Quality and delicious walnut is usually understood from its thin shell. If you are buying shelled walnuts, make sure that the shell is not broken. Make sure that the walnut is not mouldy and look carefully at its colour. If you smell old oil when you open it, this is an indication that the walnut is not fresh. Make sure that the walnut is dry and not damp. If you are buying packaged walnuts, make sure that the package is not open and has production and expiry dates.
Under which conditions should walnuts be stored?
Storing walnuts in a cool, dark, dry place and in an airtight closed container without breaking the shell extends their life. They can be stored in the refrigerator at 4-5 degrees Celsius or in the freezer below 0 degrees Celsius for 1 year. If you want to store them at room temperature, the microorganisms can be killed if you first freeze them at -18 degrees Celsius for 48 hours. Walnuts exposed to heat for a long time can harden. This causes the walnut to have a bitter taste. In addition, walnut is a food that attracts odour easily. For this reason, it is recommended not to keep it in the same place with odorous foods. If it looks too wrinkled, it means that the walnut is spoilt.
Does Bacteria Occur in Walnut?
When wet walnuts are kept in a closed container, mould is seen. This causes various microorganisms to be taken into the body. Therefore, fresh walnuts should be consumed quickly. Dried walnuts should be kept in a tightly closed container. Again, if the walnuts are not dried correctly, they can become mouldy. Therefore, bacteria may occur in walnuts.
How should walnut be consumed?
Breaking the walnut when you consume it allows you to eat fresher. In addition, the formation of bacteria on it is prevented in this way. You can consume walnuts alone or you can eat them with your salads, foods such as hummus, healthy breads, sauces such as pesto, smoothies and soups. Instead of roasting walnuts in oil, consume them raw or roasted without oil. Put 2 walnuts in a glass of water at night and eat these walnuts in the morning. Wet walnuts are both easier to digest and more easily absorbed as phytic acid will decrease. The benefits of walnuts in water are also like normal walnuts.
Is Walnut Juice Useful?

Harm of Walnut
Walnut can have benefits as well as harms. Excessive walnut consumption can cause kidney stones due to oxalate content. Walnuts can also be risky for allergic bodies.

Excessive walnut consumption may cause diarrhoea and nausea. This is an issue that should be more careful especially in people with irritable bowel syndrome (IBS).
It can be dangerous for children to consume such foods because they can get into the throat.
