How to Store Nuts So They Don't Go Rancid? ›

Immediately transfer nuts to an airtight container.

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.

However, you need to make sure that the pantry is cool, dark, and dry, as high temperatures, light, and humidity can speed up the rancidity process. You also need to keep the nuts and seeds in airtight containers or resealable bags to prevent exposure to oxygen and insects.

Avoid storing nuts near heat sources like stoves, ovens, or direct sunlight. Instead, choose a cool and dark storage location to extend their shelf life.

The Best Way to Store Nuts

That's right, it's the freezer and Bryan Roof, Editorial Director at Cook's Country agrees. He says that the freezer is the best place to store nuts because it's dark and cold in there. Same goes for seeds.

A: Nuts can't expire; however, they can change in taste or go rancid. Nuts contain much-unsaturated fat, an oil that makes nuts likely to go rancid. Nuts spoil faster when exposed to light, air, or heat. No fuss; cool, dark, and air-sealed are the three trifectas to storing nuts properly.

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.”

At room temperature, nuts and seeds can start to go bad after anywhere between one and three months, though some brands will advertise longer shelf lives than that. If stored in the refrigerator, however, these healthy fat sources can last up to six months.

Store shelled or unshelled walnuts safely in an airtight container and store in a cool, dry place. The refrigerator is a great choice as walnuts will remain fresh for up to three months. You can also freeze walnuts for up to one year.

"Nuts have a wide range of fat contents," says LaMarita. 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.

Can nuts go rancid in freezer? ›

Whole raw nuts can be stored in the freezer for up to one year. Chopped nuts, ground nuts, or nut flours — all of which contain more surface area for oxidation — are quicker to spoil and should only be stored for up to six months.

Just toasting them in a dry pan or oven should be enough to revive them, but they'll also go in any recipe that requires nuts. We got through most of ours by toasting them with spices, to eat as nibbles or to add crunch to soups, stews and salads. I also made a vivid green marzipan with some of the pistachios.

A mason jar or TV3 container is a great solution that can help you store your shelled nuts out of the elements and preferably in the refrigerator, as this will keep them fresh for up to six months at least, even up to a year.

Light exposure can also deteriorate the fats in nuts, so storing them in a dark environment or opaque containers can prolong their storage duration. Similar to other perishable foods, storing nuts in a cooler location is important.

While our tables list the time frame that nuts are good beyond their printed date, if you can't find any date on your package, you can expect most shelled varieties to last about 2 years. For opened packages, it's best to take a whiff before serving.

Glass jars that have been vacuum sealed with a food evacuator are the gold standard, says Schaich. The second best: Put your nuts in a resealable plastic bag and press out as much air as possible before sealing, then store the bag in a glass container.

When your refrigerator stash is running low, it's time to "refill from the freezer to the jars in the fridge." Stored in a sealed container in the refrigerator, nuts will last for four to six months, according to the Academy of Nutrition and Dietetics. Meanwhile, in the freezer, they'll last for at least one year.
