Does Corn Need To Be Refrigerated? Corn does not typically need to be refrigerated in order for it to be safe to eat.

This motion removes the heart and juice from each kernel. Whether youâre freezing corn on the cob or off, youâll get the best flavor if you use corn within two to six hours of picking. One bushel of corn on the cob yields 12 to 22 pints of whole-kernel or cream- style frozen corn. If youâre freezing in quart-size containers, youâll get roughly half that amount. Some people freeze corn on the cob in the husk, but that has no impact on flavor or keeping quality.
