There are several ways to store walnuts in shells:
Drying treatment: Before storage, gently wipe the surface of the walnuts with a clean damp cloth to remove dirt and impurities, then place them in a well-ventilated place to dry, and ensure that the walnuts are completely dry. This can prevent insects from breeding in a humid environment.
Low temperature storage: Put the dried walnuts in a sealed bag or sealed can, squeeze out the air, and reduce contact with the outside air. You can put food desiccant or bamboo charcoal bags in a sealed container to absorb moisture. If conditions permit, walnuts can be stored in the refrigerator or freezer. Low temperature can prevent the hatching of insect eggs and the growth of insects.
Refrigerated storage: Put the walnuts in a sealed container, ensure that the container has good sealing performance, and store it in the refrigerator's cold storage room. The temperature is kept between 2 and 8 degrees Celsius. This can effectively extend the shelf life of walnuts while maintaining their freshness and taste.
Frozen storage: Put the processed walnuts into a food-specific sealed bag, squeeze out the air or vacuum it, and then put it in the freezer of the refrigerator, set the temperature to below 0-4 degrees. Frozen walnuts can be stored for many months. Although the taste will change slightly, it is still good overall.
Precautions for storing shelled walnuts:
Regular inspection: Check the stored walnuts every once in a while to see if there are signs of insects. If you find that some walnuts are infested with insects, be sure to separate them from other walnuts immediately to avoid the spread of insects.
Prevent odor: Make sure the walnuts are completely dry and sealed before putting them in the refrigerator to prevent them from absorbing odors in the refrigerator.
