“I’ve read that undented canned food can last a decade or more.”
I’m just rotating-out some Campbell’s Chicken Noodle, Vegetable, Chicken Rice, Split Pea and Tomato Soups which have *2006* stamped on them - I’ve been *prepping* since 9-11 - and they’re just fine. Same with Saltines and Ritz Crackers. As long as the can isn’t dented, kept dry and cool, it’ll (probably) last longer than the mfgr’s dreaded expiration date. (Contents may settle in shipment and your mileage may vary.)
You haven’t noticed that the noodles in the chicken noodle soup get a little denser, less pleasant?
In my experience canned food lasts for many years, but that the ones with pasta in them don’t age well, they are totally safe, and eatable, but less palatable.
