Walnuts in shell are kept for a couple more months, about 6.Most shelled nuts retain their quality for about 4 to 6 months at room temperature. Walnuts in shell are kept for a couple more months, about 6 to 9 months. If you decide to refrigerate the nuts, extend that period by 50 to 100 percent. Freeze the nuts if you need more time.
Almonds keep their best quality for about 6 months in the pantry or about 12 months in the fridge. Roasted almonds have a slightly shorter storage time. Almonds have a limited lifespan due to the presence of fatty oils in their fleshy part. Fresh unshelled almonds can last four months if stored outside, eight months in the refrigerator and ten months in the freezer.
Shelled almonds can last six months outside, sixteen months in the refrigerator and twenty months in the freezer. Almonds can stay fresh longer if stored in the refrigerator or freezer. Shelled almonds come with an expiration date. When they are not open, they can stay in the pantry for 4 months.
If you open them, you should refrigerate them to last for about 8 months. If you want them to last even longer, freeze them and they'll take 10 months. As soon as you open the pack of almonds, you should try to finish it in a week if you keep them at room temperature or a month if you keep them in the fridge. Since most shelled almonds are found in grocery stores, they don't come with an expiration date.
Maintaining almond quality during long-term storage under ambient conditions is a challenge in emerging export markets, such as China, which may have highly variable temperatures and relative humidities, depending on season and region. You just found a package of almonds in your closet and you're wondering if they're still edible. Almonds freeze perfectly well, and freezing them is the recommended storage method if you want yours to last as long as possible. Almonds should be stored in an airtight container and are best kept in the refrigerator or freezer.
To tell you the truth, it's hard to say precisely how long almonds last, since the recommendations are a bit exaggerated. And if nothing is happening to fish (see the spoilage section for more information) and the almonds aren't stale, don't hesitate to use them. Storing almonds at room temperature for periods of time is not recommended, so your pantry is not a good idea. Shelled almonds are exposed to moisture, oxygen and heat, meaning they will last less than four months.
Because of these interactions, almond shelf life guidelines should specify the product and storage conditions. Shelled almond kernels will probably be fine even if you leave them unprotected in the fridge for a couple of months. If you're not concerned about nut-related allergies, you know how valuable almonds are to your loved ones. When you notice that almonds change color, smell sour, or taste bitter before their expiration date, it doesn't make them good.
And while stale nuts are not dangerous to eat, what I recommend is to throw away stale almonds for quality reasons. Therefore, check the quality of the almonds instead of checking the date and throwing them away if they are “expired”.
