The walnut is often referred to as the "tree of life". Indeed, thanks to its rich composition, it satisfies hunger, restores strength, and treats almost any disease.
It is enough to eat three nuts a day so that the body receives as many useful trace elements as necessary to maintain health and strong immunity.
But for this it is necessary to stock up on nuts for future use in the fall, while they are fresh and not spoiled by improper storage.
After all, it is not enough to collect them, you also need to save them until the next harvest.
It is very good if you have your own walnut tree.
Many housewives prefer to buy nuts without shells. Because, firstly, it is convenient, since you do not need to spend your precious time cracking hard shells and extracting nuclei.
Secondly, unlike whole walnuts, which everyone buys like a "pig in a poke", shelled nuts can be seen, smelled and tasted, thereby determining their quality.
Festive video recipe:
Green nuts are not subject to storage. Most often they are used for medicinal purposes. To do this, they are immediately processed.
All these methods of storing walnuts are easily implemented both in a private house and in a city apartment. The main thing is to buy high-quality nuts.
The walnut tree, or, as it is also called, royal, has a high yield. The fruit of the culture is an indehiscent bone, in a woody shell of which an edible core is enclosed. This is a real source of health, a gift from nature. Up to 25 kg can be harvested annually from one adult tree. To keep a valuable product fresh for a long time, it is important to know where and how to store walnuts.
An important factor that ensures the integrity of the product is the period of maturity. In September - early October, the nut ripens and falls from the tree. The amniotic green peel dries up, bursts into several parts, separating from the bone. The natural shell protects the shell from exposure to ultraviolet rays and oxygen. If the fruit is plucked from the branch and cleaned of greenery on its own, there is a rapid loss of moisture, which leads to disruption of ripening processes.
The oily core contains up to 77% fatty acids:
It is because of the high percentage of fat that the conditions and location must be taken seriously, otherwise the storage period will not last up to a year.
The main reasons for poor quality and spoilage of the product are unsatisfactory indoor conditions, Where is the walnut stored?
If the royal tree does not grow in the yard, useful fruits can be bought. To assess the quality of the product, it is better to purchase a peeled nut. In addition, you do not have to spend time splitting a hard bone. It is not known where and how long the walnuts were stored in the shell before being sold, so light, whole halves are chosen. The dark skin color indicates heat treatment. Too dried slices lose most of the vitamins and nutrients. But such a choice is not suitable for creating strategic reserves. and the cost of the peeled fruit is high.
Stock up if needed nutritious food for the entire winter period, then the nut in the shell is purchased. It should be dry, but not overdried, without a thick green peel. The year of harvest is determined by color: golden or even brown - this year's harvest, darker - last year's. Fruits should be approximately the same variety and size. The presence of any damage, white bloom or spots on the surface of the wood shell indicates a poor-quality product.
Weighing in the hand helps determine the integrity of the edible kernel. A good nut will be significantly heavier than one with a dried core. If you shake it, then by the characteristic knock you can understand that the core is overdried . Purchased nuts before consumption is recommended rinse thoroughly with warm water. After splitting, separate the edible core and ignite in a pan for about an hour over low heat.
It is better to buy large quantities in the fall, since it is at this time that the harvest takes place. So that the purchased product does not deteriorate at home, you need to know how much you can store walnuts in the shell and without it.
Saving a large number of nuts until spring is not at all easy. Rich harvests or large purchases will quickly become worthless if favorable conditions are not created. The key to successful storage is the correct temperature regime and regular monitoring of the state of stocks.
O useful properties ah hard fruit known for a long time. It is used in fresh, from which they prepare medicinal tinctures. The oil is famous for its amazing amber hue and rich aroma. . Integers are widely used and crushed kernels in the culinary business. Given the different uses, nuts can be stored in three ways:
The first method is the most preferable, since low-quality bones will be removed immediately. This saves space and prevents the spread of pathogenic bacteria.
It is possible to correctly crack the shell without damaging the core by the method of short-term exposure to high temperatures. Required amount of nuts placed in an enamel bowl and poured with boiling water. After 10 minutes, the liquid is drained. With a knife, the hard shell is easily split. You can use a nutcracker or a hammer, but keeping the kernels whole will be much more difficult.
The thickness of the shell is easily checked upon purchase. You need to take two nuts and press them in the palm of your hand. If the bone cracks, then there will be no special problems when cleaning.
