Do unopened walnuts go bad?

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 are kept 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. Expect shelled walnuts to last a year in the pantry and about 1 to 2 months past their expiration date. Walnuts have a fair shelf life, which lasts up to 3 months with the shells set at room temperature. When the shells are removed, the nuts oxidize much faster and only stay fresh for a couple of weeks.

However, nuts will 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. Place cardboard or plastic tarpaulin under the black walnut tree before picking fresh walnuts to avoid this problem.

Because of this, it is much better to transfer the nuts to a sealed container as soon as they have been opened. Similarly, you could also end up accidentally shortening the shelf life of your nuts if you're not careful. Therefore, it is advantageous to know how to check if a nut is still fit for consumption or if it has passed its prime. To maximize your supply of shelled walnuts, store them in a sealed plastic bag in the refrigerator and plan to use them within nine months.

However, possibly the most annoying thing about walnuts is that some that have left will go through these tests undetected. If you buy walnuts in a sealed package, you can store them in their original packaging in the refrigerator or freezer. The California Walnut Board was established in 1948 to represent California walnut growers and handlers. For shelled walnuts, pack those nuts in a freezer bag or airtight container and place them in a cool, dry place.

They can last quite a long time when they are still in an unopened container, provided the expiration date is indicated. Therefore, you should store them in the unopened package or in an airtight container in the refrigerator or freezer. Now, if you can't put the walnuts in the fridge, let's talk about storing them at room temperature. However, when a nut goes stale, it will feel light when you shake it and you can hear the grain moving around the shell.

In other words, instead of relying on the printed date, you should do a quality check on your nuts and go from there. Chances are that at least some of the kernels are still intact, even if those nuts are already two years old.
