Expiration & Storage Tips
When does corn on the cob expire?
Unopened corn on the cob can stay fresh for 1-3 days in the refrigerator. The printed date on the package doesn't always apply to corn on the cob as it depends on when it was harvested. Once the corn has been cooked (boiled, roasted, etc), it will last for about 3 days in the refrigerator. If frozen, corn on the cob can last for up to 8 months.
How do you tell if corn on the cob is bad?
Check for a change in color. When fresh, the kernels should be a vibrant yellow. If the kernels seem dull or brown, the corn may be bad. You can also smell the corn. If it smells sour or off, it's likely spoiled. Lastly, you can use your finger to press down on a few kernels. If they're firm and burst under pressure, they're good. If they're squishy or dry, the corn may be bad.
Tips for storing corn on the cob to extend shelf life
• Keep the corn on the cob in the crisper drawer of your refrigerator. This will help maintain its freshness.
• If you've already cooked the corn, store it in an airtight container in the refrigerator
• You can extend the shelf life of corn on the cob by freezing it. To do this, blanch the corn first, then cut the kernels off the cob. Place the kernels in a freezer bag, remove as much air as possible, and then seal it. Store in the freezer.
• When you're ready to use frozen corn, just defrost it in your refrigerator. Remember, it's best to only defrost what you'll use.
