How will heat affect unopened cans of soup?

Unopened cans of soup are safe to eat if they have been exposed to heat, as long as the cans have not been damaged. The high temperature of the canning process kills any harmful bacteria that may be present in the soup, and the sealed can prevents any new bacteria from entering.

However, it is important to note that the quality of the soup may be affected if it is exposed to excessive heat. The soup may become discolored or have a different flavor, and the nutrients in the soup may be damaged.

If you are concerned about the quality of an unopened can of soup that has been exposed to heat, you should discard it.

Here are some tips for storing unopened cans of soup:

* Store cans of soup in a cool, dry place.

* Avoid exposing cans of soup to direct sunlight or high temperatures.

* If you do not plan to eat a can of soup within a few months, you can store it in the refrigerator.
