I bought some fruit in Dole Fridge Pack off of shelf from store. It tasted surprisingly fresh. Is there a different method for fruit stored in shelf stable not refigerated plastic container vs fruit in cans. I though both were just different types of canning.

How do canned fruits stay fresh?
Canning is a high-heat process that makes the product sterile, and most canned fruit have added sugar to further help with the preservation process.
