How to store walnuts at home, peeled and in shell
A storehouse of vitamins and minerals, walnuts, are especially relevant in early spring in the diet of both adults and children, starting from the age of two. It is during this period that the supply of natural vitamins in the form of fresh fruits and vegetables ends. And this healthy food product is always at hand if stored correctly.
How to clean the shell correctly
It would seem that it could be easier than taking a hammer, hitting harder – and you’re done. However, in this case, the kernel will be crushed and mixed with the shell. It will be inconvenient and time-consuming to select the surviving pieces of nuclei.
There are several ways to peel walnuts from the shell at home, which will keep the kernels intact and not deformed. Thanks to these methods, there is practically no waste (except for the shell itself).
Whole kernels are not only pleasant to eat, but also convenient to use for confectionery purposes – for example, for decorating cakes.
Before you start cracking nuts, it is imperative to prepare them for this procedure: place them in an oven preheated to + 200 ° C for 10-15 minutes.
The hard shell prepared by the above method can be easily cracked using the methods described below.
In a slider package
After the fruit has cooled, place the three in a heavy-duty polyethylene slider bag.
After you hit this bag on a cutting board, the shell will surely crack, since it has become very fragile due to the heat treatment in the oven.
The package is necessary so that the shell does not scatter in different directions throughout the apartment. Next, you should remove the shells and kernels from the bag and separate the halves of the kernels from the inedible parts. This will give you six halves.
A bottle of champagne
The next type of cleaning requires an empty wine bottle with a concave bottom. Place the walnut on a cutting board and lightly hit it with the concave side of the bottle. It is necessary that it falls into the hollow at the bottom of the bottle.
Sometimes you need to turn the nut over and repeat the strike. The kernel often remains completely intact using this method.
If you have such a tool on your farm, it will not be difficult for you to peel walnuts from the shell.
The plumbing wrench has a stop that will allow the pressing parts of the appliance to be set to a certain compression width . The fruits are approximately the same size, so you only have to do the markup once.
Then you need to insert the nut into the gap between the pressing elements of the key and lightly press it down – the shell instantly cracks.
If you don’t have such a key at home, you can use pliers, but you need to squeeze them carefully so as not to flatten the core completely.
This method is very effective, but only suitable for tidy people. It is necessary to insert the edge of a knife into the blunt end of the nut, at the junction of its halves – where the side of the fruit is blunt and wide, and not sharp. Then slowly loosen the shell at the junction until it splits in two. After that, remove the cores, helping yourself with the same knife.
The sharp side of the hammer
You can easily and neatly break the shell with a hammer without damaging the valuable interior. However, you need to know where to hit and which side of the hammer to hit.
Important! The sharp side of the hammer will reduce the impact area, thereby preventing the fruit from being crushed completely .
Place a waffle towel on a wooden cutting board and place a walnut on top of it. With the sharp, not blunt, side of the hammer, strike perpendicular to the line where the halves join.
How to dry nuts
Drying a nut is a very important and necessary stage in preparing it for storage. Fresh walnuts contain about 40% moisture and therefore easily decay. If all the drying conditions are not met, it will not be possible to preserve the fruits for a long time.
If you have a dry wooden shed or shed on your farm, you can scatter the harvested crop in one layer on natural material or in hay and leave the fruits to dry naturally for a period of 2-3 weeks.
Drying in the open air is not recommended, since during this time, most likely, it will rain at least once and spoil the whole process – in this case, the shelf life of the fruits will be zero.
This old home drying method has other disadvantages as well. For example, during a period of such a long stay on the ground, insect pests or microorganisms can make their way into the fruits, which can completely destroy the crop.
Natural drying in wire rack
This method is used by modern farmers, whose harvest volumes are large enough. Thrifty owners strive to preserve the highest quality product in full, while allocating minimal investment for the drying process itself.
Also find out how many walnuts you should eat per day.
A dry, well-ventilated room with intensive air circulation is allocated for storage. Preliminarily, special containers are made of dry timber – lattice trays.
Nuts are washed in cold water and placed on a drying tool in one layer. Then the trays are placed in special racks. The latter are made in such a way as to ensure efficient air circulation between each layer.
