Originally created for soldiers and astronauts, freeze dried food is now popular survivalist items due to their long shelf life and ability to retain nutrients and flavor. Although canned and dehydrated food preserves just as well, these kinds of survival foods are vulnerable to loss of flavor and nutritional content that is so important to continued good health following a widespread disaster.
Also called "lyophilization", freeze-drying is similar to putting food into suspended animation by rapidly freezing it and then immediately putting it into a vacuum. When the food finishes the process, it is more compact and lighter, making it perfect to carry in a backpack or bug-out bag. This is because freeze dried food loses around 98 percent of the moisture originally contained in the food.
To eat foods that are freeze dried, you just add boiling water, wait a
couple minutes and then eat. When boiling water is inaccessible, you can
rehydrate freeze dried foods with cold water; however, it will take
food much longer to rehydrate and become edible. Also, some food that is
freeze dried can be eaten without rehydration as a crispy or crunchy
snack, such as the freeze dried ice cream.
When tightly sealed to prevent moisture from seeping into a freeze dried meal, packages containing this type of preserved food will remain unspoiled and edible for ten years or more. Because most of the water has been removed from these foods, enzymes and microorganisms responsible for rotting food cannot live in such dry environments.
