Expiration & Storage Tips
When does corn flake cereal expire?
Unopened, broad guideline is that they’ll remain at best quality for about a year. Note, that the cereal won’t go bad after this date, but the quality may start to deteriorate. For opened packages, it's best to consume them within 1 month. If the cereal has been properly stored, they will remain safe to eat beyond the expiration date printed on the box. As for freezing, it's uncommon to freeze dry cereals, but if needed, they can be frozen in a tightly sealed airtight container for up to 3 months to extend its shelf life.
How do you tell if corn flake cereal is bad?
Cereal won't get moldy or spoil in a way that will make you sick unless it's kept in a very moist environment. However, it will start to taste stale when it's no longer fresh. So, if your corn flakes lack their usual crunch or are overly soft, or if they have an off smell or taste, it's best to toss them out.
Tips for storing corn flake cereal to extend shelf life
• Always store the cereal in a cool, dry place. Avoid exposing it to high temperatures or humidity.
• Once opened, reseal the bag inside the box tightly. For maximum freshness, you might want to consider transferring the cereal into an airtight container.
• Do not store the cereal near strong odours, like spices or onions, as cereals tend to absorb odors.
• Use the old-in-new-out (FIFO) principle when storing cereal to ensure you’re always making the most of your food’s shelf life.
