What are Freeze-Dried Candy?
You may know how to make freeze-dried candy; it is just ordinary candy that has undergone sublimation, when moisture is removed but there is no heat. This maintains the candy’s structure while providing a crispy texture and a concentrated flavor.
First developed to preserve foods for astronauts and hikers, freeze-drying has exploded in popularity as a technique for transforming beloved confections into one-of-a-kind crunchy snacks.
How Freeze-Drying Works
There are three main stages involved in the freeze-drying process:
Freezing — The candy is cooled to about -40°F (-40°C), typically below that.
Primary Drying (Sublimation): Because of a vacuum, ice in the candy is sublimated into vapor without melting.
Secondary Drying: Any residual moisture is removed, making the candy completely dry and shelf-stable.
The end product is a candy that doesn’t melt but is airy and crunchy in texture.
Advantages of Using Freeze-Dried Candy
Improved Flavor: Flavours are condensed without the moisture.
Distinctive Crunch: Freeze-drying imparts candy a light, crisp bite.
Shelf Life: When kept on the shelf, freeze-dried candy can last for months or even years.
Portable and lightweight: Best for travelling and outdoor uses
Fun and Novelty Appeal: The way freeze-dried candy “explodes” in your mouth when you eat it is appealing to many.
The Best Candies for Freeze-Drying
Freeze-drying is not a great process for all candies. Some of the top choices include:
Marshmallows — They inflate and crisp.
Skittles — They puff up and have an aerated crunch.
Gummy Bears & Worms – Get light and crunchy rather than chewy.
Taffy – Becomes a fragile, crisp texture.
Chocolate Enrobed Candy — Some Can Be Done, Not All
Fatty candy tends to not freeze-dry well and should be avoided.
Equipment and Supplies Necessary
Here are the ingredients to make freeze-dried candy:
A Freeze-Dryer – a specialized machine (for example, Harvest Right freeze-dryer).
Vacuum Pump – Vacuum air for sublimation.
Freezer (Optional)– To pre-freeze the candy.
Baking Sheets or Trays – For laying out candy to dry.
Airtight Containers or Mylar Bags – To store candy you made in the end.
A Step by Step Guide on How to Make Freeze-Dried Candy
Step 1: Prepare the Candy
Pick your candy and, if large pieces, cut them into smaller ones for even drying.
Disperse them evenly on the freeze-dryer trays.
Step 2: Allow to Pre-Freeze (Optional, but Recommended)
Pre-freezing candy for a couple of hours can help dry it more quickly.
Step 3: Load the Freeze-Dryer
Insert trays into the freeze-dryer, then turn the machine on.
Initiate the Process: Starting the Freeze-Drying
The machine will undergo freezing, sublimation, and drying steps.
Depending on the type of candy, this can take anywhere from 12–24 hours.
Step 5: Check the Candy
When done, candy should be clear, air, and crispy.
If it still feels tacky, it needs to dry longer.
Step 6: Store Properly
Store in oxygen absorbers, Mylar bags on airtight containers.
