Understanding Freeze Drying

Freeze drying is a process where you remove water from a food material by freezing it. Then, you turn the ice into vapor by putting the item under pressure. Hence, you can see that this process is a dehydration technique where you sublimate the water in a product.

It means that the water content in your product changes from a solid state to a gaseous state (sublimation). Here, the water does not turn into liquid.

Generally, this method is helpful when you want to preserve any perishable materials. Here, the goal is to extend the shelf life of the material. In this case, you freeze the material and reduce the pressure. Then, you add heat to allow the frozen water in the food (material) to change directly to vapor.

How Does Freeze Drying Work?

Freeze drying consists of three stages: freezing, sublimation, and desorption.

Here is an explanation of the three stages:

1. Freezing

This process involves freezing the food at a very low temperature. Generally, you have to freeze to -30 to -50°F.

2. Sublimation (Primary Drying)

In this stage, you have to pass mild heat over the frozen material while the material is under vacuum. Hence, the ice crystals vaporize into water vapor. After that, you remove the water vapor with the help of a vacuum pump.

3. Desorption

This is the second stage of drying. Here, you have to remove all the remaining moisture from the surface of the food.

Benefits Of Freeze Drying Food

The following are the major advantages of freeze-drying that will benefit you a lot:

Generally, the foods that you freeze-dry retain up to 97% of their nutritional value. For instance, the food retains vitamins, minerals, and antioxidants.
Those foods have a long shelf life. Moreover, you do not need to store it in cold chains.
Once you freeze-dry your food, you will end up removing 98% of its water content. Hence, you will reduce its weight by 90%. Thereby, it will be easy for you to carry that food on camping and backpacking trips.
Freeze-dried food is easy to prepare. This is because you just have to add water to rehydrate them. Moreover, the shape and size of the food remains intact. Also, freeze-drying helps in preventing the growth of pathogenic organisms.
You can preserve a wide range of foods with freeze-drying. This includes meat, fish, fruits, vegetables, eggs, ice cream, and more.
When you freeze-dry food, it does not get brown or caramelize. However, this is quite common when you dry food traditionally.

How To Freeze Dry Food At Home?

Here are the steps you must follow to freeze dry food at home:

Wash your food items that you want to freeze-dry. Also, remove dirt and residues from the food. This way, you can ensure food safety.

Place your food in your freezer, and set the temperature correctly. Then, place the food in your freezer for two weeks. Actually, you need this time to remove the moisture in the food.
After the completion of two weeks, remove the trays from the freezer. After that, quickly place the food items in airtight bags. Make sure to take out one tray at a time to ensure that the food does not rehydrate.
Make sure to place the food bags in the freezer, and also in a cool, dark spot.
Check the food after a couple of days. This way, you ensure whether all the food is dried-up or not.

Tips For Successful Freeze Drying

4. Store The Food

Once you freeze-dry your food, store it in an airtight container. Also, you can store it in a bag which you can vacuum-seal it.
