Can You Freeze Corn Kernels?
Yes, you can freeze it.
10-12 months
Corn is worth freezing close to the moment it's cut, since its sugars start converting to starch within hours of exposure to air even before any real spoilage risk sets in — corn frozen the same day it's shucked keeps noticeably more of its natural sweetness than corn that sat in the fridge for a day or two first. The quick blanch this site recommends before freezing does more than preserve color; it also halts that sugar-to-starch conversion in its tracks, locking in sweetness that would otherwise keep fading even in the freezer. Frozen corn can go straight into a soup, salad, or sauté without thawing, since the kernels are small enough to cook through quickly from frozen.
Corn cut fresh off the cob at home, rather than a store-bought bag that's already been frozen, benefits the most from being frozen the same day it's shucked — the sugar-to-starch conversion that dulls corn's sweetness keeps progressing in the fridge even if it doesn't spoil outright within a day or two, so a delay before freezing costs real flavor even when it doesn't cost food safety.
Corn purchased still in the husk and shucked at home right before freezing retains more sweetness than corn bought pre-shucked and cut, since the husk itself slows that sugar-to-starch conversion somewhat compared to kernels that have already been fully exposed to air at the point of sale.
