Why does canned corn last longer?

Have you ever noticed that the can of corn in your pantry lasts longer than an ear of corn in your refrigerator? The reason is before the can corn is canned it is cooked and while it is still hot it is canned. The ear of corn is not cooked so therefore germs remain on it even in the cool environment of your refrigerator. This is why you need a Mini-Mate because the Activated Oxygen will make the ear of corn last longer.
