2. When food is freeze-dried, every bit of water is removed from it.
Without a water content, and the microorganisms that go along with
it, food is less likely to spoil, even if it remains at room temperature for
many years. Freeze drying also allows the food being preserved to
keep its original texture, flavor and smell, which gives it an
advantage over other food preservation methods.
