How long do nuts last? - Healthy Food Guide? ›

Raw nuts can be stored in an airtight container in a cool dark place for six to 12 months. The fridge or freezer is ideal. Nuts can be refrigerated for up to four months and frozen for up to six months. Store ground almonds in an airtight container in a cool dark place for a couple of weeks.

Shelf life of raw nuts

Depending on the type, they can range from six to nine months when stored in a pantry or other dry place. However, some types, such as pine nuts, have a shorter shelf life of approximately two months. On the other hand, almonds can last the longest, approximately nine to twelve months.

If a nut is only slightly stale, says Kanney, it can usually still be toasted to revive some of its previous glory and (crunch). However, Kanney says, “If a nut has spoiled or gone rancid, recognizable by a sour or bitter flavor, the nut is no longer good and should be thrown away.”

Almonds, walnuts, and pistachios are lower in fat, so they'll generally last longer than nuts higher in fat, like macadamia nuts, pine nuts, cashews, and Brazil nuts, all of which will go rancid quicker, says LaMarita.

Counter / Pantry / Room Temperature

Storing nuts/seeds at room temperature will reduce their shelf life. Shelled nuts and seeds can last from one to three months. Unshelled nuts may keep up to two years. If you live in a warmer climate, I would only keep them on the counter for up to a month.

“If a nut is really oxidized, I guarantee you you're not going to get it past your mouth because it just tastes so awful,” says Schaich. But if you do, for some reason, eating the occasional spoiled nut is “no big deal,” because we have enzymes in our stomachs that can essentially incinerate the oxidation byproducts.

A cool temperature of <50°F/<10°C is optimal, but a higher temperature that does not stimulate insect activity may work as well to control moisture migration (and also minimize lipid oxidation). Almonds are a shelf-stable nut that can have more than two years of shelf life when stored at the recommended conditions.

BHF dietitian Victoria Taylor says:

Brazil nuts, cashews and macadamia nuts are higher in saturated fat. Too much of this can contribute to raised cholesterol levels, so only eat them occasionally. Chestnuts are an exception – they're lower in all types of fats and higher in starchy carbohydrate than other nuts.

Nuts smell sour and rancid and aren't quite pleasant. In terms of texture, stale nuts tend to feel softer and lose their trademark crunch when stale. Lastly, rancid nuts taste just like how they smell – sour and bitter.

Is it better to freeze or refrigerate nuts? ›

When storing nuts, the freezer is your friend. This dark, cold space slows the deterioration of the nut's oils, a process that directly impacts flavor. Light, oxygen, and heat are the enemies of nuts.

Spoilage is accelerated even more in the presence of light, oxygen, and heat. Storing nuts (and seeds) in the fridge or freezer limits their exposure to all three of these, and will result in your nuts tasting less bitter and more flavorful for a longer period of time.

Nuts' fragile unsaturated fats can go rancid quickly. While that may not hurt your health, it can definitely be bad news for flavor. Keep nuts tasting fresh by stowing them in a sealed plastic or glass container in the refrigerator for four to six months.

Even if the bag's been opened, shelled nuts should last an entire year, and in-shell nuts will last about a year and a half.

Once past this date, foodstuffs may still be consumed (provided the given storage instructions have been followed), as their consumption does not represent a food safety risk, although the organoleptic properties and the aspects that distinguish the food - such as taste and smell - gradually deteriorate.

Spoilage is accelerated even more in the presence of light, oxygen, and heat. Storing nuts (and seeds) in the fridge or freezer limits their exposure to all three of these, and will result in your nuts tasting less bitter and more flavorful for a longer period of time.

They told me that with all nuts (raw, roasted and ground) and seeds, the best idea is to buy as fresh as possible, in small amounts and to use quickly. Raw nuts can be stored in an airtight container in a cool dark place for six to 12 months.
