Walnut kernels are delicious, but storing them can be both simple and a bit tricky.
Fresh walnuts (wet walnuts): 15 days.
Walnut kernels: 6 months.
Dried walnuts: 10 months in the fridge.
First, keep the following in mind:
1. Try to store them in a well-ventilated place.
2. Don't use sealed bags.
3. Use cloth bags, burlap sacks, or other bags that allow good airflow.
Why use bags with good ventilation? Because this helps prevent the walnuts from being too moist. Ventilated bags quickly release moisture, it will keep the walnuts dry, and prevent them from becoming damp or moldy.
It's pretty easy to tell if walnut kernels are expired. Fresh walnut meat is a light yellow or pale amber color-the darker the color, the older the walnuts. You can also smell them to check if they're still fresh and edible, kind of like peanuts. If they smell rancid, it means they've gone bad and shouldn't be eaten. Bad walnuts can have dark spots, oil seeping out on the surface, and some might even grow mold.
When storing walnuts, the first requirement is to dry them (the standard for drying is that the membrane inside easily breaks when pinched). At room temperature, they can be stored for a year. For longer storage, put them in a plastic bag and keep them in a place around 5℃, with dry air and no direct sunlight. You can also store them in the fridge.
The shelf life of walnuts generally ranges from six months to a year, depending on factors like the condition of the walnuts themselves and the storage environment. In general, walnuts that are well-dried and properly stored can last about a year. If the walnuts are only moderately dried and the storage conditions aren't great, they may only last six months or even less. The above refers to walnuts with shells; if it's shelled walnut kernels, the storage time is shorter, generally three to six months at most.
Raw walnuts can be stored for six months to a year, preferably in a dry and ventilated place. You can also put raw walnuts in a resealable bag and store them in the fridge to keep them fresh, which helps prevent them from going bad. Raw walnuts are freshly picked from the tree and haven't undergone any processing, making their taste more delicious than regular walnuts. Raw walnuts are very nutritious, rich in protein, and consuming them in moderation is beneficial to your health.
Walnuts contain lysine, which is really good for brain health, so the saying that walnuts help with brain power actually makes some sense. Besides, walnuts can also help slow down aging, nourish the skin, and are good for the heart. In daily life, we can buy some walnuts with shells; whether eaten with main meals or as a snack, they're a great choice. Knowing about the shelf life of walnuts helps us store them better and ensures they don't go bad or lose their flavor.
The best way to store walnut method is deep processing for walnut.
