Which food can usually be stored longest on a cool pantry shelf?

Cans of soup are designed for long-term storage and can be kept safely on a cool pantry shelf for extended periods. This durability is achieved through the canning process, which involves sealing the food in a can and heating it to kill microorganisms, thus preventing spoilage. When stored in a cool, dry place, canned goods can last several years without degrading, making them an excellent choice for long-term storage.

In contrast, fresh fruits are perishable and typically have a much shorter shelf life, often requiring refrigeration or a timely consumption depending on the type. Packaged snacks may have a longer shelf life than fresh foods, but they are usually intended for a shorter duration compared to canned foods. Dairy products are highly perishable as well and usually require refrigeration; they cannot be effectively stored on a pantry shelf for long periods without spoiling.