The crop prepared in this way is left to dry for three weeks. Such fruits are suitable for consumption, commercial sale, and also as quality planting material. At home, you can also apply the above method. Having made for yourself a rack with lattice trays once, you will forever provide yourself and your family with a properly preserved harvest from your tree.
The artificial drying method is significantly more expensive than natural drying, but it is quick and effective.
If it is necessary to prepare nuts for long-term storage, they must be dried, without peeling from the shell, in an oven preheated to + 90 ° C for 2-3 hours.
Then the oven must be turned off and the product left there for as long as it takes to cool. After this treatment, your crop can be consumed gradually throughout the winter period.
Peeled nuts can also be dried in the oven, but large stocks should not be made, since without their natural protection, the kernels crumble and quickly deteriorate.
The kernels should be laid out on a baking sheet covered with foil so that they do not come into contact with each other, and dried for 10 minutes in an oven preheated to a temperature of + 180 ° C.
After 5 minutes, the kernels must be mixed.
How to store unpeeled nuts
Without a doubt, unpeeled nuts have a much longer shelf life than peeled nuts. Their shelf life depends on the variety, the correctness and timeliness of harvesting, drying and storage method.
A cool dry place is considered ideal for storage, where the fruits will be in containers made of natural material: in canvas bags or in wooden boxes.
Important! If you initially protect the nuts from moisture, they will remain in excellent condition until the end of spring.
How to store shelled nuts
Kernels can be stored for up to 1 month at room temperature. After this time, they lose their taste, may become rancid, dry out unnecessarily, crumble or wrinkle.
A glass jar or plastic container is best for storing peeled nuts.
Some housewives who have separate freezers store peeled kernels in them in sealed plastic bags for up to 1 year. It is very convenient to store a pre-shredded product in the freezer for baking confectionery or other purposes.
Important factors for the successful storage of nuts are as follows:
- Compliance with low temperature conditions.
- Moisture protection.
- Peeled nuts are best stored without additives (sugar, salt, honey, etc.).
- Polyethylene is only suitable for storing nuts in the freezer, otherwise only natural materials are suitable.
- Chopped nuts are kept much shorter than whole nuts, and preferably in the freezer.
- Freeze the kernels in small portions, which can be consumed completely after defrosting, otherwise they may deteriorate with frequent temperature changes.
- Nuts with shells can be stored until the next harvest, peeled kernels are stored for no more than 6 months.
How to store green nuts
Green nuts are very beneficial thanks to a substance called juglone. This is a unique antiseptic substance contained in sufficient quantities in young walnut fruits and the outer green pericarp. Therefore, to maintain immunity, as an antiviral, antimicrobial agent, it is important to use green fruit jam and young “milk” fresh kernels.
Unfortunately, it is almost impossible to preserve green walnuts. The only way to store it is to cook jam from these fruits or prepare a tincture with alcohol.
To regularly consume a nutritious and healthy nut product, it is worth spending your efforts not only on collecting it, but also on its proper storage. A well-prepared stock will provide you with nuts until the next harvest.
How to properly store shelled walnuts at home?
Consider the question of how to store shelled walnuts at home. What methods can increase the shelf life without affecting the composition of the product? What role does heat treatment play and can you do without it?
Let’s compare the difference between storing whole and shelled walnuts.
Do nuts lose nutrients over time?
Walnut is a valuable product with a unique composition of minerals and vitamins, a specific set of aromatic and tannins. Protein accounts for a high proportion of 18 to 21%.
Depending on the variety, from 45 to 77% is fatty nut oil, which contains a unique set of saturated and unsaturated acids.
The chemical composition changes slightly over time and largely depends on how the walnuts are stored.
A nut is a fruit bone that performs a storage function. Even with a very long dormant period, the nucleus retains a full set of substances that may be required for the development of a new plant.
A microclimate is created under the shell that can protect the kernel from external influences for a long time. It is not difficult to figure out how to store inshell walnuts at home. It is necessary to maintain a balance of temperature and humidity, a mode of limited illumination.
If the nut is peeled and not protected by a strong bone shell, then the influence of external factors increases. Therefore, conditions are created under which all chemical processes are slowed down, which presuppose:
- restriction of air access;
- lowered temperature.
