How Long Peanuts Last In Various Conditions

The shelf life of peanuts varies according to how and where they are stored. Here are some storage options and how long they can last in these conditions.

1. Unshelled Peanuts

Peanuts in their shell can last up to four months at room temperature. If you store them in the fridge, they will last for up to 1 year, and two years if stored in the freezer. When storing unshelled nuts, put them in an airtight container to avoid sucking in moisture, and extend shelf life.

2. Shelled Peanuts

If you remove peanuts from their shell, they will last for about one month; if you store them in a fridge, expect them to last for a year or two years in a freezer. If you wish to keep them, fresher, for longer, store them in an airtight container.

3. Bottled Or Canned Peanuts

When peanuts are put in a sealed can or bottle, their shelf life is extended. They can last for up to two years at room temperature, three to four years in the fridge, and eternity in the freezer. Canned peanuts remain fresh since moisture and fungus cannot get in.

4. Boiled Peanuts

Boiled peanuts can last for three days at room temperature since oxidation causes their taste and texture to deteriorate. If you freeze them, they can last for about three months, but we do not advocate storing them that long.

5. Roasted Peanuts

Roasted peanuts can last for three months past their expiration dates. If stored in a freezer, this time is extended by three more months. If your roasted nuts still feel fresh and nutty, they are probably suitable for consumption

6. Honey- Coated Peanuts

Honey-tossed nuts are tasty and long-lasting; they can last for three months when stored at room temperature in a sealed bag or container.  If stored in the fridge, they can last for six months.

How Do I Tell If Peanuts Have Gone Bad?

Now that you know how long a nut can last in various storage conditions, it is essential to know how to test for freshness. Sometimes, you find nuts in your pantry that have no expiry date, and you can’t recall when you got them. Here’s how to know if the nuts are still safe for consumption.

1. Smell

Due to high oil content, nuts do go bad, and they can be harmful to your health. Spoiled nuts have a sour odor that’s similar to curd or sour milk. If the nuts were in an airtight container, they’d likely have a gassy or paint-like smell.

2. Texture

Fresh nuts have a solid and hard texture. If nuts feel soggy or shriveled when touched, chances are they have gone bad. Soggy nuts have an unpleasant taste in your mouth and cause stomach irritation to some people.

3. The Appearance Of Mold On The Surface Of The Shell Or Nut

If you notice discoloration, black spots, or mold on your nuts, they have gone rancid. When you don’t notice any change in appearance or texture in peanuts, tasting is a sure way to tell if they have gone bad. Rancid peanuts have a repelling taste that is hard to miss.

How To Store Peanuts And Extend Their Shelf Life

Peanuts are best stored in a cool atmosphere away from moisture and other contaminants. Refrigerating these nuts is a great way to extend their shelf life by months. It is important to note that nuts absorb moisture from the surrounding environment, thus the need to keep them sealed up. Storing nuts properly ensures you eat fresh and healthy peanuts, save on food costs, and minimize wastage.

When storing nuts, please put them in an airtight glass container with a lid. This helps prevent odors from other food items from leaking in. You can also use a sealed plastic bag to store peanuts in the freezer.

If storing peanuts in your pantry, make sure they are away from sunlight, moisture, and foods with a strong aroma. When unshelled, peanuts can last in your pantry for a few months, but when shelled, they can last for a maximum of one month. If you want to store nuts for years and remain fresh and crunchy, freeze them in an airtight container below 0 degrees Celsius. You can thaw peanuts and refreeze them frequently without them losing their texture and flavor.
