1. Once Opened

Commonly, bulk shelled peanuts can be only used after one month since the opened date. Once the outside air gets to them, oxidation will start its work within just weeks. 

Make a mental note of this if you hate the idea of throwing away expired nuts over and over.

2. In The Shell

In other words, get some can, and your favorite snacks will stay delicious and ready to fill your belly for 4 months straight.

3. After Expiration Date

After the expiration date, they can be last for two years when frozen or twelve months when refrigerated.

4. Unopened canned or bottled Peanuts

When sealed in a can or bottle, the shelf life of peanuts may go up to two years, even at room temperature, four years in the refrigerator, and, surprisingly, forever in the freezer.

5. In the freezer

Bulk raw peanuts in shell can last almost permanently when frozen. Meanwhile, shelled peanuts need to be blanched and unsalted to achieve the same lifespan in the freezer.

6. In the fridge

Should you refrigerate nuts, they will last longer than normal. For instance, bulk peanuts in shell will last as long as nine months in the fridge.

Still, shelled ones will expire after one-third of that time in the same condition.

6. Boiled peanuts

How long are boiled peanuts good for depending on how you store them. If you freeze boiled ones, you can keep them for several months, but the taste and texture will gradually deteriorate. But if we are talking about room temperature, these cooked can only stay for two or three days. After that, oxidation kicks in.

7. Honey roasted peanuts

Honey roasted peanuts are consumable for about three months if kept adequately at room temperature. Double that time for fridge condition.

How To Tell That My Peanuts Have Gone Bad? 

Can it go bad? Unfortunately, yes! Because of the high content of oil, they may go rancid if you do not preserve them correctly.

Know that they will be bad for you if they show one of the following signs:

- They smell sour (similar to the odor of sour milk).

- They taste bitter or sour instead of nutty.

- The nuts are covered with mold (black, white, or green spots on the surface) or become discolored.

- They feel shriveled rather than solid in your hand.

How To Preserve Peanuts 

If you want to keep them fresh but do not intend to store them until the next season, you had better keep them in a cool, dry, well-ventilated yet dark place.

Notwithstanding, if you want to preserve them for a much longer time, put them in the fridge or freezer.

However, only unshelled ones can maintain their quality and texture permanently without any specific storage method.
