Good packaging and storage techniques are crucial. Packaging protects your dried food from oxygen, moisture (gain or loss), light, microorganisms, and pests. After you have checked foods and found them to be thoroughly dry and cool, pack them immediately for storage.
Some pieces of fruit will be more moist than others after drying so it is a good idea to condition fruits before long-term storage. Conditioning distributes moisture evenly in the fruit. It reduces the chance of spoilage, particularly from mold.
To condition, loosely pack cooled, dried fruit in plastic or glass containers to about two-thirds full. Cover the containers tightly. Shake them daily for about 2 to 4 days. The excess moisture in some pieces will be absorbed by the drier pieces. If you notice water forming on the container lid, place the fruit back in the dehydrator. Because vegetables dry to a nearly waterless state, conditioning vegetables is not necessary.
