The Science Behind Freeze Drying: Transforming the Texture and Flavor of Candy


You've probably heard of freeze-dried fruits and maybe even freeze-dried ice cream, but have you ever wondered about freeze-dried candy? At Crunchy Candy Corner, we specialize in creating freeze-dried versions of your favorite candies, like Skittles, transforming them into a crunchy delight. But what exactly is the freeze-drying process, and how does it change the texture and flavor of candy? Let's dive into the fascinating science behind freeze drying.

What is Freeze Drying?

Freeze drying, also known as lyophilization, is a method of preserving food by removing its moisture content. Unlike traditional drying methods, which involve heat, freeze drying uses extremely low temperatures and a vacuum to achieve its results.

The Three Main Steps of the Freeze Drying Process

1. Freezing

The first step involves freezing the candy at temperatures as low as -40°F to -80°F. This ensures that the water content in the candy turns into ice.

2. Primary Drying (Sublimation)

Once frozen, the candy is placed in a vacuum chamber. The pressure is lowered, allowing the ice to sublimate, or transition directly from a solid to a gas, bypassing the liquid phase.

3. Secondary Drying (Desorption)

In this final step, any remaining moisture is removed from the candy at slightly higher temperatures, ensuring that it's completely dry.

How Does Freeze Drying Affect Texture?

The freeze-drying process transforms the texture of the candy from chewy to crunchy. Because the water is removed without melting or altering the structure, the candy retains its original shape but gains a new, satisfying crunch.

How Does Freeze Drying Affect Flavor?

You might be surprised to learn that freeze drying can actually intensify flavors. Since the water content is removed, what remains is a concentrated form of the candy, making each bite a burst of flavor.

Why Choose Freeze-Dried Candy?

  • Longer Shelf Life: The removal of moisture extends the shelf life of the candy.
  • Unique Experience: The change in texture and flavor offers a new and exciting way to enjoy classic candies.
  • No Preservatives: Freeze drying is a natural process that doesn't require the use of preservatives.


The freeze-drying process is a scientific marvel that not only preserves food but also transforms its texture and flavor. At Crunchy Candy Corner, we've harnessed this technology to create a whole new candy experience for you. So the next time you enjoy a crunchy Skittle, you'll know the fascinating science that made it possible.
