The Ultimate Guide to Keep Corn Fresh
Corn is a sweet, versatile vegetable that enhances everything from barbecues to soups. However, its sugars convert to starch quickly, which can affect flavor and texture. Knowing how long corn lasts—and the best ways to store it—ensures you enjoy its peak sweetness and freshness.
Shelf Life of Corn
- At Room Temperature (Unshucked):
- Fresh Corn on the Cob: 1-2 days (best consumed immediately)
- In the Refrigerator:
- Unshucked Corn (in husk): 5-7 days
- Shucked Corn (wrapped or in an airtight container): 3-4 days
- In the Freezer (Blanched or Raw):
- Frozen Corn on the Cob: 8-12 months
- Frozen Corn Kernels: 10-12 months
Best Practices for Storing Corn
- Refrigerate Immediately – Store corn in the refrigerator with the husk on to retain moisture and sweetness for up to a week.
- Use Airtight Containers for Shucked Corn – If the corn is shucked, wrap it in plastic or place it in an airtight container to preserve freshness.
- Freeze for Long-Term Use – Blanch corn on the cob for 4-6 minutes, cool in ice water, and freeze in airtight bags. Alternatively, freeze raw kernels for quick use.
- Avoid Room Temperature Storage – Fresh corn loses its sweetness rapidly at room temperature, so refrigerate as soon as possible.
- Keep Moisture in Check – Wrap corn in damp paper towels before refrigerating to prevent it from drying out.
Signs Corn Is Going Bad
- Dry or Shriveled Kernels – Indicates moisture loss and aging.
- Slimy or Moldy Husk – Mold or a slimy texture suggests the corn is spoiled.
- Unpleasant Odor – A sour or off smell signals spoilage.
- Discolored Kernels – Kernels turning brown or black should be discarded.
