Freeze Drying Cheese

Welcome to the world of freeze-dried cheese! In this comprehensive guide, we'll delve deeper into the fascinating process of freeze-drying cheese, step by step. Even if you're a complete newbie to this topic, fear not; we'll break it down into easy-to-understand chunks.

What is Freeze Drying?

Before we dive into freeze-drying cheese, let's grasp the concept of freeze drying itself:

  • Freeze drying, also known as lyophilization, is a preservation method that removes moisture from food while preserving its flavor, texture, and nutritional value.
  • It involves three primary stages: freezing, primary drying, and secondary drying.


The first step in freeze drying is freezing the food, in this case, cheese, to a very low temperature, typically around -40°F (-40°C). This freezing step solidifies the water content in the cheese, turning it into ice.

Freezing is a crucial step because it prepares the cheese for the next phases of the freeze-drying process. It prevents the cheese from collapsing or losing its structure when moisture is removed.

Primary Drying

After freezing, the cheese is placed in a vacuum chamber. This chamber is where the magic happens. The reduced pressure environment allows the frozen water in the cheese to sublimate, which means it changes directly from a solid to a gas without passing through a liquid phase.

Think of it as the ice in the cheese turning into vapor and being pulled out of the cheese, leaving behind a freeze-dried product.

Secondary Drying

While primary drying removes the majority of the moisture, some residual moisture may still be present in the cheese. To ensure all moisture is removed and the cheese remains shelf-stable, it undergoes a secondary drying process.

In this phase, the temperature and pressure are slightly increased to remove any remaining traces of moisture. This step is critical for extending the cheese's shelf life and preventing spoilage.

Why Freeze Dry Cheese?

Now that we understand the basics of freeze drying, let's explore why freeze-drying cheese is a popular choice:

  • Extended Shelf Life: Freeze-dried cheese can last for years when stored properly. This extended shelf life makes it an excellent option for emergency food supplies, long-term storage, and camping trips.
  • Lightweight and Portable: One of the primary advantages of freeze-dried cheese is its lightweight nature. It's incredibly convenient for backpackers, hikers, and outdoor enthusiasts who want to carry a lightweight source of protein and flavor.
  • Preserved Flavor: Freeze drying preserves the authentic flavor of the cheese. Unlike some preservation methods that can alter taste, freeze-dried cheese maintains its delicious and cheesy flavor.
