why does Parmesan cheese need to be in the fridge if it sits on the shelf in stores?
In: Other
If it’s a Parmesan wedge wrapped in plastic, the reason it won’t go bad is because they cut the wedge and wrapped it in a sterile environment. There’s also no air to touch it to make it go bad, and new bacteria isn’t getting in. I’ve also seen them put a small amount of liquid sometimes in with the plastic which would be a salty preservative.
Most of the time they’ll put them in the refrigerated section anyways though, to make them seem like a fresher product
Once you open it none of these things protect it anymore
