Freeze drying process：
Fresh or cooked foods are placed in the dryer where they are frozen to -40 degrees Fahrenheit or colder.
Once the food is frozen, the freeze dryer creates a powerful vacuum around the food. Then, as the food is slightly warmed, the ice transitions into vapor and evaporates.
The freeze-dried food is then sealed in moisture and oxygen-proof packaging (Mylar bags, mason jars, or cans) along with an oxygen absorber to ensure freshness until opened.
When water is added to the food it regains its original fresh flavor, aroma, and appearance!
