How is Freeze Dried Food Made? & What is Freeze-Dried Food
To understand what freeze-dried food is, you will first need to know how it is made. Freeze-dried food is made using a process that involves flash freezing and vacuum drying. Flash freezing is the process of rapidly lowering the temperature of food to well below the freezing point, which helps to lock in the food’s flavor, texture, and nutrients.
Once the food is flash frozen, it is then placed in a vacuum chamber. The vacuum chamber lowers the pressure and raises the temperature, causing the ice in the food to turn directly into water vapor through a process called sublimation. By removing the water in the form of water vapor, the food becomes dehydrated and dry.
Since the food is freeze-dried without ever becoming liquid, it retains its original shape, color, and flavor once it is rehydrated. This makes freeze-dried food a popular option for preserving a wide variety of foods, including fruits, vegetables, meats, and even entire meals. And since freeze drying removes all the water from the food, it can be stored for a long time without spoiling.
