What Candies Can Be Freeze-Dried?

What Candies Can Be Freeze-Dried

Candies with low moisture content and are solid can generally be freeze-dried. This process involves removing the water content from the candy by freezing it to a solid state and then subjecting it to a vacuum environment, causing the frozen water to sublimate directly into vapor without passing through the liquid phase. Some examples of candies that can be freeze-dried include gummy bears, marshmallows, fruit slices, chocolate-covered fruits, and hard candies. 

However, candies with high moisture content or fillings such as creams or jellies may not be suitable for freeze-drying as they can become mushy or lose their structure during the process. It is important to note that while freeze-drying can preserve the flavor and texture of candies, it may alter their appearance and make them more brittle.

How To Make Freeze-Dry Candy?

Freeze-drying is a process that removes moisture from food items while preserving their taste, texture, and nutritional value. It involves freezing the food at extremely low temperatures and then subjecting it to a vacuum environment, causing the frozen water within the food to sublimate directly from solid ice to vapor without passing through the liquid phase. This results in a dehydrated product that can be stored for an extended period without refrigeration.

Making freeze-dried candy follows a similar process but with some specific considerations due to the nature of the candy. Here is a step-by-step guide on how to make freeze-dry candy:

Choose the Right Candy

Not all types of candy are suitable for freeze-drying. Hard candies, gummies, fruit snacks, marshmallows, and similar confections work best. Avoid candies with fillings or coatings that may not freeze-dry well.

Prepare the Candy

Start by unwrapping or removing any packaging from the candies. If they are large or have irregular shapes, consider breaking them into smaller pieces for more even drying.

Pre-Freeze the Candy

Place the candies on a baking sheet lined with parchment paper or a silicone mat. Make sure they are spread out and not touching each other. Put the baking sheet in the freezer and allow the candies to pre-freeze for at least 2-3 hours. Pre-freezing helps maintain their shape during the freeze-drying process.

Set Up the Freeze Dryer

If you have access to a home freeze dryer, follow the manufacturer’s instructions for setting it up. Ensure that all necessary components are clean and in good working condition.

Load the Candy into the Freeze Dryer

Once your freeze dryer is ready, carefully transfer the pre-frozen candies onto trays or shelves. Again, ensure they are evenly spaced and not touching to ensure proper drying.

Start the Freeze-Drying Process

Close the freeze-dryer door and initiate the freeze-drying cycle according to the manufacturer’s instructions. The process typically involves gradually lowering the temperature inside the chamber while maintaining a vacuum. This allows the frozen water within the candies to sublimate and escape as vapor.

Monitor the Process

Depending on the size and type of candy, freeze-drying can take 24 to 48 hours or longer. It is essential to monitor the process regularly to ensure the sweets are drying properly without becoming overly dehydrated or burnt.

Test for Dryness

After the recommended drying time has elapsed, remove a piece of candy from the freeze dryer and allow it to come to room temperature. Check its texture and moisture content. The candy should be dry, crispy, and have no visible signs of moisture. If it feels soft or sticky, it needs more drying time.

Store and Package

Once your freeze-dried candy is thoroughly dried, transfer it into airtight containers or resealable bags. Properly sealed, freeze-dried candy can last several months or even years if stored in a cool, dry place away from light and moisture.

How To Freeze-Dry Candy Without A Machine?

Here is how you can freeze dry candies without a machine:

Choose the Right Candy

Not all types of candy are suitable for freeze-drying. Hard candies, gummy candies, and fruit snacks work best because they have a lower moisture content than other types of candy. Avoid candies with fillings or coatings that may not freeze-dry well.

Prepare the Candy

Before starting the freeze-drying process, it is essential to prepare the candy properly. Remove any packaging or wrappers from the individual pieces of candy. If the candy is large or thick, consider breaking it into smaller pieces to facilitate faster drying.

