How Long Do Walnuts Last Heres What You Should Know

Walnuts are a delicious snack that is packed full of nutrients. They are rich in vitamin E, fiber, folate, magnesium, manganese, copper, phosphorus, potassium, zinc, omega 3 fatty acids, and protein. Walnuts are also low in calories and fat. They are also a good source of monounsaturated fats.

If you enjoy the concept of using walnuts in baked goods and other dishes, buying a large number of nuts and using them as needed is the way to go. However, consuming some and preserving the rest raises the question of how long walnuts will survive.

We’ve got you covered if you’re wondering how long you can securely store them. Here’s a step-by-step guide to their shelf life, how to store them properly, and how to spot the indications of deterioration.

What is the shelf life of walnuts?

Walnuts have a decent shelf life, lasting up to three months at room temperature with the shells on. When the shells are removed, the nuts oxidize considerably more quickly and only last a few weeks.

It’s not like you should throw out the entire batch after three months. However, at least a few of the nuts may appear to be dried up, rancid, or stale. If you have a batch with a best-by date on the label, give it a go. Food goods can sometimes last a bit longer than their expiration date. In a nutshell, the longer you keep walnuts, the more of them will be inedible when you open them. There comes a point when walnuts are no longer suitable for use in any recipe.

How to store walnuts to make them last longer

Walnuts, like the majority of other nuts, have a high-fat content. As a result, they can quickly get rancid and taste quite unpleasant. The trick is to correctly store the nuts by keeping them away from potentially harmful factors such as heat, air, and moisture.

Refrigeration is typically not required for walnuts that are still in their shells. To protect the shell from heating up, simply keep them out of direct sunshine. Place them in a dark corner of the pantry or kitchen, away from direct sunlight. Just break as many walnuts as you’ll need in the next several days.

Store walnuts in an airtight container away from heat sources such as radiators, ovens, microwaves, etc. It’s not like you should throw out the entire batch after three months.

Types of walnuts

Unshelled walnuts

Unshelled walnuts are available in grocery stores and health food stores. They are usually sold in packages of 25 pounds. Unshelled walnuts may be preserved for a surprising amount of time if kept out of direct sunlight.

In fact, when stored correctly, some of them can last up to 4-5 months before becoming unfit for eating. With minimal moisture, lots of circulation, and a low temperature, this is in excellent condition. However, air and bugs will always be able to permeate some shells. Even so, a few indications can readily distinguish them from the rest. They’re generally lighter in weight, have holes and some strange fuzz growing on them.

Shelled walnuts

When it comes to handling and storing shelled walnuts, extreme caution is required. When they are still in their original packaging and have not been opened, they can survive for quite some time – as long as the expiration date specifies.

Shelled walnuts are much easier to handle because there are fewer things to worry about. They come in bags of 50 pounds or 100 pounds. These are great for baking purposes since they don’t require shelling. Some people prefer shelled over unshelled walnuts because they feel less work is involved.

The problem with shelled walnuts is that they tend to spoil faster than unshucked ones. However, once they are exposed to oxygen, light, and humidity, they begin to deteriorate very rapidly. A single day without proper storage conditions could mean losing half of their value. Once the shell starts cracking, the nuts inside start drying out and become unusable. They will, however, have a short shelf life once opened because of the high-fat content, which is susceptible to spoiling. Even when stored correctly, walnuts can survive up to two weeks in the cupboard.

That’s why, after opening a store-bought pack of shelled walnuts, most people prefer to keep them in an airtight container.

Refrigerated walnuts have a long shelf life, up to a couple of months. Even yet, one or two of them may always appear to become disagreeable inside that duration. It only takes a little attention to check them before eating them raw or adding them to any recipes.

Do walnuts go bad?

Yes! The answer depends on how you choose to preserve your walnut supply. As mentioned earlier, refrigeration works well for preserving freshness.

But what happens when we put our walnuts into the fridge? Well, first off, let me tell you something: Walnuts do NOT need to be refrigerated. This is just another myth perpetuated by those who want to sell us stuff. Walnuts contain oil that, with time, becomes rancid, giving them a harsh flavor.

Walnuts may be kept fresh for a long time, but there comes a moment when they are no longer edible. This occurs when the storage conditions are unsuitable for walnuts, particularly in long-term storage. Warm storage temperatures, ventilation, and direct sunshine are all required.

How to tell if walnuts are bad

If you see moldy spots on your walnuts, throw them away immediately. Mold spores thrive at warm room temperatures and moist environments. If you find mold on your walnuts, discard them right away.

You should also avoid buying walnuts that look damaged or discolored. Discoloration usually indicates that the nut has gone stale. In addition, make sure that the package does not smell like rotten eggs. It might be difficult to tell whether certain walnuts have gone bad since they may not show any indications of spoilage right away. Walnuts can spoil in a variety of ways.

Shriveled and shrunken shells are the first indicator that the nuts aren’t safe to consume while still in their shells. A cracked shell increases the likelihood of a rotten nut within. You may spare yourself the trouble of opening these and simply throw them out, as 95% of nuts with shrunken shells are inedible.

If the outside appears to be in good condition, inspect the inside for evidence of mold or net formation. If that’s the case, make sure you get rid of the nuts right soon. However, one thing to keep in mind regarding walnuts is that even though the kernels and nuts look to be in good condition, they may still be inedible.

Conclusion

So now you know everything about walnuts. From where they come from to how long they last, it’s important to understand this food so you don’t waste money on inferior products. And remember, never buy anything unless you read the label carefully.

I hope all your food curiosities have been solved.
