Expiration & Storage Tips
When does white cornmeal expire?
Unopened white cornmeal generally lasts for about 1 to 2 years from the printed date on the package if stored properly in a cool and dry area. However, if opened, it should be consumed within 6 to 12 months, depending on the storage conditions. If kept in the freezer, white cornmeal can last up to 2 years. But remember, the quality may degrade over time, even though it remains safe to eat.
How do you tell if white cornmeal is bad?
Specific signs that white cornmeal has gone bad include a stale or sour smell, change in color, presence of moisture or clumps, or any visible signs of mold. If any of these signs are present, I recommend you dispose of it immediately to avoid any health risks.
Tips for storing white cornmeal to extend shelf life
• White cornmeal should be stored in a cool, dark, and dry place to prolong its shelf life. The pantry is usually a good option for this.
• After opening, consider transferring the cornmeal to an airtight container. This helps prevent exposure to air and moisture, thus extending its shelf life.
• If you want to store it for a longer period, consider freezing it. Make sure the cornmeal is in a freezer-safe, airtight container or a heavy-duty freezer bag before placing it in the freezer.
• Always seal the package or container tightly after each use to maintain its freshness and prevent it from going rancid.
• Lastly, while your cornmeal might last beyond the best-by date on the package, always trust your senses. If it smells bad or shows signs of mold, it's safer to replace it.
