Freeze-dried meals are food products that have had most of their moisture removed through a process called freeze-drying. This method involves freezing the food and then slowly heating it in a vacuum, which causes the ice to turn directly into vapor. The result is lightweight, shelf-stable meals that can last for years without refrigeration. These meals are popular for outdoor activities like camping and hiking, as well as for emergency preparedness. To eat them, you simply add hot water and wait a few minutes for the food to rehydrate. This makes freeze-dried meals a convenient option for quick and easy nutrition.
