Do Raw Roasted and Boiled Peanuts Go Bad?
Yes, raw, roasted, and boiled peanuts can go bad. They can go bad in two ways. Here they are:
They can go rancid.
A lot of people love peanuts because of their heart-healthy fats. (*) However, these fats are also the exact reason why peanuts go rancid.
This occurs when you store the peanuts for too long in a suboptimal environment.
When the peanuts go rancid, they tend to have a harsh bitter taste. And while rancid peanuts are still safe for consumption, the sharp bitterness will not make eating the nuts more enjoyable.
They may go stale.
If your peanuts have been stored for a long time but haven’t developed that sharp bitter taste yet, there’s a high chance that they might have already gone stale.
Stale peanuts have altered taste and texture. It might be less tasty. Not only that, stale nuts have lost their trademark crunch and will have a softer texture.
Once again, stale nuts are safe to eat. However, you should process them (toast in a dry pan or baking in an oven) so they can get their crunch back.
How Long Do Peanuts Last? (Shelf Life Of All Types Of Peanuts)
Understanding peanut’s shelf life will allow you to identify how long your peanuts last so you can plan your purchase accordingly.
With that said, the peanuts’ shelf life depends on a lot of factors including:
Shelled or in- Shell,
In-shell peanuts last longer than shelled peanuts. This is because the shell protects the peanuts from air and sunlight which can make the nuts go rancid faster.
How it’s cooked or prepared,
Raw and roasted peanuts last longer than boiled peanuts because the latter is exposed to moisture and water.
Peanuts stored in the freezer or refrigerator last longer than the ones that are stored in the pantry or at room temperature.
And whether it’s still unopened or has already been opened.
Once you open the package, the nuts will be exposed to air, causing them to degrade faster. Because of this, unopened peanuts will last longer than opened peanuts.
To help you identify how long you can be able to enjoy your peanuts at their finest, we’ve prepared a table below:
|In-shell||4 months||12 months||2 years|
|Shelled||1 to 2 months||4 months||9 to 12 months|
|Boiled||2 to 3 days||5 to 7 days||2 to 3 months|
|Roasted (Unopened)||9 months||Not advised||Not advised|
|Roasted (Opened)||2 months||6 months||12 months|
|Honey Roasted||3 months||6 months||Not advised|
Please take note that all of these are just estimates. For safety purposes, make sure to inspect the peanuts for any signs of rancidity or spoilage before using or eating them.
How to Tell if Peanuts Have Gone Bad?
With that said, here are the warning signs that will tell you if the peanuts have already gone bad:
Change of Smell
The first thing you’d notice will be the change in smell. Originally, peanuts have a mild and subtle nutty, earthy, or woody smell. Once roasted, it will give off a scent that resembles that of coffee or chocolates.
If your peanuts give off a sour or chemical-like taste, it means that it has either gone stale or rancid.
The taste of peanuts depends on how they are cooked. Raw and boiled peanuts have a bland nutty taste while roasted peanuts have a sweeter flavor.
On the other hand, rancid peanuts will give off a sharp bitter flavor or a sour taste.
Good peanuts are hard and smooth. It becomes harder when roasted and softer and a bit wetter when boiled.
When it goes rancid or stale, the seeds will become dried and shriveled while the shell will lose its crunch.
While rancid and stale nuts are still safe for consumption, peanuts with mold on them aren’t. Once the peanuts have molds on them, throw them right away to avoid gastrointestinal issues.
Because of this, you should be on the lookout for any signs of discoloration. These may include green or black spots or white fuzzy growth on the peanut’s surface.
Insect or Pantry Bugs inside the Package
Another sign that your peanuts have already gone bad is when there are insects or pantry bugs inside the peanut’s package.
As of now, pantry pests are not linked to any diseases. However, the idea of consuming them is gross, so you should throw them right away. (*)
What’s the Right Way to Store Peanuts?
The recommended storage method varies depending on the type of peanuts you have. To help you out, we’ve shared some of the best storage practices for each type:
Since there’s still a shell that protects the nuts, its storage method is quite simple. You just need to place them in a well-ventilated and dry place.
Make sure that the storage place is free from moisture and humidity to prevent the growth of molds and bacteria.
Since these nuts already don’t have shells, you’d have to place them in an airtight bag or container before putting them in the pantry.
Another amazing option is to put the nuts in a glass jar, cover it with a towel, then place it in a pantry. Make sure to put this far away from light sources.
These nuts are already exposed to water, so they have the shortest shelf life. To make them last longer, you’d have to get rid of excess moisture. Here are some of the steps to follow when storing boiled nuts:
- Place the boiled nuts (if they’re still hot) under cold running water.
- Afterwards, transfer the peanuts to a towel to dry them completely.
- Place the dried peanuts in either an airtight container or a bag.
Roasted nuts are dried and cooked peanuts, so they last the longest. If you bought pre-roasted nuts from the grocery store, you just need to check out the storage instructions and follow the printed expiration date and you’re good to go.
But if you roasted your nuts, you’d have to let the nuts cool down first before transferring them into an airtight container.
Other Storage Tips to Keep in Mind
Here are some other storage tips that apply to all types of peanuts:
- If you won’t be able to finish the peanuts before their expected shelf life in the pantry, the best storage place for them would be the refrigerator. However, you need to place them in an airtight container and regularly monitor them for potential condensation.
- To achieve the longest possible shelf life, freezing peanuts is the way to go.
You’d also need to place them in an airtight and freezer-safe container. If possible, try wrapping the container with a layer of cling wrap for an added layer of protection.
- For optimum storage time, vacuum seal your peanuts instead of just placing them in airtight containers. This will ensure that the nuts are protected not just from moisture or freezer burns, but from oxygen as well.
