Walnuts are a favorite snack for many people around the world. They are not only tasty but also rich in nutrients and good for the body. However, like all foods, walnuts come with an expiration date, and you need to take good care of them to keep them fresh for as long as possible. In this article, we will discuss how to store walnut kernels and keep them fresh.
1. Keep them cool
The first and most crucial thing you need to keep in mind when storing walnuts is to keep them cool. Walnuts are sensitive to heat, and exposing them to high temperatures can cause rancidity, making them spoil quickly. Therefore, store your walnuts in a cool and dry place that is away from sunlight, such as a pantry or cupboard.
2. Store them in an airtight container
Another essential step in storing walnut kernels is to store them in an airtight container. Exposure to air can also cause rancidity, making them spoil. Airtight containers like glass jars, plastic containers, or zip-top bags can prevent air from affecting your walnuts' quality.
3. Keep them dry
Besides keeping them cool and in an airtight container, you should also ensure that your walnuts remain dry. Moisture can breed mold and bacteria, causing your walnuts to spoil quickly. When storing your walnuts, ensure that the container is dry and the walnuts are dry too. If your walnuts are moist, use a paper towel to dry them first before storing them.
4. Take note of the expiration date
Walnuts also have an expiration date like every other food item you purchase. Therefore, ensure that you check the expiration date before purchasing them and plan to consume them before they expire. If you have walnuts that are approaching their expiration date and you are not ready to eat them, consider freezing them to keep them fresh for a longer duration.
5. Store them in the freezer
The best way to keep your walnuts fresh for a more extended period is to store them in the freezer. Freezing walnuts can keep them fresh for up to a year or more. To freeze your walnuts, ensure they are dry first, then place them in a zip-top bag or airtight container and store them in the freezer.
6. Consider roasting your walnuts
Roasting walnuts is also an excellent way to preserve their quality and make them taste better. Roasting walnuts helps to remove excess moisture, making them crisp and delicious. Roasted walnuts can last for a longer duration, and you can store them in an airtight container or the freezer.
7. Take caution when storing shelled walnuts
Storing shelled walnuts is a bit trickier than unshelled walnuts. When you remove the shells, nuts tend to spoil quickly because their protective shell is no longer there. Shelled walnuts can spoil in as little as three to four weeks, so ensure to store them in an airtight container and in the fridge or freezer to keep them fresh for a more extended period.
In conclusion, taking good care of your walnuts is essential to keep them fresh and maintain their quality. By following the tips mentioned above, you can store your walnut kernels for an extended period and enjoy them as a tasty and healthy snack.
