Prof. William Dalton, Ph.D.Correct storage keeps the fresh flavor and nutritional value of cashew nuts for months. These nuts have a high oil content, and if not properly stored, they will become rancid. I have tried several methods of storage in my work as a nutritionist, and I have found that the techniques described here give the longest storage with the least spoilage.
Pantry Storage
- Use airtight opaque containers blocking light exposure
- Maintain consistent temperature below 77°F (25°C)
- Add silica gel packs to absorb ambient moisture
- Maximum shelf life: 1 month
Refrigeration Method
- Vacuum-seal portions in moisture-proof bags
- Set refrigerator temperature between 34-40°F (1-4°C)
- Place near back away from temperature fluctuations
- Maximum shelf life: 6 months
Long-Term Freezing
- Use double-bagged portions in freezer-safe materials
- Maintain freezer at 0°F (-18°C) or lower
- Pre-portion before freezing to avoid thaw-refreeze cycles
- Maximum shelf life: 12 months
The control of moisture is the most important factor in preventing spoilage. When cashews absorb moisture, they become soft, and mold may also form. I always include food-grade silica gel packs in the containers I use. Also, for bulk storage, oxygen absorbers help with rancidity.
Existing Convenience in proportions during storage. For refrigeration or freezing, quantity 28g meals in small bags. In this, it is not exposed to air. This helps control portion size during use, particularly in instances where dietary benefits are a concern.
To retain their qualities, frozen cashews should be defrosted slowly. Whenever possible, portions of nuts should be taken from the freezer and placed in the refrigerator twenty-four hours before use. These should not be refrozen after thawing, as the temperature alterations will cause condensation, affecting the quality of the cashews. By following the method described here, the best possible result will be achieved in terms of texture and flavor.
Use the following immediately after purchase. Transfer shop-purchased nuts from their bags to the proper containers and check them for rancidity once a month. This can be detected in the paint-like odor in the air or the bitter taste in the nuts. Proper storage will enable you to maximize the nutritional benefits from every serving.
