How to store canned corn after opening?

In this brief guide we will address the question, “how to store canned corn after opening?” as well as other questions pertaining to the subject at hand like how to tell if your canned food has gone bad and what are the ideal storage practices for canned food. 

How to store canned corn after opening? 

The best way to store canned corn after opening is to change the container, and then either put it in the fridge or the freezer 

Whether you should put it in the fridge or the freezer is our question of interest here. The answer to this depends on how long you want to store it. 

Short term storage

Storing canned corn after opening for a short term means putting it in the refrigerator. The problem with canned food is that you NEED to change their container. Once the can is opened, the insides of it will rust because of the outside air. The brine solution in the can will aid in the oxidation process and your tin/can will go bad. Consequently, damaging the contents of your can, which is corn in our case. 

Opened corn when stored in a suitable container will last for about 3-4 days. The container chosen must be airtight and preferably glassware. Even if you choose a plastic one, make sure that you do not discard the brine solution that comes with it. Brine is a mixture of Sodium Chloride in water that acts as a natural preservative and does not react with the corn. 

Long term storage

Storing canned corn after opening for a long term means putting it in the freezer. The approach will remain the same. However, when you put it in the freezer, it is better to discard the brine that comes along with it. 

Since brine is out of play, the container chosen can now be a high duty freezer bag as well. What you need to make sure is properly drain all the solution before freezing the corn. Frozen corn will stay fresh for 1-2 months when stored in the freezer. 

The decision is all yours. I wouldn’t recommend using some of it and freezing the remainder everytime you purchase corn. It is better to first decide whether you will be using it within the next few days or not. Because once you go with freezing, there is no going back on refrigerating it. Liquids also expand when they freeze, therefore you need to be careful not to put canned corn in the freezer. 

How to thaw frozen corn? 

Thawing is an important step when it comes to corn. It is also important to note that thawed corn may not be as fresh as it was when you first opened the can. 

Do not take out the corn out of the container to thaw it. The best practice is to leave it overnight in the fridge. In this way, you will be able to keep it for 2-3 more days in the refrigerator. However, if you go with thawing it in the microwave or cold water, then the corn should be used immediately because it will definitely go bad. 

How to tell if canned corn has gone bad?

Usually, you can tell this by the presence of an off-odor in your corn. If the corn is soggy and smeels a bit off, it means that it has gone bad. There are some other problems with canned food as well that I’d like to discuss here. 

Look for holes/rust. 

If your canned corn has some holes or rust on the inner side when you open the lid, it means that the quality of corn has been compromised. Consuming such a food may negatively affect your health and you should toss it in the bin or return it to the shop owner if freshly bought. 

Mold growth

Because of the high moisture content inside the can, there are greater chances of mould and bacteria to grow. If you see any visible growth besides the food product, you should immediately discard the can. Visible growth means either the can was punctured or that you let it out in the open for too long after opening. 

Shrunken or inflated can

If the can is inflated or shrunken, it means that the integrity of the can was damaged during the handling or the distribution process. This affects the shelf life of the food product inside the can, and your product may expire even before the said “best by” date. You should not purchase a can that looks overly bloated or shrunken.

Improper sealing

Another common mistake is improper sealing. Note that the seal is where the lid of the can is present. An improper seal could be due to a malfunction in the machine that sealed it or due to poor handling practices during distribution. Remember that the seal is the weakest point of the can because it is supposed to be opened. If you notice the integrity of the seal compromised in any way, chances are that your food product is already spoiled, or will spoil before its “best by” date.
