How Long Does Fresh Corn Stay Good?
Fresh corn is best eaten within 1 or 2 days, when the cobs are at their sweetest. Overtime, those natural sugars will convert to starch, and the kernels will lose their juiciness (a process called "respiration"). Cooler temperatures slow down that process, meaning unshucked, uncovered corn cobs can stay fresh for about a week.
You can freeze your own corn for up to 8 months, too. Remove the husks and silk, blanch for 4 minutes in boiling water, and plunge into ice water. Remove the kernels with a sharp knife. Freeze the kernels flat in large zip-top plastic freezer bags.
