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.
I use crumbled Saltines in my soups for a little added 'crunch texture', so the noodles aren't a focal point. Next can of CNS I open, I'll try wo/ Saltines, and see specifically how the pasta has held-up over time.
The rice and veg soups are just as tender, as when new, it seems to me. I have some various 5-yr old dumpling soups that I'm going to sample, now that you've mentioned this. If they're getting 'starchy', I'll rotate them out and get more consommé and broth varieties for replacements.
Thanks for the tip.
