I worked with a guy in the kitchen who would always burn the bread in the salamander. We were outside smoking one day and I asked him about it and he said he had no sense of smell. I thought it was strange to be a cook who couldn't smell, but then the whole not noticing bread burning made sense.

How much will food companies pay to get it to tell you that your food is bad early so you go shopping sooner?

Will it be able to tell the difference between blue cheese and rotting blue cheese?

You know what also has hundreds of millions of years of development in detecting what's gone bad, and costs you nothing?! Your actual nose! It's also almost certainly better than this product. Just smell your food. It'll tell you when something has gone bad. The date on it, or anything else, doesn't.

Useful for those whose noses were affected long term by COVID.

My wife and I would love something like this; she is anosmic and I am the dedicated suspicious food sniffer.

Also my own nose can, although that came free with my body. How much will this cost me?

Smell-o-vision, here we come!

Wondering if it also works on pathogens like Listeria or Clostridium botulinum, and if they have an idea to resolve the food matrix issues. Easily a million dollar industry only for food manufacturing alone, then.

Honestly, this is a really cool result. Since it’s a prototype I’m sure it’s wildly expensive right now, but eventually it’ll come down in cost that you can buy sensors like this for cheap. Rather than throwing stuff away once it’s past the expiration date, you now would wait for a positive sensor hit instead. Would really reduce food waste which is a huge problem.
