Store shelled walnuts at home. How to store shelled walnuts at home. Now instructions on how to peel a nut from the shell

The properties of walnuts have been known for a long time. Even in Ancient Greece, this fruit was appreciated for its excellent taste, high nutritional value and beneficial qualities. The kernels contain vitamins A, B1 - B6, C, K, E. As well as phosphorus, potassium, magnesium, sulfur, iron, manganese and zinc. They contain a lot of vegetable protein, fiber and essential oils. If you eat 2–3 fruits a day, you can provide the amount of vitamins and minerals your body needs. But you shouldn’t get too carried away with consumption, especially for people with chronic diseases of the digestive system. In order for the beneficial substances in the fruit to remain as long as possible, you need to learn how to properly store walnuts at home and follow the recommendations below.

Which nuts are chosen for storage?

Fruits of regular shape, medium and large sizes, without cracks, with a thin shell are well stored. But at the same time they must be durable to the touch. Fully ripened fruits have a light color and a pleasant, slightly sweet taste.

For saving, choose full-fledged fruits without signs of mold or the presence of pests.

When a large harvest is harvested, the nuts are washed and dried well. But if this is a small batch of fruits, you can heat it in a frying pan or in the microwave.

How long can walnuts be stored?

The shelf life of nuts is determined by the conditions in which they will be located, these are:

temperature regime,
degree of humidity,
lighting parameters,
the material from which the storage container is made.

Standard conditions for long-term savings are described in GOST:

temperature from -15°C (exactly minus 15) to +20°C (without sudden changes);
humidity – up to 70%.

These indicators are optimal for storing nuts for up to 1 year, and their kernels for up to 6 months.

In a cold place (at about zero temperature), and high humidity, the shelf life of walnuts does not exceed 6 months. Frozen fruits will be suitable for consumption throughout the year.
At room temperature (approximately +23°C), the fruits can be kept in fabric bags for up to a year. In a glass container, protected from light, 10-18 months.
Peeled nut kernels are kept in a glass or plastic container for no more than 3 months. And if they are packaged in bags - no more than two.
It is not recommended to keep kernels in a tied bag. With this storage method, they will suffocate and become unusable.

Storing nuts in shell

When sending fruits for storage, they are pre-dried. Excess moisture will quickly lead to their rotting and mold development.
The remaining part of the peel is removed.
When there are a lot of fruits, they are dried in the fresh air in clear weather. But a ventilated balcony, as well as an attic space, are also suitable for these purposes. Place the nuts on newspapers in one layer (you can use fabric). Then they are regularly turned over every 2-3 days for uniform drying.
A more effective method is oven drying at +60 - +65°C. Roasting in the oven will also destroy pest larvae. At this temperature, you need to keep the fruits in the oven for at least 2 hours. They are also often dried in metal containers on a hot radiator.

Experienced housewives believe that proper storage of walnuts in their entirety occurs at a temperature of -5°C -+10°C. Fruits should be kept in low humidity, especially if they are in fabric bags.

It is unacceptable to keep the crop under the sun's rays. When the nuts are in a glass container on the balcony, you need to cover them with something. It’s better to hide it on the shelf of a closed built-in cabinet.

When fruits are exposed to high temperatures, a significant portion of the vitamins are destroyed. The taste becomes bitter due to changes in the structure of oils that are present in large quantities in the kernels.

The container in which it is best to store walnuts can be:

cardboard,
plastic,
wooden.

The bottom of the box is covered with corrugated cardboard or wax paper. Walnuts are stored in wooden containers on racks, and if the fruits are in bags, they are hung.

Rules for choosing peeled walnuts

When purchasing walnut kernels, you can immediately see the product, which on the one hand is good. But the shelf life of kernels is shorter than that of whole fruits. Therefore, it will not be possible to store peeled walnuts for a long time.

A freshly cleaned product has a presentable appearance, without dark spots or marks of insect activity. It is important that the kernels are the same color. This is an indicator that all the kernels are from the same batch, and the seller did not mix stale goods into them.

It is not worth buying an already crushed, purified product: no one can guarantee the quality of the raw materials.

