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 fruits and vegetables typically have a longer shelf life than frozen fruits and vegetables, which should be used within six months of purchase. Freezing doesn't preserve food forever, it just slows down changes in color, texture and flavor, Blakeslee said.
