How To Properly Store Walnuts

Why Is It Important to Store Walnuts Properly?

Walnuts are primarily grown in the Mediterranean region, where the climate is ideal for their development. When imported from the U.S. to Vietnam, changes in temperature and climate can easily cause walnuts to spoil. This is especially true for naturally harvested walnuts that have not been processed, which tend to spoil faster if left untreated.

Several factors contribute to the deterioration and quality loss of walnuts:

• Naturally harvested walnuts that are not dried or properly packaged spoil quickly.

• Walnuts contain many fatty acids that oxidize when exposed directly to air, causing an unpleasant rancid smell.

• Unsuitable temperature and light conditions can also damage the walnuts.

Therefore, to preserve the full nutritional value of walnuts, it is essential to store them correctly.

Effective Methods to Store Walnuts

Based on the above information, you understand the importance of proper walnut storage to maintain quality and nutritional content. So, how should walnuts be stored correctly?

For Walnuts with Shells

Walnuts with shells are much easier to store. The walnut kernel is wrapped in a thin membrane rich in antioxidants, and outside of that is a hard, tight shell that protects the nut inside. To store shelled walnuts, you should place them in airtight plastic bags and remove as much air as possible.

After each use, make sure to seal the bag tightly. Removing air inside the bag prevents moisture buildup that can affect the quality and flavor. Store the walnuts in a cool place away from direct sunlight and humidity. If you buy walnuts in large quantities and plan to use them over a long time, refrigeration is recommended to maintain freshness.

For Shelled Walnuts (Without Shells)

If you buy walnuts already shelled, the storage method differs. Without the protective hard shell, shelled walnuts are more prone to moisture absorption and quality degradation. Improper storage will lead to a noticeable decline in flavor.

If you have a large quantity of shelled walnuts for long-term use, divide the daily amount into small portions, seal each in airtight plastic bags with the air removed, or store them in airtight glass jars.

Similarly, store them in a cool place away from direct sunlight, high temperatures, and humidity. Refrigeration is the best way to extend their shelf life and preserve quality. To enjoy a richer flavor, you can roast shelled walnuts before eating.

For Processed Walnuts

Processed walnuts are much easier to store. Simply place them in airtight plastic bags or glass jars and keep them in the refrigerator to consume gradually. Walnut milk or other walnut-based products should also be refrigerated to maintain freshness and taste.

Additional Tips for Choosing and Storing Walnuts

• Choose walnuts with intact shells, without cracks or damage.

• Pick walnuts that are large, uniform in size, firm, and heavy for their size.

• For shelled walnuts, select plump, dense kernels that are free from mold.