You also cannot buy kernels in spontaneous markets located right next to the roadway. They absorb dust and car exhaust gases very well. On their surface there may be various harmful bacteria and even E. coli. It will be pointless to talk about the beneficial qualities of such a product.

Before purchasing, be sure to try what you are about to buy. The slightest taste of bitterness or musty unpleasant odor should deter you from purchasing this product.

Storing walnut kernels

The nut, peeled from shell and partitions, is kept at a low temperature in tightly closed containers made of glass or metal. They should be isolated from sunlight and located in places with humidity not exceeding 70%.

Nuts are not only a tasty food product, but also a source of a number of useful components. Only if you know how to store nuts can you count on their therapeutic effect on the body and their stated nutritional value. While shelled products are not too demanding on maintenance conditions, cleaned components require a special approach. When organizing the process at home, you should pay attention not only to the universal rules, but also not to forget about specific points.

Features of the preparatory stage

Not all nuts can be stored for a long time. Therefore, first of all, you need to learn how to choose a product. Here you should be guided by the following nuances:

You should never buy shelled nuts. Firstly, it is impossible to determine their expiration date. Secondly, they could have been fumigated or sprayed with something, which would negatively affect not only their storage, but also their taste characteristics. Thirdly, the features of self-processing can extend the shelf life of products.
Nuts, whether shelled or in shell, should emit a subtle, characteristic odor. If there is even a suspicion of mold, rancidity, or excessive moisture, you should not buy them.

Advice: It would be a good idea to inspect the bag in which the products were stored or transported. The burlap should be free of traces of larvae, insects, dirt, mold and suspicious stains.

You should try the nuts before you make a purchase. At the same time, we use not the product that is on the display case, but the one that is in the bag. We open the shell with our own hands and taste the kernel. If it is very soft, bitter or wrinkled, you shouldn't even try it again. It's better to abandon the entire batch and find another one.

At home, you should not try to store nuts that were in a plastic bag until the time of sale. They can look very fresh and appetizing due to prolonged lack of contact with oxygen. When exposed to new conditions, products quickly begin to rot, no matter what they are stored in or how they are cared for.

Regardless of what nuts are to be stored, there are several universal rules for their content. Compliance with them will maximize the preservation of nutrients and beneficial substances in the components and reduce the risk of spoilage.

Immediately after purchase, the components must be sorted out and dried a little on a horizontal surface with access to fresh air. If the products are very dirty, they should also be washed. By the way, nuts that float can be thrown away; they are empty inside.
Even if you know how to store nuts according to all the rules, you should not immediately collect a large amount of product that will be used for preparation. Ideally, nuts should be eaten within 2-4 months. They, of course, can sit for more than a year, but their taste will definitely change.
While in-shell products should be kept in bags that allow air circulation for the components, cleaned kernels should be stored in sealed zip bags, glass jars or plastic containers. The presence of air affects them in the most detrimental way.
Product storage temperature can be room temperature, humidity – average. The main thing is that these indicators are stable and that direct sunlight does not fall on the nuts.
Peeled nuts can be stored unchanged for six months. To do this, they need to be frozen quickly using plastic containers or bags. After defrosting the products, re-freezing them is prohibited.

Ideally, it is better to even dry nuts yourself, at home. This will slightly extend their shelf life and guarantee a pleasant taste of the product during this time.

Specifics of storing walnuts and hazelnuts

Walnuts are famous for their high content of healthy fats, due to which the components begin to deteriorate faster than many other nuts - they develop a rancid taste. To prevent this from happening, when storing them you must adhere to the following rules:

Fry fresh peeled kernels in a hot frying pan without adding oil for 15 minutes, stirring constantly. Then we cool the product naturally and send it for storage.
If you plan to use the product within a couple of weeks, place it in a plastic or glass container with an airtight lid. Place in a dry, dark and warm place. If you place the container in too humid conditions, mold may grow inside the container.

When you need to save nuts for 2-3 months, put them in a very dry container, close them and place them on the top shelf of the refrigerator (away from the freezer).
Frozen walnuts are best stored wrapped in cling film. As needed, defrost them and warm them in the microwave for 10 minutes. Then they will be even tastier.
Contrary to popular tradition, walnuts are not stored in shells!

