Cereal will stay crisp and fresh in an airtight container
We’re not sure who needs to hear this, but you do not need to refrigerate your cereal. Before you add milk to your breakfast, it’s easy to see that the flakes and the yummy goodness is extremely dry. That’s because it’s designed and made that way, and cereal companies use a process called toasting or drying to get these results.
One of the main reasons for this is because this process acts as a form of preservation. This means that cereal will keep in your pantry for weeks on end, and still remain fresh and crunchy. If you can, make sure you keep your cereal in an airtight container to avoid any traces of moisture.
