When ripening, a walnut loses its green shell - the shell. It is not recommended to collect fruits until they lose their protective structure on their own. It helps protect against the early harmful effects of sunlight and oxygen.

When clearing greens early, light and air begin to dry out the wood peel, and at the same time, some of the nutritional properties evaporate from the kernel, and some vitamins contained in the product are also destroyed. At the same time, with timely removal of the peel (using natural forces), the kernel completely retains all the useful elements accumulated during the period of formation and ripening in the green shell. When it is lost, the core gradually begins to lose moisture, at which point the maximum concentration of all 80 elements occurs.

Storing nuts without shells: methods and rules

If the nuts have been peeled, they will be more difficult to preserve. The best option will place the kernels in a tightly sealed container, in a plastic bag or cling foil. Then they need to be placed in the refrigerator in the vegetable department or in the freezer. It is recommended to place the entire supply in the freezer not in one bag, but in different ones. This way it is better to defrost and use for consumption. But at the same time, some of the nutrients evaporate, and the nuts will lose their taste.

Another storage method is exposure to high temperatures.

With this processing method, insect larvae or their eggs laid inside the kernels are neutralized. The procedure is carried out either in a frying pan or using an oven. But with such an impact, a partial loss of beneficial qualities inevitably occurs.

Safety rules:

Do not leave it for a long period of time without placing it in the refrigerator.
Keeping it in a plastic bag for several days is not recommended - the kernels lose their taste and quality (spoil). This occurs due to lack of air.
Do not store peeled fruits in a humid atmosphere. They become saturated with water, become rotten, and mold forms on them.
If mold stains appear, you should not save the product - it is completely filled with toxins.

Thus, you need to store it not just by peeling the kernels from the shell on a plate, but in containers specially prepared for this.

If the fruits were collected at the appropriate time, when the green shell opened on its own and the kernels fell out or were knocked down by the wind, then storage is possible for 2 years. But, in this case, the kernels must be thoroughly dried and not separated from the wood peel.

If the product was collected early, in a natural shell, then its preservation will be short-lived - the peel will turn black, affecting the inside. The storage period will not reach 1 year.

The duration of storage of unshelled nuts does not exceed 1 month; in case of good packaging, the period can increase to 9-12 months.

When the peeled kernels are placed in a 3-liter jar, which is tightly closed with a lid, the period of use can reach up to 5-6 months, especially if it is placed in a dark, dry and cool place. If you plan to store it for a short time, you can hang the unpeeled nuts in a bag or put them in wooden boxes.