With strict adherence to the regimes, the product can be stored for up to a year with practically no loss of quality.
Useful properties of walnuts
Shelf life mainly depends on compliance with the temperature regime, which is often a problem in a city apartment. It is also necessary to take into account humidity, illumination, type of packaging material or container.
- Consumer standards describe how to properly store walnuts. The temperature should be in the range from – 15 to +20 degrees, without sudden fluctuations. The limiting level of humidity is 70%. Under these conditions, whole nuts are stored for 12 months, without shells – no more than 6 months.
- The question of how to preserve peeled walnuts without losing quality until a new harvest has an unequivocal answer. Only a refrigerator is suitable for this. On the upper shelves, stocks are stored for six months, and in the freezer for a year.
- At room temperature, which is usually 22-25 degrees, it is permissible to store whole nuts in a canvas bag for about six months, and in glass jars without access to light – up to 10 months. Nuts without shells are stored in glass or plastic containers for up to 3 months, in canvas bags – no more than 2 months.
Keep in mind that nuts ripen in September, early October. This period is taken as a basis when purchasing a product on the market in order to calculate shelf life.
Important! The temperature at which it is permissible to store nuts is in the range from -15 to +20 degrees. The main requirement is the absence of sudden changes in temperature.
How to store in shells correctly?
Full-weight fruits are selected, without traces of damage or cracking. The shells must be free from signs of mold or pest infestation. When harvesting in industrial volumes, the raw materials are washed and dried. At home, it is enough to warm up small batches in the oven or in a frying pan.
Where and how to store inshell walnuts:
- in the pantry or in the attic of the house, choose a dry, completely protected from light place with a temperature regime of 5-10 degrees;
- a loggia or a glazed balcony are suitable for storage only if they are protected from the penetration of street precipitation and sudden temperature changes;
- in basements, storage is permissible at a humidity of 70% and in the absence of sharp extraneous odors;
- in an apartment, workpieces are stored in places without access to light, away from radiators and heating appliances.
Whole nuts are placed in canvas bags, cardboard or plastic boxes, wooden boxes. The main requirement for containers is cleanliness and absence of foreign odors. The bottom of the boxes is covered with corrugated cardboard and paraffin paper. Boxes are placed on racks, bags are hung. Small volumes can be conveniently placed on the shelves of the upper part of the refrigerator.
Important! Nut moth larvae can cause harm during storage. As a preventive measure, the peeled kernels are heat treated.
The main storage condition is maintaining optimal temperatures without sudden fluctuations.
How to keep at home?
Peeled nuts take up less volume than whole nuts. There is no need to spend extra time to remove the kernels from the shell, they are ready to eat at any time. Let’s see how to properly store peeled walnuts at home, on which to focus special attention.
At the initial stage, it is necessary to sort by removing foreign inclusions. These can be fragments of shells, internal partitions, branches or leaves. We carefully check the peeled kernels for signs of damage caused by pests. All defective nuts must be discarded.
Focus on the smell and color of the product. Fresh kernels should be light and have a characteristic odor, without signs of mold.
If the nuts were purchased on the market, then as a preventive procedure, the entire batch is placed in a slightly salted solution. Next, the kernels are washed with clean water and discarded on a sieve.
Do I need to fry (dry) and why do they do it?
- Pour kernels into a frying pan and, stirring continuously, heat for about a quarter of an hour. It must be remembered that this is not frying, but heating. Avoid browning or scorching of the top coat.
- Lay a layer of kernels 3-4 cm thick on a baking sheet, and ignite in the oven at a temperature of 150 -170 degrees.
Raw materials are allowed to cool and laid out in small batches in prepared containers.
Important! By purchasing walnuts from a reliable manufacturer, you can eliminate the stages of sorting and heat treatment in preparation for storage.
Where to keep?
Considering where the peeled walnuts will have to be stored in the future, they use fabric bags, glass or ceramic jars, and plastic containers for packing:
- if the stock is used up quickly enough, then bags or cardboard boxes will do;
- large volumes are laid out in sterile glass jars and hermetically sealed;
- plastic containers and sealed vacuum packaging are used to store supplies in the refrigerator.
