Jaxon, not sure about your Kroger, but my local stores have ribs, pork loins & Boston butts that all say something like "enhanced with up to a 15% solution of blah blah blah", which is usually some type of salt water solution. Rummm may want to clarify this, but I think this may help with moisture retention as well as prolonging shelf life.
I have had ribs & pork loins from Kroger that have this label on them sit in the fridge for a 3-4 days with no ill effects.
My problem with them adding this solution is that I feel like I am losing 15% of the product in exchange for that amount of salt water. Feels like a bit of a ripoff, imho. This is why I usually stick to buying fresh pork and processing it for the freezer as soon as I get home or cooking within 24 hrs. If fresh pork is in cryovac packaging, I have never had a problem letting it sit for a couple of days in the fridge @ >40°, as long as it won't be past the sell-by date when I cook it.
