What are freeze dried foods?

Freeze dried foods are just like the name suggests. They are foods that have been frozen and then dried out in a process called "freeze drying." This is done to preserve them for long periods of time without refrigeration or freezing and reduce weight and volume so they can be transported easily.

How are freeze dried foods made?

Freeze dried foods are made through a precise process different from any other type of food preservation. Freeze-drying is the process of freezing food and lowering its temperature to a particular point, known as the "triple point."

At low temperatures, the moisture in food can change from a solid state to gas without changing into liquid. This is a delicate science perpetuated by precise cooling, heating, and control of atmospheric pressure. Packaging for sale usually follows a two-step drying process.

The quality of freeze dried foods

Gone are the old days of bland and tasteless freeze dried foods. Nowadays, you can get many freeze dried foods that actually have a good flavor and taste. However, food quality is determined largely by how it's been made and the ingredients used to make them.

If someone wants variety from their prepper meals, freeze dried foods should be on their list when considering what type of emergency preparedness food to keep stocked up on.

Shelf life of foods that have been freeze dried

The shelf life of freeze dried foods depends on the food itself, how it was packaged and its quality.

The shelf life of some items can be up to 25 years, although the labels may say only 5-7. This is a conservative estimate, and there are even some companies out there now that claim their products will last up to 30 years.

Freeze-dried fruits will last slightly longer than vegetables or starches because they contain more sugar, which helps them stay preserved.

The best way to store these types of goods is in sealed packages with oxygen absorbers that have been specifically made for this type of item.

Freeze dried foods manufacturers often pack their goods in sealed Mylar packages, and many of them contain oxygen absorbers that have been specifically made for this type of item. An alternative that is also used is #10 cans (10-pound cans), which are common for storing foods.

How to store freeze dried foods

Freeze dried foods should be stored away from direct sunlight or any other type of light that will cause the food to deteriorate. It should also be kept at, and preferably below, room temperature.

Freeze dried foods that are subjected to higher temperatures, or extreme temperature fluctuations, can degrade faster and lose some of the qualities that make them so great to use.

This includes color, flavor and texture changes.

Freeze dried foods are specifically made with as low of moisture left in them as possible, so you want to keep them tightly sealed and away from any moisture.

Once you open a package or can of freeze dried food, it will last up to one week if you haven't added water. Once prepared with water, it is only good for a few days - treat it like any other leftover food and refrigerate properly.
