Canned goods: Most expiration dates on foods in cans range from 1 to 4 yearsâbut keep the food in a cool, dark place and the cans undented and in good condition, and you can likely safely double that shelf life from 3 to up to 6 years. Frozen foods: Theyâre much like canned goods: pretty much expiration-proof.
Canned food has a shelf life of at least two years from the date of processing. Canned food retains its safety and nutritional value well beyond two years, but it may have some variation in quality, such as a change of color and texture. Canning is a high-heat process that renders the food commercially sterile.