All containers must be washed and dried, and glass containers must be sterilized.
Is freezing effective?
Let’s figure out how to store peeled walnuts in the freezer.
Film bags or plastic containers are suitable as containers. It is desirable that the packaging be airtight. It is important to exclude the penetration of moisture and foreign odors.
Billets are packed in small batches from 200 to 500 g. Repeated freezing is not allowed, therefore the thawed volume must be used completely.
In the low-temperature zone of the refrigerator, the kernels can be stored for up to a year, with practically no loss of quality. After defrosting, they are completely ready for use.
How to store walnuts at home (in shell, peeled)
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 useful qualities. The nuclei contain vitamins A, B1 – B6, C, K, E. And also phosphorus, potassium, magnesium, sulfur, iron, manganese and zinc. They are high in plant protein, fiber and essential oils.
If you eat 2 – 3 fruits a day, you can provide the body with the necessary amount of vitamins and minerals. But you should not get too carried away with the use, especially for people with chronic diseases of the digestive system.
In order for the beneficial substances in the fruits 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 ripe fruits are light in color and have a pleasant, slightly sweet taste.
For conservation, choose full-fledged fruits without signs of mold and the presence of pests.
When a large crop is harvested, the nuts are washed well and dried. But if it is a small batch of fruit, it can be warmed up in a skillet or microwave.
How much walnuts are stored
The shelf life of nuts is determined by the conditions in which they will be located, these are:
- temperature regime,
- degree of humidity,
- illumination parameters,
- the material from which the storage container is made.
Standard conditions for long-term savings are described in GOST:
- temperature from -15 ° С (exactly minus 15) to + 20 ° С (without sudden jumps);
- humidity – up to 70%.
Such indicators are optimal for storing nuts for up to 1 year, and their kernels – up to 6 months.
- In a cold place (at a temperature of about zero), and high humidity , the shelf life of walnuts does not exceed 6 months. Frozen fruits will be usable 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, closed from light, 10-18 months.
- Peeled 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 package. If stored this way, they will suffocate and become unusable.
Storing nuts in shell
- When sending the fruits for storage, they are pre-dried. Excessive moisture will quickly lead to rotting and the development of mold.
- The rest of the peel is removed.
- When there are many fruits, they are dried in the fresh air in clear weather. But for these purposes, a ventilated balcony, as well as an attic room, is also suitable. Nuts are placed on newspapers in one layer (cloth can be used). Then regularly turn them over every 2 – 3 days for even drying.
- Drying in the oven at +60 – + 65 ° C is a more effective method. Oven baking will also kill the pest larvae. At this temperature, keep the fruits in the oven for at least 2 hours. They are also often dried in metal containers on a hot battery.
Experienced housewives believe that proper storage of walnuts as a whole occurs at a temperature of -5 ° C – + 10 ° C.
The fruits should be kept at low humidity, especially if they are in cloth bags.
It is unacceptable to keep the crop in the sun. When the nuts are in a glass container on the balcony, you need to cover them with something. Better to hide it on the shelf of a closed built-in cabinet.
When exposed to high temperatures, a significant part of the vitamins is destroyed. The taste becomes bitter due to changes in the structure of the oils, which are present in large quantities in the kernels.
The container in which walnuts are best stored may be:
The bottom of the box is covered with corrugated cardboard or wax paper. Storage of walnuts in wooden containers takes place on shelves, and if the fruits are in bags, they are hung.
Rules for choosing a peeled walnut
By purchasing walnut kernels, you can immediately see the product, which is good on the one hand. But the shelf life of kernels is less than that of whole fruits. Therefore, you will not be able to store peeled walnuts for a long time.
Freshly cleaned product has a presentable appearance, without dark spots and marks of vital activity of insects. It is important that the kernels are the same color. This is an indicator that all kernels are from the same batch, and the seller has not mixed stale goods with them.
It is not worth buying an already crushed refined product: no one can guarantee the quality of the feedstock.
You cannot buy kernels in spontaneous markets located right on the road. They are very good at absorbing dust and car exhaust fumes. On their surface can be various harmful bacteria and even E. coli. It would be pointless to talk about the useful qualities of such a product.
