Scientists designed color-changing carbon dot biosensors that can detect spoiled meat in sealed packages in real-time, just in case you don't trust the sniff-test.

I've got a fairly reliable tool that does the same, I keep it in the middle of my face

Anosmia is more common than you might think. A lot of stuff that seems silly on the face of it is hella useful for people with disabilities.

Noses do seem silly on the face of anosmics.

[–] ebolapie@lemmy.world 1 points 5 hours ago (1 children)

I really walked into that one huh

[–] isVeryLoud@lemmy.ca 1 points 5 hours ago

Sure smells like it!

[–] Atlas_@lemmy.world 18 points 20 hours ago (1 children)

They're going to make this way too sensitive so people throw away even more food and effective prices get driven up. I guarantee it

[–] CovfefeKills@lemmy.world 4 points 11 hours ago

After they are legally mandated to use it because selling spoiled meat is profitable.

Cool cool.

leans forward

Now, can it also not persist in the environment for 1000 years after the thing it was packaging has been unpackaged?

I’ve had a number of occasions where I purchased meat and it was spoiled before the expiration date. At this point, I’m sick of putting my trust in big corporations and am trying to buy more foods produced locally.

[–] MedicPigBabySaver@lemmy.world 1 points 10 hours ago (1 children)

Where the hell are you buying meat? A friggin' flea market? BS.

[–] melfie@lemy.lol 1 points 10 hours ago

I was buying it at Kroger, but got tired of meat being expired the first day I got it home, long before the expiration date. Now I buy from a rancher down the road. Re-reading my comment, it may have been unclear that I’m buying local to get better quality than I can get from big corporations.

[–] Cethin@lemmy.zip 2 points 12 hours ago

No matter where you buy it, expiration dates are only a general guide, and more of a "date of manufacture" note than anything. We evolved to detect potential food that has gone bad. Trust your senses. Look and smell should be enough to know what's actually gone bad (which is usually past the "expiration" date). You can use something like this as a better guide for when food will actually go bad, but, again, trust your senses.

Won't that affect Walmarts profits? 🙃

[–] GR4CELESS@lemmy.zip 5 points 1 day ago (4 children)

Pictured is meat with Kirkland branding, which is Costco's in-house brand. Better place to shop than walmart already

Guy you can't say that! Won't you think of the poor CEO?

[–] Bluegrass_Addict@lemmy.ca 2 points 1 day ago (1 children)

options here are 1 corporation that owns a castle and got his balls tickled for decades long price fixing

and walmarts.... there is no good options to shop for food until they are removed from the planet

[–] FauxLiving@lemmy.world 2 points 1 day ago (1 children)

until they are removed from the planet

Where can I donate to your campaign?

The indicator turns into a "manager's special", no need to pay an employee to slap them on anymore

[–] devolution@lemmy.world 1 points 1 day ago

Gross. 🤣

[–] inb4_FoundTheVegan@lemmy.world 10 points 1 day ago* (last edited 1 day ago)

As a negative control, they also prepared an identical sealed tray containing only a wet sponge and the biosensor, but no meat. They observed that the biosensors in the pork and mutton trays turned bright yellow after 24 hours, while the one in the beef tray took 36 hours. In contrast, the control biosensor showed no detectable change.

That's so cool, meat is still gross, but this is unambiguously a fantastic thing for humanity. If it's actually used, I'd have to imagine the less reliable yet ass covering legal expiration date sticker will always be cheaper. Hope this becomes the new mandated standard, innovations are meaningless in the face of uncaring capitalism.
