Welcome to r/science! This is a heavily moderated subreddit in order to keep the discussion on science. However, we recognize that many people want to discuss how they feel the research relates to their own personal lives, so to give people a space to do that, personal anecdotes are now allowed as responses to this comment. Any anecdotal comments elsewhere in the discussion will continue to be removed and our normal comment rules still apply to other comments.

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

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.

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.

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

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?
