How are canned goods able to stay good for so long?

533 views

Just made myself a canned clam chowder, and really confused on why they’re able to stay good for so long.

I used to manage restaurants and it’s always confused me how my canned clams and clam juice, etc is fine sitting on a shelf for 6 months.

They’re not dehydrated, the can says to not add water. Ahh, please help lol
