does introduce a pattern of hollow and solid spots in the food, so I'd guess it could effect texture in some way.

I'm not sure what the advantage would be over embossing the code on the exterior, though. It'd definitely make for a neat variation on fortune cookie.

That inside can’t be modified without damage the food, it’s for safety/tracking.

Darn it, I was thinking we would eventual subsist on a diet of nothing but edible QR codes.

Just in case you thought they were not putting enough crap in food already ...

But…this is already the food. The QR is made by the food itself.

May be true for the cookie in question, but how many other foods might not need some additional ingredient(s) to hold the shape. Or, a cookie inside some other food. Hard to think of any healthy foods this could be applicable to.

If you read the link you will notice that this method could be used only with 3D printed food, you print the QR with the food.

I would rather see more research in multi level bio farming.

Imagine if the forbidden fruit from the tree of knowledge had a QR code. Do you think it would link to a 5% coupon off my next Amazon purchase?