Before buying, be sure to try what you intend to buy. The slightest taste of bitterness, or a musty unpleasant smell should deter you from purchasing this product.
The walnut, peeled from the 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 a humidity not exceeding 70%.
Storing peeled walnuts in a plastic container is not permissible: they will quickly become covered with mold and rot due to lack of air access.
At room temperature, storing walnut kernels will only take 2 months. To avoid the appearance of moth larvae, the kernels should be fried in a skillet. You can also heat food by placing it in the oven.
Freezing peeled walnuts
- The kernels are placed in bags in small portions, well closed and frozen.
- Before use, they can be fried in a skillet, or it is easier to reheat them using the microwave.
- Green (not ripe) walnuts can be stored for up to 7 days at + 10 ° C – + 20 ° C, after which they are processed (as a remedy).
How to store walnuts – optimal conditions and acceptable terms | My kitchen
Sun kernels are one of the favorite delicacies. Luxurious filler for homemade baked goods, be it cakes or pastries. They were sung by poets and whole treatises by alchemists dedicated. Our article is much more prosaic, but, we hope, no less useful, we will tell you how to preserve this wonderful delicacy.
Storing walnuts at home
It is not in vain that nature hid the delicate tasty kernels of nuts in a hard shell; there are plenty of hunters to feast on them in the wild.
As soon as man tasted these gifts of nature, the tailed nut lovers had a serious rival.
Nuts, like other gifts, were initially harvested as needed, but as civilization developed, people learned to grow them, yields became significant and supplies, too, immediately the question arose of how to properly store walnuts.
It probably took a little time for the ancient people to understand that simply dumping the nuts in the corner of the cave would not save them for a long time. The nuts in the shell took up a lot of space, and the shell itself could come in handy as a reserve of fuel. Pretty soon the problem began to sound a little different: how to store peeled walnuts so that they retain their qualities longer and take up a minimum of space.
Having learned to use fire, humanity has made a giant step in its development. More significant, perhaps, has not happened since then.
In addition to heating homes, the diet of our ancestors immediately changed, this affected not only the everyday table, but, of course, the blanks.
The storage of walnuts became longer; they began to dry them before laying them for the winter, and the conditions in the dwellings became drier.
Everything that we are writing about so far is just speculation, but the real story is unlikely to be too different.
A successful year fell out and a great harvest turned out, the knowledge of how to properly store peeled walnuts came in handy right there.
The squad moved to the north, set up a border blockhouse, and the same nuts were poured into the bins, but not chopped. In a word, the technology for storing food, including nuts, has evolved literally with every human step.
From a historical background, we will move on to practice, and we will study how to properly store nuts at home, observing all the experience accumulated by our ancestors. Storage of harvested nuts, with the exception of an industrial scale, is carried out mainly in the following ways:
- In the shell, peeled.
- In the shell, unpeeled.
- Chipped and disassembled into nuclei.
- Disassembled and crushed.
Let’s break the order of the list and start the story about how to store nuts at home from point two. It is rarely used and is rather used for temporary storage, before further processing.
The conditions with this method are perhaps the most costly: the nuts are stored spread out in one layer over a large space. Installation of a canopy is required as the dates for harvesting delicious nuts often coincide with the onset of rainy weather.
The shelf life is short, as soon as possible it is worth cleaning the nuts from the remnants of the dried peel and additionally processing it with one of the accepted methods.
A longer shelf life is provided by such a method, for example, how to store walnuts in the shell. It deserves special attention, and will be considered in detail, but at the beginning we will give only a general description.
As they are harvested, the nuts are immediately peeled from the easily peeling outer skin and laid out for airing. In sunny weather, under hot rays, this process takes place relatively quickly. Then the nuts can be cracked, but more often they are first heated and dried. This can be done in the oven or in a skillet if the amount is relatively small. Dry them at home and on hot batteries.
Technologies for parsing nuts into kernels and shells deserve a separate article, but for now we are only talking about ways of storing nuts correctly. We will only mention that it is not always worth striving to obtain whole kernels, since for most cases of further use of nut kernels this is unnecessary.
After the shell is removed, you will have two more options to choose from: immediately pack the nuts into small containers for storage or pre-fry them.
The first method is preferable, since nuts are not always used in cooking roasted.