When it comes to hazelnuts, things are a little different. The product in the shell can be stored for 2-3 years, however, over time, its taste properties will begin to deteriorate. To obtain optimal results, the component should be kept at a temperature of 10-12ºС and a minimum humidity of about 20%. Peeled nuts are stored in exactly the same conditions, but they need to be eaten no more than 3 months in advance. After this, the products become not only not very tasty, but also dangerous.

Points to pay attention to when working with pine nuts

Pine nut kernels are approximately 65% oil, so they also cannot be stored at home for a long time. Practice shows that even the use of a vacuum in this case will not significantly increase the shelf life of products.

You can expect optimal results if you follow these rules:

It is best to buy products in early autumn, this is when they are collected. Before purchasing, be sure to try the core. Its pleasant and delicate taste without the slightest sign of bitterness will help make sure that this is not last year’s product.
Fry the nuts in the shell for a quarter of an hour in a clean, hot frying pan, stirring constantly. Cool the mixture, pour it onto a horizontal surface and dry it for a couple of days.
We put the finished product in the shell into canvas bags and place it in a dark, dry and warm place. It is better to put the peeled kernels in a glass or tin jar and put them in the kitchen cabinet.

If the situation is such that you have to purchase products packaged in bags, be sure to check the expiration date of the product. If it was packaged more than 6 months ago, it is better to refrain from purchasing it.

Many housewives like to stock up for future use, but while the techniques for preparing preserves are known to many, only a few know how to store nuts. It is not enough to bring the product from the store and store it on a free shelf; you will have to carry out several important manipulations, especially if you need to save the peeled kernels. The approaches used for this at home are practically independent of the type of product. If desired, you can choose the best option for affecting hazelnuts, walnuts, pine nuts and even the more exotic cashews and macadamia.

Universal instructions for harvesting nuts

The success of the event directly depends on the ability to choose a quality product.

When choosing shelled or inshell nuts, you need to remember the following points:

The food product should emit a very subtle and pleasant aroma. It should clearly capture the notes characteristic of a particular type of nut. At the slightest hint of rancidity, mold or high humidity, you should refuse the purchase.
You need to try nuts before buying. Moreover, this should not be the product that is on the display case in a cleaned form, but a copy that has been opened with one’s own hand. Bitterness or excessively soft texture are obvious signs of a spoiled ingredient. You shouldn’t try again, thinking that you just got a bad nut; it’s better to abandon the entire batch.
Even if you need to store shelled nuts, it is better to buy them in shells. Self-processing of blanks will maximize the shelf life of products.
It would be a good idea to inspect the bag in which the components were stored. You need to make sure there are no larvae, adult insects, mold or strange stains on the burlap.

Tip: It is highly recommended not to purchase a product that was originally packaged in plastic. Often such products begin to rapidly deteriorate immediately after being exposed to new conditions. This is explained by the long absence of contact of nuts with oxygen, which allowed them to remain in the desired state.

Experts do not recommend purchasing too many nuts at once. Even though there are approaches that can preserve the product for a year, the taste will still change. It is better to determine how much product will be eaten within 2-3 months and limit it to that.
The main factor that causes shelled nuts to rot quickly is air. While it is recommended to keep in-shell products in canvas bags that allow constant air circulation, bare kernels should be placed in airtight glass jars or plastic containers.
Storage temperature must be stable. The products are preserved well at room temperature and standard humidity, the main thing is that the products are not exposed to direct sunlight.
To preserve shelled nuts for six months, you can use the freezer. Pre-processed kernels are placed in plastic bags and frozen, preserving all the beneficial properties. Re-freezing is prohibited!

In addition to the above points, there are also specific recommendations that apply to walnuts and pine nuts. Cashews are stored only in their purified form, at room temperature, in the refrigerator or freezer. The shelf life ranges from 1 month to 2 months and six months, respectively. Hazelnuts are very undemanding to conditions due to their special texture, but they will not retain their properties for more than three months at room temperature or six months in the freezer.

Features of storing walnuts

Walnuts are high in healthy fats, but it is for this reason that they acquire a rancid taste and smell faster than other types of products.

