Does Corn Need To Be Refrigerated? Corn does not typically need to be refrigerated in order for it to be safe to eat. You will want to be aware of the fact that the longer you keep your corn in the refrigerator, the more flavor and vitamins you will lose, so it will not have quite as much nutritional value or taste to it.
Fresh corn will have firm, green husks with a pale brown tassel at the top. Sweet corn can be eaten both on or off the cob. The best thing to remember is NOT TO OVERCOOK it. If on the cob, shuck and clean the corn, bring your water to a boil, drop corn in, and cook for 2 to 4 minutes. Remove the corn from the water and serve quickly - donât let it stand in the water.
