The Secret to Storing Nuts and Seeds

Nuts and seeds are nutritious, versatile pantry staples packed with healthy fats, protein, fibre, vitamins and minerals. Whether you enjoy almonds as a snack, sprinkle chia seeds over your breakfast, add sunflower seeds to salads or use walnuts in baking, proper storage is essential to maintaining their freshness, flavour and nutritional quality.

However, nuts and seeds can spoil faster than you might expect. Their natural oils are sensitive to heat, light and oxygen, which can cause them to turn rancid and develop an unpleasant taste or smell.

1. Choose the Right Storage Conditions

• Pantry: Store nuts and seeds in airtight containers in a cool, dry, dark place, away from direct sunlight and heat.

• Refrigerator: Ideal for oil-rich nuts such as walnuts and pecans, as well as seeds and products you want to keep fresh for longer.

• Freezer: Best for bulk purchases and long-term storage. Use airtight, freezer-safe containers or bags to prevent moisture and odour absorption.

In warmer climates, refrigeration is often the best option for extending freshness.

2. Use Airtight Containers

Store nuts and seeds in clean, dry, airtight containers or resealable bags. Seal them tightly after each use to limit exposure to air and moisture. Label containers with the opening date, and keep products away from strong-smelling foods.

3. How Long Do Nuts and Seeds Last?

Storage times vary depending on the product, packaging and conditions. Most nuts can last up to 12 months in the fridge.

4. Special Tips for Seeds

• Flaxseeds: Whole seeds keep better than ground flaxseed. Refrigerate ground flaxseed after opening.

• Chia seeds: Keep sealed and dry; refrigeration is useful in warm conditions.

• Pumpkin and sunflower seeds: Refrigerate or freeze for longer storage.

• Hemp seeds: Refrigerate after opening because of their delicate oils.

These four simple habits help reduce food waste and keep your favourite nuts and seeds fresh for longer.

Happy Spring everyone! Ruth