The second is more often used before pouring the nuts with honey, adding to the jam, and it does not fully respond to the topic of how to store peeled walnuts at home.
How to store walnuts at home
Having described the general principles, we will consider how to act in case you need to save small batches of nuts for the household, on the order of units or several tens of kilograms. One or several trees from the garden area may well provide you with such a crop.
Let us first discuss storing inshell walnuts, since this method is not so demanding on conditions, although it is designed for a larger room volume. In this way, nuts can be stored even in a country house and it is not necessary to transfer them to a city apartment.
How to properly store inshell walnuts
Start by cleaning properly. The fruits are covered with a strong shell, but it is still undesirable to knock them off the branches with sticks or pick them from the ground after a long period of lying.
Even minimal damage greatly affects how long walnuts are stored in the shell.
It is customary to sort them immediately, putting aside cracked and stale ones in order to remove the shell and either quickly use it or store it already in a split form.
Dry the nuts before storing them. It is enough just to dry them out, protecting them from the weather, but after exposing them to a short calcination, the shelf life is extended by several months.
It is important to observe the temperature regime, humidity and air flow in the storage room.
It is believed that properly prepared nuts are stored for up to a year if the temperature is in the range from -12 to +20 degrees and does not change abruptly.
Recommended humidity up to 72%, no sunlight. Storage containers are preferable from natural materials – hemp bags, veneer or wood boxes, nets made of natural threads.
We do not consider the above-mentioned method of storing nuts without removing the outer peel, since it is better to store peeled or inshell walnuts, and this is a well-known fact.
How to properly store shelled walnuts at home
By removing the hard shell, you not only reduce the volume occupied by the stock of treats, you also open up previously inaccessible opportunities. So, for example, there is no better way than to keep the walnuts frozen. They will take up little space, and the shelf life will grow to an incredible 15-18 months.
Having split the shell, the kernels removed from it are sorted, getting rid of the spoiled ones. It is worth sorting them right away by size, separating small, but inevitable crumbs. You should not throw them away, because the size of the pieces depends on the prepared dish or baked goods and it may turn out that the halves of the kernels subsequently have to be finely chopped.
The presence of a backyard shed with a temperature above +10 degrees removes the problem with the room, but how to store peeled walnuts at home in an apartment if you do not intend to freeze them?
A convenient place will be a loggia closed from the street weather. Nuts are sorted and packed in glass containers or bags with tight fasteners, then stored, trying not to expose to the sun and avoiding sudden temperature fluctuations. A regular cabinet or a drawer covered with a canvas is suitable for these purposes.
A home pantry or mezzanine is also a good place. Before storing peeled nuts in these places, just make sure that the temperature does not exceed the recommended 20-23 degrees. The fact is that mezzanines are often arranged at the entrance to the kitchen and hot air when cooking food can negatively affect the shelf life of nuts.
To save cracked nuts from spoilage, they are often fried or heated in the oven. Such actions do not increase the duration of storage, and in some cases, on the contrary, reduce the time. Use them only in cases where you will definitely use up the roasted nuts in the next month or another.
The degree of roasting dictates rather your own taste, but keep in mind that the oil released from the kernels over time, upon contact with open air, can turn rancid and spoil the taste of the nuts.
The following storage method is not entirely relevant to the topic of the article, but it is worth mentioning it at least because of its popularity. We are talking about a kind of natural canning, in which the nucleoli, peeled from the shell and film, are fried and then poured with natural honey.
If you do not need the nuts as a filling in baked goods or desserts, brown them and cover with honey. Cork the jars with plastic lids and put them on the balcony. The temperature at which such an unusual piece will be stored should be only slightly lower than the recommended temperature for storing pure honey.
If you stock up on nuts for the winter not based on specific recipes, but for the sake of the benefits of the trace elements they contain, there is no better way.
Walnut is called one of the healthiest foods for humans. Consuming walnuts in a reasonable amount is a wonderful and tasty way to maintain your health in excellent condition and saturate the body with the necessary proportion of nutrients. So that the usefulness of the fruit does not disappear after collection, it is important to know how to store the nuts.