The fresh product must be fried in a hot frying pan without oil for a quarter of an hour. After such processing, the product is cooled and sent for storage.
If the nuts will be eaten within 1-2 weeks, they can be poured into a glass or plastic container with an airtight lid and stored in a warm, dry and dark place. If the humidity is high, mold may grow on the nuts.
To preserve the freshness of the product at home for 2-3 months, you need to place the product in a dry container without a drop of liquid and place it on the top shelf of the refrigerator.
Walnut kernels can be stored in the freezer for up to a year. They need to be wrapped in cling film and the unit set to fast freezing mode. Before consuming such products, you need to not only defrost them, but also heat them in the oven for about 10 minutes, then the kernels will become even tastier.

Important points in storing pine nuts

In this case, again, it is not recommended to purchase peeled nuts; the best option would be to process the cones yourself and form blanks. To obtain the optimal result, we consistently perform the following manipulations:

First, the cones need to be lightly burned over an open fire or heated in a regular frying pan. We clean the cooled specimens manually or using a special mill to extract the nuts.
Fry the resulting nuts again in a dry frying pan for a quarter of an hour. You need to stir them constantly, otherwise the product will burn.
Next, lay the workpiece on a tarpaulin and dry it in a dry, warm room for 2-3 days, stirring occasionally. You can additionally cover the embankment with a tarpaulin.
Place the finished product in bags made of canvas or soft fabric. We put them in a dry, dark, warm place, inaccessible to rodents and insects.

In this form, the product can be stored for up to six months. Purified nucleoli can be stored for no more than a couple of months. To do this, put them in dry and clean plastic bags, which we seal tightly and put in the refrigerator. If cedar kernels need to be preserved for three months, then they must again be kept in the refrigerator, but not in polyethylene, but in a glass jar with a tight lid.

Regardless of the chosen approach, the product must be regularly tested, the stock must be cleaned of missing kernels, and in some cases even additionally calcined (if a specific smell of high humidity appears).

Walnuts are loved by many, have high nutritional value and a large supply of vitamins, minerals and unsaturated fatty acids. However, not everyone knows how to properly store peeled walnuts. Our article will talk about how to stock up on healthy products in the fall and store them until the next harvest.

Choosing nuts for storage

Not everyone has the opportunity to independently harvest nuts directly from the tree. Most people buy the product from the market. Here the consumer is faced with a choice: buy nuts in shell or shelled, ready to eat. It is more difficult to choose high-quality nuts in shell, because the contents are not visible behind the shell. But storing walnuts in shell at home is easier.

With the purchase of peeled kernels, everything is much simpler, because you can immediately determine the condition of the fruit by appearance. What should you consider when choosing? Pay attention to the following parameters:

choose clean, dry nuts, without darkening or stains;
the kernels should not have foreign odors, especially chemical ones;
taste the nut. If it has an unpleasant bitter taste or the kernel inside turns out to be darkened, you should refuse to purchase.

If everything is nuts same color, which means they were collected during one season and not mixed with last year’s harvest. Best choice for storage whole kernels, since broken pieces deteriorate faster. You need to make sure that the nut has no mustiness smell or whitish coating. If it is a little rotten, even airing and drying will not help. Spoiled fruits not only cannot be stored for long periods of time, but can also be hazardous to health.

Basic principles of storage

In order for nuts to remain tasty and of high quality longer, you need to remember the following factors that affect their shelf life:

temperature regime. The higher the temperature at the storage location, the shorter the shelf life of the fruit;
ripeness. Unripe kernels are not suitable for saving;
availability of additives. Peeled nuts must be carefully sorted before storage. Among the kernels there should be no pieces of shell or bridges, as well as low-quality fruits. You should not save nuts by mixing them with sugar, honey or other ingredients - this will shorten their shelf life significantly;
treatment. Nuts should not be cooked before storage. People often confuse drying and frying and make an irreparable mistake. You can dry the peeled fruits a little, but it is best to do this immediately before using them for food. Only unshelled nuts can be roasted;
storage container. Avoid plastic bags as containers except for freezer storage;
storage. Only if stored in the freezer and maintained at a constant temperature can you count on a long shelf life - about a year. Thawed fruits cannot be re-frozen.

