Why did the caps turn black? Vaccum-sealed after 24 hours.

They’re just oxidized, they’re totally fine.
Side note, those steaks are fucking beautiful. Do NOT let those babies go to waste

Everyone knows about beef turning from red (oxymyoglobin) to brown (metmyoglobin) as it oxidizes but fewer know about the third deep purple oxidative state (deoxymyoglobin) which happens to the meat when not in the presence of oxygen. Usually you’d only see this on very freshly cut meat, before it’s been exposed to any oxygen. But all of the oxidative states of beef are actually reversible under the correct conditions and it seems your vacuum sealer pulled out enough oxygen to change it back to deoxymyoglobin.

Oxidation from contact with the plastic, 100% good to eat. Plus those look amazing!

It’s not really oxidation as stated by other folks, as much as it is deoxygenation from the vacuum pulling oxygen out of the meat. I would expect the black parts to turn red again once you open the bag. That spinalis is too perfect.

Are they half frozen?

Purple state from removal of oxygen. Very common in cryovac
