When cashew nuts are purchased in bulk and stored properly, they can last for about a month at room temperature or up to 6 months in the refrigerator. Beyond that, it would be necessary to freeze. Most pre-packaged cashew nuts will have an expiration date, which will tell you how long you can leave the unopened package in your pantry. Cashew nuts last about 6 months at room temperature and more than 12 months in the fridge.
If you need even more time, you can freeze them. Cashew nuts have a long shelf life when stored under the right conditions. Storing them in a closet will keep them fresh for up to 6 months. But the best thing to do is store them in the freezer if you know you won't eat them quickly enough.
They can last more than a year in very cold temperatures. If you bought raw cashew nuts, they would last about a month in your pantry or up to six months in the refrigerator.
raw cashew nutspurchased in bulk can last up to 4 weeks in the pantry. If you want to keep it fresh longer, store the cashew nuts in the fridge.
Can last up to 6 months if stored this way. According to the University of California (UCAN), cashew nuts last about six months at room temperature and about 12 months in the refrigerator. It's similar to what I've seen on the labels of pre-packaged cashew nuts in supermarkets. When talking about shelf life, this means how long cashew nuts can last before they go rancid and lose their creamy flavor.
Actual shelf life will vary between manufacturers and sellers, but generally range from 6 to 12 months, unless placed in the freezer. If your cashew nuts give off an odor that reminds you of old paint or nail polish remover, it's a sure sign that they're ready. Even when you expose cashew nuts to extreme conditions such as sunlight, heat, and air, they can accelerate rancidity. It is a toxin that is not harmful in small amounts, but if you consume cashew nuts regularly, you could get hives.
For me, the default place for cashews (or walnuts, pine nuts, or pistachios) is a cupboard in the kitchen. That can add a little extra flavor to nuts, and who knows, you might also find an even tastier version of cashews. Freezing Cashew Nuts Reduces Chances of Mold Contamination and Prolongs Nuts Freshness. Therefore, you should assume that the cashew nuts you buy there might not retain their quality for half a full year at room temperature.
Of course, if you live in the tropics, where it's hot all year round, you also shouldn't assume that cashews will maintain quality for so long if you don't refrigerate them. Therefore, in damp locations, cashew nuts are more likely to grow mold unless you freeze or refrigerate them. As mentioned above, it is cashew nut seed that contains a healthy amount of good fats along with oil (like any other nut), which can go rancid at any time. Cashew nuts are a treat that is enjoyed as is, or they can add a special touch to foods such as curries, salads, desserts and homemade cakes.
If you are cutting the cashew nuts and you feel the knife slipping or the nut flaking gently, the cashew nuts have been spoiled. Cashew nuts usually come in well-designed containers that do an excellent job of keeping moisture out, so if the nuts are still in their original sealed packaging, freeze them as they are. So, while rancid cashews aren't necessarily unsafe to eat, they taste pretty bad and what I recommend is to discard them. These dates are mostly accurate, and if you store your cashews properly, you can not only enjoy these nuts until that date, but probably for a month after.
Finally, if your cashew nuts have started to wilt and become very dark in color, they have gone from being better and are no longer suitable for consumption. .
