Adding Freeze Dried Foods to your emergency food supply is a smart choice for several reasons… we point out those reasons below, along with some facts about the freeze drying process.
*Keep in mind– if there is a sudden food shortage emergency, many people will be trying to purchase all types of emergency foods at the same time, then you will NOT be able to find them due to shortages.
*After the March 2011 earthquake in Japan, emergency foods were on back-order for up to 6 months (in the USA), from suppliers.
It is wise and in your best interest, as with ALL emergency preparedness steps, to prepare now…before it is too late.
Excellent Choice For Emergency Preparedness
- Freeze Dried Food actually tastes good.
- Easily stored in small spaces.
- Convenient to pack in emergency kits.
- They can be stored for up to 25 years.
- Foods are easy to transport and are lightweight.
- They can be purchased quickly and conveniently from several quality retailers. (We recommend a few on the right side column)
What is Freeze Drying?
Freeze-drying is a cold-dehydration process typically used to preserve a perishable material or make the material more convenient for transport.
This method works by freezing the material and then reducing the surrounding pressure and adding just enough heat to allow the frozen water in the material to sublime directly from the solid phase to gas.
The phenomenon used in freeze drying, is what allows wet cloth to be hung outdoors in freezing weather and retrieved later in a dry state.

Facts about Freeze Dried Foods: Pros and Cons
- When a freeze-dried substance is sealed to prevent the re-absorption of moisture, the food may then be stored at room temperature without refrigeration, and be protected against spoilage for many years.
- The greatly reduced water content inhibits the action of microorganisms and enzymes that would normally spoil or degrade the substance. This same process makes the foods very lightweight.
- Freeze-drying causes less damage to food than other dehydration methods using higher temperatures, leaving more nutrient value in the food.
- This process does not usually cause shrinkage or toughening of the material being dried. In addition, flavors and smells generally remain unchanged, making freeze-dried foods very popular as a food storage option.
- Freeze-dried products can be re-hydrated quite quickly and easily because the process leaves microscopic pores.
- Because of these many survival food qualities, freeze dried foods are a popular choice for emergency disasters, campers, hikers, and even military personnel.
- Unlike food dehydrating, freeze drying cannot be performed without commercial equipment, therefore the freeze drying process is not available to the general public as a way of preserving their own foods.