A little space is taken up by chopped nuts. The method is also convenient because you can pre-make blanks for future dishes. But the mashed nut does not store well. In this form, it should not be bought in stores and trade pavilions. It is better to do this process yourself. How to grind walnuts at home:
Deep freezing extends shelf life crushed nuts. They are divided into portions, poured into special bags and placed in the freezer. Due to the high oil content, they defrost quickly. The product is ready for use in 15 minutes.
If there are many fruits, linen bags are used. They must be stored hanging in a dark, cool room. This ensures free access of air from all sides. Periodically, the contents of the bag are examined, dried as necessary.
Nuts stored in wooden boxes do not lose their useful properties. They are placed in a room with minimal humidity and no foreign odors. Nuts are stacked in layers, between which a canvas fabric is stretched. Canvas perfectly passes air, does not absorb water. Moisture formed in any of the layers, thanks to the dense fabric, will not spread through the box. It is not recommended to pour the fruits into a plastic bag. Due to the lack of air, they will lose their taste and smell. If you follow all the rules, the shelf life of walnuts in the shell can be increased to two years.
To prevent shelled walnuts from spoiling, several sequential steps must be followed. The kernels are sorted out, completely cleaned of hard peel and partitions. The remains of the shell accelerate the process of reproduction of fungi, so they must be carefully removed. Nuts are placed in a plastic or glass container, which is hermetically sealed. The container is placed in a cool, dry place at a temperature of +5 to +10 C°. Small containers can be stored in the refrigerator.
During long-term storage, the peeled kernels can be damaged by insects. In this case, the fruits are washed well, then dried in the oven for 10 minutes. Warming reduces the amount of nutrients, but it is the most effective pest control method. Fatty oil in fried halves is released faster, so the shelf life is short - up to 2 weeks.
Honey has good antiseptic properties. Nuts immersed in a bee product are the most useful storage method. Fulfillment of all conditions will allow you to save generous harvests of royal wood, as well as enjoy a tasty and safe nut all year round.
Attention, only TODAY!
The properties of walnuts have long been known. 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. As well as phosphorus, potassium, magnesium, sulfur, iron, manganese and zinc. They are rich in vegetable protein, fiber and essential oils. If you eat 2-3 fruits a day, you can provide the amount of vitamins and minerals the body needs. 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 nutrients 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.
The fruits of the correct form, 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 aftertaste.
For saving, choose full-weight fruits without signs of mold and the presence of pests.
When a large crop is harvested, the nuts are well washed and dried. But if this is a small batch of fruits, it can be heated in a skillet or in the microwave.
The shelf life of nuts is determined by the conditions in which they will be, these are:
Standard conditions for long-term savings are described in GOST:
Such indicators are optimal for storing nuts for up to 1 year, and their kernels for up to 6 months.
(function(w, d, n, s, t) ( w[n] = w[n] || ; w[n].push(function() ( Ya.Context.AdvManager.render(( blockId: "R-A -321160-3", renderTo: "yandex_rtb_R-A-321160-3", async: true )); )); t = d.getElementsByTagName("script"); s = d.createElement("script"); s .type = "text/javascript"; s.src = "//an.yandex.ru/system/context.js"; s.async = true; t.parentNode.insertBefore(s, t); ))(this , this.document, "yandexContextAsyncCallbacks");
Experienced housewives believe that the proper storage of walnuts as a whole occurs at a temperature of -5 ° C - + 10 ° C. Fruits should be 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. And it is better to hide 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 a change in the structure of the oils that are present in large quantities in the kernels.
The container in which it is best to store walnuts can be:
The bottom of the box is covered with corrugated cardboard or wax paper. Storage of walnuts in wooden containers takes place on racks, and if the fruits are in bags, they are hung up.
When purchasing walnut kernels, you can immediately see the product, which, on the one hand, is good. But the shelf life of the kernels is less than that of whole fruits. Therefore, it will not work for a long time to store a peeled walnut.
A fresh, cleaned product has a presentable appearance, without dark spots and insect marks. 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 with them.
It is not worth buying an already crushed purified product: no one can guarantee the quality of the feedstock.
In spontaneous markets located right next to the roadway, you can’t buy cores either. They very well absorb dust and exhaust gases of cars. On their surface, various harmful bacteria and even E. coli can be found. O useful qualities it would be pointless to talk about such a product.
Before buying, be sure to try what you are going to buy. The slightest taste of bitterness, or musty bad smell should keep you from buying this product.
The nut, peeled from the shell and partitions, is kept at a low temperature in tightly closed glass or metal containers. They should be isolated from sunlight and kept in places with humidity not exceeding 70%.
