BBQ sauce, ketchup, mustard, mayo, etc. are all bought non refrigerated, so why do they need to be refrigerated after they are opened?
In: Biology
None of the condiments ls you listed need to be refrigerated. Yes, even the mayonnaise. If it says refrigerate after opening on the package, it’s probably just the company being extra cautious.
When the product is packaged, it is prepared under a sterile environment, and sealed so that the inside of the packaging remains that way.
Once opened, the packaging is no longer sterile and bacteria/etc can enter the package and cause it to spoil
I always refrigerate bc that’s what the package says to do but restaurants don’t do it. The ketchup and whatnot are always on the table.
