The candy industry has been swept up by freeze dried candies because of their exceptional blend of crisp texture and strong flavor. Making your own freeze dried candy may be a satisfying and enjoyable hobby, whether your goal is to extend the shelf life of your favorite candies or just try out different textures. Everything you need to know about freeze drying candies will be covered in this comprehensive guide, including the science behind it, how-to guides, and success advice.
Understanding Freeze Drying
Freeze drying, or lyophilization, is a preservation process that removes moisture from food. This method involves three main steps:
- Freezing: The candy is first frozen at extremely low temperatures, usually between -40°F and -50°F (-40°C to -45°C).
- Primary Drying (Sublimation): The frozen candy is placed under a vacuum. The pressure is lowered, causing the ice to sublimate (turn directly from a solid to a gas) without passing through the liquid phase. This step removes about 95% of the water content.
- Secondary Drying (Desorption): The temperature is gradually raised to remove any remaining moisture. This step ensures the candy is completely dry, preventing microbial growth and spoilage.
Why Freeze Dried Candy?
- Intense Flavor: Freeze drying concentrates the flavors, resulting in a more potent taste experience.
- Unique Texture: The process creates a light, airy, and crunchy texture that is unlike any other candy.
- Extended Shelf Life: Without moisture, freeze dried candies can last for years if stored properly.
- No Preservatives Needed: The lack of moisture means there's no need for additional preservatives.
Essential Equipment
- Freeze Dryer: A home freeze dryer is necessary for this process. Brands like Harvest Right offer models that are suitable for home use.
- Candy: Select your favorite candies. Popular options include gummy bears, Skittles, marshmallows, taffy, and more.
- Parchment Paper: To line the trays and prevent sticking.
- Airtight Containers or Vacuum-Sealed Bags: For storing the finished product.
Step-by-Step Guide to Making Freeze Dried Candy
- Choose Your Candies: Select a variety of candies to experiment with. Some candies freeze dry better than others, so it’s good to try different types.
- Cut Large Candies: If you’re using large candies, cut them into smaller pieces to ensure even freeze-drying.
- Line the Trays: Use parchment paper to line the trays. This prevents the candies from sticking.
- Arrange the Candy: Place the candies on the trays in a single layer, ensuring they are not touching. This allows for even air circulation.

Start the freeze-drying Process
- Initial Freezing: Place the trays in the freeze dryer and start the initial freezing process. The machine will lower the temperature to around -40°F (-40°C).
- Primary Drying: Once the candies are frozen solid, the machine will create a vacuum and begin the primary drying phase. The ice will sublimate, removing most of the moisture.
- Secondary Drying: The temperature will gradually increase to remove any residual moisture. This phase ensures the candies are thoroughly dried.
- Check the Candies: Once the process is complete, the candies should be dry, crunchy, and airy. If they still feel slightly moist, you may need to run the drying cycle for a bit longer.
- Store Properly: Transfer the freeze dried candies to airtight containers or vacuum-sealed bags to keep them fresh. Store them in a cool, dry place away from direct sunlight.
Tips for Successful Freeze Drying
- Experiment with Different Candies: Not all candies freeze dry the same way. Start with a small batch and try different types to see which ones you like best.
- Monitor the Process: Keep an eye on the freeze dryer during the process. Some candies might take longer to dry completely.
- Proper Storage: Ensure that the freeze dried candies are stored in airtight containers to prevent moisture from getting back in.
- Use Fresh Candies: For the best results, use fresh candies. Old or stale candies may not freeze dry as well.
Creative Uses for Freeze-Dried Candy
- Snacking: Enjoy freeze-dried candies as a crunchy, flavorful snack.
- Baking: Add freeze-dried candies to cookies, cakes, and other baked goods for an extra crunch and burst of flavor.
- Toppings: Use crushed freeze-dried candies as a topping for ice cream, yogurt, or smoothie bowls.
- Gift Giving: Package freeze-dried candies in decorative jars or bags for unique and delicious gifts.
