Freezing Sweet Corn
Freezing is a quick and convenient way to preserve vegetables at home, and sweet corn is a popular, easy vegetable to freeze. If you have the freezer space, corn is an excellent vegetable to store frozen.
If you harvest corn, do it early in morning before it gets hot. Husk ears and remove silk, then bring six to eight quarts of water to a boil and submerge several ears at a time. Blanch the ears for four minutes. Cool promptly in ice water, drain and cut the kernels from the cob.
An electric knife is a handy tool for cutting off the kernels. Package the corn in freezer containers, leaving one-half inch headspace. Seal and freeze at 0° F or below for best quality.
Blanching, followed by chilling in ice water, are critical processes for producing quality frozen corn. The natural enzymes in corn need to be inactivated before freezing to prevent both loss of color and nutrients, and flavor and texture changes. These enzymes are inactivated by a hot blanch treatment. The chilling process prevents the corn from becoming mushy due to overcooking the starch.
