Nuts in shell should be stored dry, cool and airy, preferably in nets. This way they can be stored for several months. Processed nuts (shelled, ground, chopped, sliced, roasted, seasoned) should be stored protected from oxygen and sunlight at ideally 15 degrees. Closed, opaque packaging is particularly suitable for this. The contents of opened packages should be used up quickly. This is because nuts can become rancid due to their high fat content. In addition, nuts mould quickly, forming substances that are harmful to health. Discoloured and mouldy nuts must therefore no longer be eaten.
