Do Peanuts Go Bad

Do Peanuts Go Bad

I provided information about how peanuts should be stored, as well as maximum peanut storage times, so that they do not spoil. You know you can only store your peanuts for so long in your refrigerator or freezer, as well as how to tell if they are going bad. It is a good idea to know how long peanuts last, how you can store them, and how to tell that they are gone bad, to avoid throwing away your favorite nuts and eating junk food. We have a few tips down below, but you might have to run a few experiments to find out how long you can make peanuts last.

How long your peanuts will last depends on what method of storage you chose, your storage conditions, if your peanuts are shelled or not, and a lot of other factors. When sealed in a jar or bottle, the shelf life of peanuts can reach two years, even at room temperature, four years in a refrigerator, and, surprising, eternally in the freezer. The only difference is in how long they last — peanuts that are still shelled are best stored at room temperature, and those that are not are worse.

As a general rule, you will want to keep your in-shell peanuts up to 4 months in your pantry, and as much as one whole year in your refrigerator. Both shell peanuts and In shell peanuts will last about twelve months if kept in the refrigerator, which is a pretty big jump up from the one to four months that they last when stored outdoors. If you would like to store your shelled peanuts for a longer period of time, you can place them in the freezer to preserve for as long as several months.

Peanuts can be stored for much longer by placing them in a fridge (4-6 months) or a freezer (1 year). After their expiration date, they may be stored two years if frozen, or twelve months when refrigerated. If you keep the peanuts from the moment they are purchased, their shelf life is extended up to one year if refrigerated, up to 2 years when frozen. When stored properly, you can expect that your peanuts, shelled or unshelled, can last for six months to two years when frozen.

Store shelled peanuts in an airtight container, or the original packaging, in your freezer for up to 12 months. Peanuts in the shell can be stored in the freezer and keep fresher when kept in the airtight containers. Even jars of peanuts that you bought at the grocery store that you did not open, will last forever if stored in the fridge, never spoiling.

In a freezer, peanuts retain their quality for a lot longer, but a lot of times, people do not have extra room in their homes to store peanuts. If you do want to store peanuts in the fridge, then you are advised to keep them in vacuum sealed containers as they are hygroscopic and if they are not stored correctly, they may absorb water from their surroundings, thus ruining the quality of them. Even if your peanuts can last up to several years if stored correctly, eventually they will become sour if they are not consumed.

Peanuts can be good for several months, but unless you consume them before they become rancid, you need to replace them. As you know by now, raw peanuts will not retain their quality long, especially if you keep them around at room temperature. As I have mentioned, roasted ones will not retain quality nearly as well as unshelled ones, so it is best to store them in a refrigerator.

Put your peanuts into a sealed bag and store them in the fridge; your roasted peanuts will last for up to 6 months. The cooler temperatures slow down the spoilage process, but your roasted peanuts should still be usable for 1 -2 weeks after being kept properly. Store raw peanuts in their shells in a cool, dry area, like the pantry, and you can keep them there up to 4 months. Raw peanuts should be stored in a cool, dry place, like the pantry, in an appropriately sealed, airtight container for up to 4 months.

When actually storing, it is best to seal the peanuts securely inside a freezer bag or an airtight container. If you open your bags, the best way to make sure they stay fresh is to immediately seal them up in a sealed container, in either the pantry or your refrigerator. If you are actually going to keep peanuts in your freezer, be sure that they are tightly sealed inside of a zipper-lock freezer bag, or in any freezer-safe, airtight container. Keeping your peanuts in a container is also likely to be a good idea if you are planning to store them outdoors, as this will help to keep animals and bugs away from the food.

Since even perfectly stored peanuts usually will not last longer than a year, limit your supply to only a few pounds at a time, so that you will not have to rotate out the supply too often. If you are toasting or flavoring your own peanuts, either do it on your own instead of buying them in bulk, or keep the processed nuts in a freezer to preserve the quality. Any non-plain peanuts — such as peanuts that have been roasted, dressed, or flavoring — should always be stored in a sealed container in your refrigerator or freezer, because the dressing may contribute to spoilage.

Unshelled peanuts can be stored in the refrigerator or freezer to prolong their shelf life; either put peanuts into sealed, airtight containers, or put their original packaging into heavy-duty, resealable freezer bags. You can also store unshelled peanuts in appropriately sealed glass jars covered inside with a cotton cloth.

You can also keep unshelled peanuts in your freezer, where they will last for around one or two years, when stored correctly in a plastic freezer bag or sealed in vacuum, but you will want to use your unshelled peanuts within the first year so you enjoy the best quality. While peanuts are fairly tough, they do not last longer than twelve months. Without the shell protecting the peanuts, it is very likely that these peanuts will start to significantly decrease in quality in just four weeks. While peanuts can last a long time, at a certain point, they will still start to deteriorate, showing certain telltale signs in their scent, texture, and flavor.

Can you eat peanuts after expiration date?

After opening, canned or bottled peanuts will keep in the refrigerator for about six months. It is possible to consume all the peanuts before the expiration date printed on the package. However, if you don’t see any signs of rancidity in peanuts, you can still consume them. It is not harmful to your health but does not taste good.

What happens if you eat expired peanuts?

If you eat expired peanuts, you may experience some digestive discomfort. The symptoms are usually mild and resolve within a few days. However, in some cases, expired peanuts can cause food poisoning. Symptoms of food poisoning include nausea, vomiting, diarrhea, and abdominal pain. If you experience any of these symptoms, you should seek medical attention.

Do roasted peanuts go bad?

To start, peanuts that have been properly roasted will have a deep brown color and a slightly nutty smell. If your peanuts have turned black or have developed mold, they have spoiled and should not be eaten.
