Store shelled or shelled walnuts safely in an airtight container and store them in a cool, dry place. The refrigerator is a great option, as walnuts stay fresh for up to three months. Shelled walnuts stay fresh in the pantry for about 12 months. Of course, it's not that after that period all nuts are discarded.
But chances are that at least some of them are dry or stale, and some of them are stale. Shelled walnuts can last up to 12 months, maintaining their freshness and quality. However, once you remove the housing, the life of the nut decreases significantly. Shelled walnuts are stored for at least half a year at room temperature and more than a year in the refrigerator.
On the other hand, shelled walnuts last at least 3 months in the pantry and more than 12 months in the refrigerator. Shelled walnuts require much more care and caution than their shelled counterparts. When they are in their unopened package, they can last as long as their expiration date indicates. Outside of the package, the situation is totally different.
Due to their high fat content, walnuts turn rancid relatively quickly once exposed to the elements. Even when stored perfectly, they can only be expected to last up to four weeks in the pantry. Because of this, it is much better to transfer the nuts to a sealed container as soon as they have been opened. When placed in the fridge, the shelf life can be extended up to 6 months.
However, as time goes on, you may notice that one or two are starting to get bad before the others. Properly stored shelled and shelled walnuts last up to a year in the refrigerator. All you have to do is put them in an airtight container or store them in their bag if it wasn't open. Everyone, including me, agrees that going with the fridge or freezer is the best option if you want nuts to last as long as possible.
Nuts should maintain quality for about 12 months in the refrigerator and 24 months in the freezer (FK, UOC). However, walnuts do not spoil if they are not opened. If stored in the refrigerator, they will stay cool for about nine months; if stored at room temperature, they will stay cool for about six months. Once opened and exposed to air, walnuts are best consumed within 7 to 10 days for maximum freshness.
Naturally, when you buy nuts that are still in the shell, they have an additional layer of protection against these harmful elements. Walnuts last 2 to 3 months in the pantry, 8 to 12 months in the refrigerator and 12 to 18 months in the freezer. And that's why most people prefer to put shelled walnuts in an airtight box after opening the store-bought package. An exception is vacuum-sealed black walnuts, which can keep their flavor and nutrients intact for up to a year if stored at room temperature.
The shell is an excellent protective barrier, so shelled walnuts last longer and have less stringent storage requirements. Speaking of shelled walnuts, they become vulnerable to moisture and oxygen as soon as they are shelled. If the nuts are OK, but taste a little stale, and maybe not as crunchy as you would have liked, you can fix it. In addition, unopened nuts should be stored in a cool, dark area, such as a pantry, for about six months.
Since you plan to eat only a small amount every day, the package of shelled walnuts you bought will last quite a long time. They are usually eaten immediately, but you can preserve the taste and texture of nuts by drying, freezing, or pickling them. First, that date is not an expiration date, just a rough estimate of how long nuts should last. If you like the idea of adding nuts to your baked goods and other recipes, you'll probably prefer to buy a large batch of nuts and use them as needed.
If you think that estimate isn't quite right, especially for shelled walnuts, you're in the right place. Food Keeper says the shelf life of walnuts is very limited, such as 2 to 4 weeks of storage for both shelled and shelled walnuts. Keep in mind that stale walnuts often turn much darker in color, but it is often difficult to distinguish them by color alone. So, if you shake your shelled nut and hear the walnut moving inside it, it's time to throw it away.
