Is it OK to eat freeze dried food?
Other nutrients, such as vitamins C and E and folic acid, are somewhat depleted through the freeze-drying process. Once rehydrated, freeze-dried food is similar in nutritional value to fresh food according to Diane Barrett, a food science and technology prof at UC-Davis.
Does Astronaut Ice Cream expire?
Answer: Nope! Astronaut Ice Cream is freeze dried, which means that they're completely dehydrated (and feel a bit like a cracker) and can be stored at room temperature indefinitely. Answer: Astronaut Ice Cream has a shelf life of three (3) years.
Is freeze dried ice cream cold?
Freeze-dried ice cream is ice cream that has had most of the water removed from it by a freeze-drying process, sealed in a pouch, and requires no refrigeration. Compared to regular ice cream, it can be kept at room temperature without melting and is more brittle and rigid but still soft when bitten into.
Can freeze dried food go bad?
If the pouch or can is out of date and the food inside is still dry, it will be safe to eat, though the flavor may be a bit bland if you're a few years past the "best by" date. The lifetimes of all of these freeze dried foods, no matter how it's packaged, can be extended by storage in cool conditions.

Another common tip is if you are adding freeze-dried meats to another entree for an added punch of protein, do so in cold water. Meats rehydrate faster in hot water, so to keep the texture in tact, rehydrate in cold water and then add to whatever you're cooking.
Is freeze dried food bad for you?
Other nutrients, such as vitamins C and E and folic acid, are somewhat depleted through the freeze-drying process. Once rehydrated, freeze-dried food is similar in nutritional value to fresh food according to Diane Barrett, a food science and technology prof at UC-Davis.

Can you eat freeze dried food without water?

How does freeze drying work?
Freeze drying is a water removal process typically used to preserve perishable materials, to extend shelf life or make the material more convenient for transport. Freeze drying works by freezing the material, then reducing the pressure and adding heat to allow the frozen water in the material to sublimate.
