What is Freeze Drying?
Freeze-drying is a process that removes moisture from a substance while preserving its structure and texture. The process involves freezing the substance, then placing it in a vacuum chamber, where the ice crystals sublimate or transform from a solid to a gas without going through a liquid phase. This results in a dried substance with a porous structure that retains its original texture and flavour.
Materials Needed
Before we dive into the freeze-drying process, let’s first look at the materials you’ll need to freeze -dry candy:
- Candy
- Freeze dryer
- Vacuum pump
- Vacuum chamber
- Oxygen absorber packets
- Sealable bags
Step-by-Step Guide to How to Freeze Dry Candy
Now that you have all the materials needed let’s go through the freeze-drying process step-by-step:
Step 1: Preparing the Candy
Start by selecting the candy you want to freeze dry. You can use any candy, including gummies, hard candies, chocolate, and more. Next, place the candy in the freezer and freeze it overnight. This step helps preserve the candy’s shape and structure during the freeze-drying process.
Step 2: Setting Up the Freeze Dryer
Once the candy is frozen, it’s time to set up the freeze dryer. Start by assembling the freeze dryer and connecting the vacuum pump to the chamber. Place the frozen candy in the freeze dryer tray and arrange them in a single layer.
Step 3: Starting the Freeze Drying Process
Close the vacuum chamber and turn on the vacuum pump. This will remove the air from the chamber, creating a vacuum. The vacuum helps remove the candy’s moisture during the freeze-drying process.
Once the vacuum is created, turn on the freeze dryer and set the temperature to -40 degrees Celsius. The freeze dryer will start to remove the moisture from the candy.
Step 4: Monitoring the Process
The freeze-drying process can take 24 to 48 hours, depending on the type and amount of candy you’re freeze-drying. Monitoring the process regularly is essential to ensure that the candy is drying evenly. You can do this by checking the freeze dryer periodically and rotating the trays if necessary.
Step 5: Sealing the Freeze-Dried Candy
Once the freeze-drying process is complete, remove the candy from the freeze dryer and place them in sealable bags. Add an oxygen absorber packet to each bag to remove any remaining moisture. Seal the bags and store them in a cool, dry place.
Benefits of Freeze-Drying Candy
There are several benefits to freeze-drying candy, including:
Extended Shelf Life: Freeze-drying removes moisture from the candy, extending its shelf life by up to 25 years. This makes freeze-dried candy an excellent option for long-term food storage.
Preserves Texture and Flavor: Freeze-drying preserves the texture and flavour of the candy, making it taste just as good as it did before the process.
Lightweight and Portable: Freeze-dried candy is lightweight and easy to transport, making it an excellent snack option for camping, road trips, or any time you go.

Tips for Freeze Drying Candy
Freeze-drying candy is a great way to extend its shelf life while preserving its texture, flavour, and appearance. However, this process can be tricky, and certain factors can affect the quality of the final product. Here are some tips to help you freeze dry candy successfully:
Choose the Right Candy: As mentioned earlier, not all candies are suitable for freeze-drying. Stick to hard candies, gummies, and marshmallows, as they freeze dry well and retain their shape and texture.
Freeze the Candy First: Freezing the Candy before placing it in the freeze dryer helps remove any excess moisture and prepares it for the freeze-drying process.
Use a Good Quality Freeze Dryer: Invest in a good quality freeze dryer that can handle the type and quantity of Candy you want to freeze dry. Cheaper models may work less efficiently or may produce inconsistent results.
Follow the Manufacturer’s Instructions: Every freeze dryer is different, and it’s crucial to follow the manufacturer’s instructions when operating the machine. Make sure you understand the settings and controls before you start the process.
Arrange the Candy Properly: Arrange the frozen candies in a single layer on the trays of the freeze dryer. This ensures even drying and prevents them from sticking together.
Don’t Overload the Freeze Dryer: Overloading the freeze dryer can affect the quality of the final product. Follow the manufacturer’s guidelines regarding how much Candy you can freeze dry in one batch.
Store the Freeze-Dried Candy Correctly: Once you’ve freeze-dried the Candy, store it in an airtight container and add a desiccant packet to absorb any moisture. Keep the container in a cool, dry place away from direct sunlight.
Conclusion
Freeze-drying candy is an excellent way to preserve its texture and flavour while extending its shelf life. With the right materials and a step-by-step process, you can easily freeze dry any candy at home.
