How to Store Hazelnuts

The key to storing hazelnuts is keeping them away from the things that make them spoil faster. This includes direct sunlight, heat, oxygen, and moisture.

It’s also worth mentioning that before you store them, make sure the nuts themselves are completely dry. Otherwise, they’ll become moldy within a short time.

Storing Shelled Hazelnuts vs. Unshelled Hazelnuts

If you have some unshelled hazelnuts, then you’re in luck! That’s because storing hazelnuts with their shells intact is the best way to keep them fresh for a long time.

This is because the shells act as individual natural wrappings for the nuts. So, they’re protected against light and moisture, as well as any potential bacteria and mold growth.

For safekeeping, place the unshelled hazelnuts in an open bag or container. Then, set them in the fridge or freezer.

If you have shelled hazelnuts, you can store those in ziplock bags or airtight containers in the fridge or freezer. However, keep note that hazelnuts tend to absorb odors from nearby foods. So, avoid placing them anywhere near highly pungent foods like onions or garlic.

You wouldn’t have to worry about that with unshelled nuts. Their shells protect them from picking up any unwanted odors.

Can You Freeze Hazelnuts?

The best way to store hazelnuts long-term is to freeze them. According to studies conducted at Oregon State University (OSU), you can keep hazelnuts fresh in the freezer for up to a year at 32°F.

They can even stay fresh for over two years if stored at 0°F. The good news is that they can be thawed and refrozen several times without losing their taste, texture, or nutritional value.

To defrost your hazelnuts, simply leave the bag at room temperature until they’re warm. Then, you can either roast them and enjoy them as a snack or chop them up and add them to whatever delicious recipe you’re making.

Containers for Storing Hazelnuts

Whether shelled or unshelled, hazelnuts are pretty low-maintenance when it comes to storage. You can place them in resealable bags or airtight containers that block out air and moisture.

You can also use special vacuum jars or a FoodSaver to suck out the air around the nuts. As an alternative, you may choose to leave the jar of unshelled hazelnuts open. This way, all that extra moisture can easily escape.

Mason jars are a great choice for storing shelled hazelnuts. For starters, they’re great at keeping pests and odors away from the nuts. Plus, they can also be vacuum sealed for maximum protection against mold and bacteria.

What is the Shelf Life of Hazelnuts?

The temperature at which you store hazelnuts drastically affects how long they’ll remain fresh. In other words, the lower the temperature, the longer the hazelnuts will stay fresh and tasty.

Fridge9 months
Freezer2 Year

Note: the numbers we’re giving here are based on estimates provided by nutritionists and food experts.

Pantry

In general, we recommend you store hazelnuts in a cool, dry, and dark area with a low temperature. Yet, sometimes storing them in the fridge or freezer isn’t accessible, so your next best option is to put them in the pantry. Just make sure the temperature doesn’t go higher than 55°F, or else they’ll start to lose their flavor.

Shelled hazelnuts can last in the pantry for up to three months. In contrast, unshelled nuts can last for a maximum of six months.

Refrigerator

Storing shelled hazelnuts in the fridge allows them to stay fresh for up to 12 months. Unshelled nuts, on the other hand, can last up to a full year in the fridge as long as they’re stored properly.

Freezer

In the freezer, hazelnuts can last for up to two years. It’s a good idea to always label your freezer bags with the date of packaging and use old batches before new ones.

How to Tell if Hazelnuts Have Gone Bad

If you have any doubt about the quality of the hazelnut, it’s better to dispose of it than consume food that has gone bad. Here are a few tell-tale signs that your bag of hazelnuts is unsafe to eat:

Unpleasant Smell

Hazelnuts that have turned rancid will have a strong unpleasant smell and a bitter taste. Some people describe rancid nuts as having a chemical smell reminiscent of nail polish remover or old paint.

Rancidity occurs when the oil in nuts breaks down in the presence of oxygen. In large quantities, eating rancid hazelnuts may cause an upset stomach, vomiting, and diarrhea.

Mold

When hazelnuts are stored in areas with high moisture levels, they can start to develop fluffy white mold growth. This renders the whole bag of nuts inedible.

Moldy nuts contain aflatoxins. These chemical compounds can be carcinogenic and poisonous when ingested. They also irritate the lungs and airways when inhaled.

Pest Infestation

Some common pests that love snacking on your hazelnuts are hazel aphids and filbert worms. So, if you see any small insects or larvae that look like tiny worms in the hazelnuts or the container, throw them out immediately.

People Also Ask