Freeze the Candy

Place the prepared candy on a baking sheet lined with parchment paper or a silicone mat. Make sure to space out the pieces so that they do not touch each other. Put the baking sheet with the candy in the freezer and leave it for several hours or overnight until the candy is completely frozen.

Vacuum Seal Bags

Once the candy is frozen, it must be placed in vacuum-sealed bags to remove moisture effectively. Use high-quality vacuum-sealable bags designed for food storage. Place a small number of frozen candy pieces into each bag, leaving enough space for them to move around freely.

Seal the Bags

Carefully seal the bags using a vacuum sealer according to the manufacturer’s instructions. This process will remove air from the bags and create a vacuum seal that prevents moisture from re-entering during storage.

Store in Freezer

After sealing the bags, place them back in the freezer. It is essential to store the candy in a freezer rather than a refrigerator to maintain the low temperature required for freeze-drying.

Wait for Freeze-Drying

The freeze-drying process will take time, typically several days to a few weeks, depending on the size and moisture content of the candy. During this time, the frozen confection will gradually lose moisture, resulting in a freeze-dried texture.

Test for Dryness

To determine if the candy is fully freeze-dried, remove a piece from the bag and let it thaw at room temperature. If it remains dry and crispy without any signs of moisture, it is ready. It needs more time in the freezer if it becomes sticky or chewy.

Store Properly

Once the candy is freeze-dried, transfer it to airtight containers or resealable bags for long-term storage. Keep the containers in a cool, dry place away from direct sunlight and moisture to maintain their quality.

How Are Candy Freeze-Dried Commercially?

Candy freeze-drying is a commercial process that involves removing moisture from candies to extend their shelf life and enhance their texture. This method is widely used in the food industry to preserve the quality and taste of various types of candies. 

The freeze-drying process involves three main steps: freezing, primary drying, and secondary drying.


The first step in candy freeze-drying is to freeze the candies. This is typically done by placing them in a freezer or using specialized freezing equipment. The sweets are cooled to a temperature below freezing, usually around -40 to -50 degrees Celsius (-40 to -58 degrees Fahrenheit). Freezing the candies helps to solidify their structure and prevent them from becoming deformed during the subsequent drying process.

Primary Drying

Once the candies are frozen, they are transferred to a vacuum chamber where the primary drying takes place. In this step, the pressure inside the room is reduced, creating a vacuum. The frozen candies undergo sublimation, which is the direct transition of water from a solid (ice) to a gas (water vapor) without passing through the liquid phase. The low pressure and controlled temperature cause the ice crystals in the candies to vaporize, effectively removing the moisture content.

During primary drying, it is crucial to carefully control the temperature and pressure conditions inside the vacuum chamber. The temperature is typically kept below freezing but above -30 degrees Celsius (-22 degrees Fahrenheit) to prevent any melting of ice crystals. The pressure gradually decreases over time to facilitate efficient sublimation of water from the candies.

Secondary Drying

After primary drying, there may still be residual moisture in the candies. To remove this remaining moisture, secondary drying is performed. The candies are transferred to another vacuum chamber where the temperature is slightly increased. This increase in temperature helps to drive off any remaining water molecules that may be trapped within the candy structure.

During secondary drying, the pressure is further reduced to enhance the drying process. The duration of secondary drying depends on the type and size of the candies but typically lasts several hours to ensure thorough moisture removal. The goal is to achieve a moisture content low enough to prevent microbial growth and maintain the desired texture and taste of the candies.


In conclusion, freeze-dried candy is a fascinating and innovative process that allows for the preservation of the original flavor, texture, and appearance of various candies. By removing moisture through sublimation, freeze-drying creates a lightweight and crispy treat that can be enjoyed for an extended period. The process involves several steps, including pre-freezing the candy, placing it in a vacuum chamber, and gradually increasing the temperature to facilitate sublimation. While freeze-drying candy may require specialized equipment and knowledge, it offers a unique way to enjoy your favorite sweets with a twist. Why not try it and indulge in the delightful world of freeze-dried candy?
