Storing and Preserving Corn

Corn is a versatile and delicious vegetable that can be enjoyed in a variety of ways. However, it’s important to know how to store and preserve corn to ensure that it stays fresh and flavorful for as long as possible. Here are some methods for storing and preserving corn:


Freezing is one of the best ways to preserve corn. To freeze corn, start by shucking the corn and removing the silk. Blanch the ears of corn in boiling water for 4-5 minutes and then transfer them to an ice bath. Pat dry the corn and store it in airtight freezer bags or containers. Properly frozen corn can retain its quality for up to six to eight months.


Canning is another popular method for preserving corn. To can corn, start by shucking the corn and removing the silk. Cut the kernels off the cob and pack them into sterilized canning jars. Add boiling water to the jars, leaving 1 inch of headspace. Process the jars in a boiling water bath for 55 minutes for pints and 85 minutes for quarts.


Drying is a traditional method of preserving corn that can be done using a food dehydrator or in the oven. To dry corn, start by shucking the corn and removing the silk. Cut the kernels off the cob and spread them out in a single layer on a baking sheet or in the dehydrator trays. Dry the corn at 130-140°F until it is completely dry and brittle. Store the dried corn in an airtight container in a cool, dry place.

Risks and Considerations

Allergies and Intolerances

Corn is a common allergen and can cause an allergic reaction in some individuals. Symptoms of an allergic reaction to corn can range from mild to severe and can include hives, itching, swelling, difficulty breathing, and anaphylaxis. Individuals with a corn allergy should avoid all products containing corn, including corn syrup, cornstarch, and corn oil.

Corn can also cause digestive issues in some individuals. Corn contains a type of carbohydrate called fructans, which can be difficult for some people to digest. Those with irritable bowel syndrome (IBS) or a fructose intolerance may experience symptoms such as bloating, gas, and diarrhea after consuming corn.

GMO Concerns

Corn is one of the most commonly genetically modified crops in the world. GMO corn has been modified to resist pests and herbicides, and to increase crop yields. While the safety of GMOs is a controversial topic, the FDA has determined that GMO crops are safe for human consumption. However, some individuals may prefer to avoid GMOs for personal or ethical reasons.

It is important to note that not all corn is genetically modified. Organic corn and non-GMO corn are available and can be identified by labels on the packaging. Choosing organic or non-GMO corn can help individuals avoid potential health and environmental risks associated with GMOs.