Storage of peeled walnuts in plastic containers is not permissible: they will quickly become covered with mold and begin to rot due to lack of air.
At room temperature, walnut kernels can be stored for only 2 months. To avoid the appearance of moth larvae, the kernels should be fried in a pan. You can also ignite foods by placing them in the oven.
The kernels are placed in small portions in bags, well closed and frozen.
Before use, they can be fried in a pan, or it is easier to warm them up with a microwave.
Green (unripe) walnuts can be stored for up to 7 days at +10°C - +20°C, after which they are processed (as a remedy).
In the presence of high-quality raw materials, storing walnuts is not difficult. And this product should be in the diet all year round.
Consider the question of how to store peeled walnuts at home. What methods allow you to increase the shelf life without affecting the composition of the product? What role does heat treatment play and is it possible to do without it?
Let's compare the difference between storing whole and shelled walnuts.

Classmates
- a valuable product with a unique composition of mineral waters and vitamins, a specific set of aromatic and tannins. A high proportion of 18 to 21% is protein. Depending on the variety, from 45 to 77% is fatty nut oil, which contains a unique set of saturated and unsaturated acids. Chemical composition varies 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 complete set of substances that may be required for the development of a new plant.
Under the shell, a microclimate is created that can protect the kernel from external influences for a long time. It is not difficult to understand how to store walnuts in the shell at home. It is necessary to observe the balance of temperature and humidity, the mode of limited illumination.
If the nut is cleaned and not protected by a strong bone shell, then the influence of external factors increases. Therefore, conditions are created under which all chemical processes slow down, which involve:
With strict observance of the regimes, you can store the product for up to a year with virtually no loss of quality.
Useful properties of walnuts
The 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.
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 the 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.
For long-term storage, medium and large, undamaged specimens are selected, with a thin but strong shell. Ripe nuts are distinguished by a high oil content, a pleasant, sweetish taste, without excessive astringency and bitterness. The skin covering the kernel should be light in color.
Full-weight fruits are selected, without signs of damage or cracking. The shell should not show signs of mold or pest infestation. When harvesting in industrial quantities, the raw materials are washed and dried. At home, small batches are enough to warm up in the oven or in a pan.
Where and how to store walnuts in the shell:
Whole nuts are laid out in canvas bags, cardboard or plastic boxes, wooden boxes. The main requirement for the container is cleanliness and the absence of foreign odors. The bottom of the boxes is covered with corrugated cardboard and paraffin paper. The boxes are placed on racks, the bags are hung. Small volumes are conveniently placed on the shelves on top of the refrigerator.
Important! Damage during storage can be caused by nut moth larvae. As preventive measures peeled kernels are subjected to heat treatment.
The main storage condition is to maintain optimal temperatures without sharp fluctuations.
Peeled nuts take up less volume than whole nuts. No extra time is needed to extract the kernels from the shell, they are ready to use at any time. Let's see how to properly store peeled walnuts at home, what to focus on.
At the initial stage, it is necessary to sort by removing foreign inclusions. These can be fragments of the shell, internal partitions, branches or leaves. We carefully check the peeled kernels for signs of damage caused by pests. All defective nuts are subject to culling.
Pay attention to the smell and color of the product. Fresh kernels should be light in color and have a characteristic odor, with no 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 thrown back on a sieve.
The kernels that have been sorted are subjected to drying in order to destroy the larvae of pests, fungal spores, and to evaporate excess condensate and moisture. It is hard to imagine how to preserve shelled walnuts at home without heat treatment. The process is quite simple, but it significantly affects the quality of the product. Heat treatment is carried out in one of the ways.
The 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.
Considering where the peeled walnuts will have to be stored in the future, fabric bags, glass or ceramic jars, plastic containers are used for packaging:
All containers must be washed and dried, and glass containers sterilized.
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 is airtight. It is important to exclude the penetration of moisture and foreign odors.
The blanks are packed in small batches from 200 to 500 g. Re-freezing is not allowed, so the thawed volume must be used in full.
In the low-temperature zone of the refrigerator, the kernels can be stored for up to a year, with virtually no loss of quality. After thawing, they are completely ready for use.
Before use, having bought peeled walnuts on the market, carry out the mandatory processing procedure:
Knowing how to properly store walnuts without shells and comparing the various options, we can draw the following conclusions.
The most suitable place in a house or apartment is a freezer or a food zone of a refrigerator.
The advantages of this method are stable conditions:
This method is ideal for long-term and safe storage.
The disadvantages include the lack of space when storing large batches.