How to choose the right walnuts for storage
Ripe walnuts do not change their chemical composition over time. Taste and useful properties are not lost. The main thing is to prevent rotting, which requires compliance with all storage conditions at home. To preserve the usefulness and taste, it is not only the stage of proper storage that is important, but also the choice of a good fruit. When buying, follow the rules:
- The age of the fetus after collection should not exceed 3 months. Unlike freshly harvested nuts, last year’s shells will be dirtier or darker in color.
- The nut shell should be dense, without cracks or chips. Otherwise, even through small cracks, moisture will get inside and the fruit will deteriorate.
- The appearance of the shell and the taste of the fruit itself are important. Therefore, you should try several kernels (they should not be bitter, but, on the contrary, have a sweetish taste).
- To determine a high-quality tasty fruit, you should take the nut in your hand, shake it several times. No sound will be heard when shaking a good nut. If in the shell it is felt as if there is a small ball inside and the nut is lightweight, then the kernel inside is dry or deteriorated, so you should not take it.
After purchasing or collecting nuts, perform one more step – prepare them for storage at home. First, you should rinse the nuts in a colander.
This will clean the shells of dust and dirt that got on them during transportation. Secondly, after washing, the nuts must be well dried.
This can be done by laying out the fruits on any horizontal surface, where there is no dampness and there is a possibility of airing (it is possible in the open air).
Thirdly, when stored without a shell, the nucleoli should be separated from the partitions, leaving only a clean fruit without various fragments or debris.
Features, place and storage time
Storing walnuts at home is very convenient. The fruit, rich in vitamins, is used in cooking, as well as as an independent product. For the preservation of the product, it is necessary to observe the conditions of humidity and storage temperature. Also, the container and the storage location affect the shelf life, and then whether a whole nut is stored or peeled.
The temperature at which the nuts are stored is important. It should vary from -15 to +20 and, most importantly, sudden changes or temperature jumps are unacceptable. Air humidity should not be more than 70%.
What matters is the packaging and location of the nuts. In order to properly store a walnut in its shell, the fruit is placed in fabric bags, cardboard, plastic or wooden boxes, the bottom of which is lined with foil or paper. You can store such nuts in attics, storerooms or basements, on closed balconies (without rainfall), in an apartment.
You can store peeled walnuts at home in fabric bags or cardboard boxes. For a longer preservation, the grains are placed in a glass container and tightly corked. Sealed or vacuum containers are used if storage is supposed to be in the refrigerator or freezer compartments.
Remember! Walnuts should not be stored in plastic bags. This will lead to rapid deterioration and rotting of the product.
The storage conditions for nuts are:
- clean packaging free of any odors;
- lack of large temperature differences;
- the darkness of the room without the ingress of a large amount of sunlight;
- should not be stored next to batteries or any other heating device.
How long walnuts should be stored at home
The storage time depends on a number of conditions. For example, if temperature and humidity are observed, the shelf life of inshell walnuts reaches 12 months, and kernels – up to six months. If the peeled walnut is placed in the refrigerator, then it can be consumed within 6 months, and when stored in the freezer, the period increases to 1 year.
Room temperature will shorten the storage time. Whole fruit in shell, placed in a canvas bag, can be stored for six months, and in glass without light – 10 months. When storing peeled kernels, the periods are reduced. In glass or plastic containers – up to three months. In fabric bags – up to two months.
Ways to increase the shelf life of walnuts
The shelf life can be increased. Then the fruits will be suitable for consumption longer.
After collecting or buying nuts, you need to split them and separate the kernels from partitions, shells and other husks. Next, put the nuts on a baking sheet and put in the oven for 45 minutes.
After that, the nuts are cooled and placed in a suitable container. To preserve the taste and benefits of walnuts for as long as possible, fried kernels are stored in the refrigerator in an airtight container.
This storage extends the shelf life of the shelled walnuts up to 6 months.
Important! Roasting and roasting the kernels of the nuts helps to get rid of all kinds of larvae or pests that have got inside the nut.
Freezing walnuts for storage
To preserve the taste and nutrients of the shelled kernels for a year, they should be kept in the freezer compartment.
Proper freezing is as follows:
- thoroughly remove all husks;
- put in a plastic bag so that the nuts fit exactly in one layer;