If you keep these factors in mind, it will be much easier to preserve nuts not only until winter or spring, but also until the next harvest.

Storage methods

Next, let's talk about how to store shelled walnuts at home. The shelf life of peeled nuts directly depends on the storage method. If you need to save kernels for daily use for a month, you can place them in a glass jar, tightly close with a plastic lid and place on a kitchen cabinet shelf. How long can nuts be stored in this form? This method is appropriate when storing a small amount of fruit that will be used within 20-30 days.

Glass or metal dishes will help keep nuts fresh for up to 1 year; they can be stored in wooden boxes or fabric bags for 3-4 months.

Do not store kernels at room temperature for a long time. Regardless of whether you bought peeled fruits at the market or prepared them yourself, you won’t be able to store them for a year in your apartment. After lying in a warm place for a long time, the nuts acquire a bitter taste, dry out and lose their appetizing appearance. They will not only become tasteless, but can also be harmful to health.

Before putting the nuts in the refrigerator, you can keep them in a hot oven for a short time, avoiding the release of oil.

To eat healthy nuts all year round, it's best to save them in a refrigerator, they will stay fresh there within 6 months. For containers, be sure to use sealed containers made of glass, ceramics or food-grade plastic. For convenience, some housewives immediately chop the product in order to get ready-to-use nut crumbs out of the refrigerator. If you are confident in the quality of the nuts, they can be stored in the refrigerator in any form.

Alternatively, you can store the fruits in the cellar or on the balcony, but in this case you need to monitor the humidity level in the room. If it exceeds 70%, the nuts will soon become moldy.

Another proven storage method is freezing. Place the peeled kernels in sealed bags and place in the freezer. Food foil or film is also suitable for packaging. It is not recommended to store kernels near strong-smelling foods to prevent the absorption of foreign odors. The shelf life of frozen walnuts is up to 12 months.

To learn all the intricacies of storing walnuts, it is better to read the reviews of gardeners involved in growing and selling them. The main condition for long-term storage is a high-quality starting product. If you have selected fresh fruits, use our tips to enjoy the valuable kernels longer.

Nutritionists around the world recommend eating it regularly for those who adhere to diets, have given up eating meat and are experiencing constant physical and mental stress. However, few people know how to properly store shelled walnuts so that they do not lose their beneficial properties.

Why walnuts are indispensable in nutrition

Walnuts contain not only a unique complex of vitamins and minerals, but also protein, which can completely replace its animal counterpart in nutrition, and fats. However, despite the fact that more than half of the percentage is fat,

The secret lies in the fact that these fats are unsaturated. The only disadvantage of their high content is that they cause a high calorie content of the product.

Due to their high nutritional properties, the presence of a vitamin-mineral complex and biologically active components, walnuts are indispensable for nervous and physical exhaustion, for vitamin deficiencies, and for increasing the body's defenses. Their regular use reduces the likelihood of many diseases and allows you to maintain an optimal balance of vitamins and minerals in the body.

Walnuts are an invaluable source of energy and have no contraindications for consumption. But all these comments are valid if they are stored correctly.

How to choose correctly

Walnuts are sold in shells and shelled. They last longer in the shell, but if you buy the product at the market, there is no guarantee of good quality and pleasant taste, since it is difficult to determine through the shell which nut is inside. Buying shelled nuts, although more expensive, is more convenient.

First of all, they don't need to be cleaned.
Secondly, whether it is good or bad can be seen immediately in the purified version. But there is also a secret here: it is preferable to choose whole, shelled nuts rather than scrap.

Nut crumbs and pieces of kernels cannot be stored. Whole kernels are stored longer. But even when buying peeled whole nut kernels, it is important not to let your guard down. A good product should not have a musty smell or a whitish coating. A product with these signs is unsafe for health.

How to properly store shelled walnuts

Since walnuts are perishable products, it is important not to buy them for future use and ensure proper storage conditions. To prevent them from going rancid, the kernels should be stored in a dark, hermetically sealed container. Plastic bags in which goods are hung must be immediately excluded.
