Making Freeze-Dried Candy: Air Fryer Magic

Freeze-dried candy is a unique treat that transforms well-known candies into something with a recognisable taste but an entirely new texture and appearance. The process of freeze-drying involves removing 98-99% of the water content from the candy, which bacteria need to decompose the food. This gives the candy a crunchy texture. Freeze-drying candy can be done at home by using a freezer or dry ice. However, it is not possible to make freeze-dried candy in an air fryer as air fryers use superheated air for cooking food and are incapable of freezing anything.

Freeze-dried candy is a unique treat that transforms well-known candies into something with a recognisable taste but an entirely new texture and appearance. The process of freeze-drying involves removing 98-99% of the water content in the candy, which bacteria need to decompose the food. This means that freeze-dried candy has an incredibly long shelf life.

Freeze-drying requires the candy to be cooled to around 50 degrees Fahrenheit below zero. A vacuum pump then removes almost all the air from the chamber, leaving the food under nearly zero pressure. The food is then slightly warmed, and the ice crystals evaporate before they are warm enough to melt. Finally, the food is warmed to over 100 degrees Fahrenheit, still under zero pressure.

Air fryers use superheated air to cook food and are incapable of freezing anything. Therefore, the properties of an air fryer make it impossible to use to make freeze-dried foods.

While it is possible to freeze-dry candy in a freezer, this is a much less efficient process than using a freeze-dryer. The freezer must be able to maintain temperatures of around 30 degrees Fahrenheit colder than a standard home freezer for several weeks, and the process will still not remove as much water content as a freeze-dryer.

Freeze-dried candy can be made in a freezer

Freeze-dried candy is a fun experiment and a novel treat. The process of freeze-drying involves removing 98-99% of the water content in food, so bacteria cannot decompose it. This results in a dry, porous texture, and a crunchier mouthfeel. The taste is also more accentuated due to the lack of water.

While freeze dryers are the best way to achieve this, they are expensive, so here is a method using a standard freezer:

How to Make Freeze-Dried Candy in a Freezer:

Firstly, line a baking tray with parchment paper to avoid sticking. Then, place your chosen candy on the tray in a single layer, ensuring each piece has space around it to dry evenly. You can use any candy you like, but fruit-based candies like Skittles, gummy bears, and worms, as well as marshmallows and hard candies like Jolly Ranchers, work particularly well.

Place the tray in the freezer and leave the candy to freeze for 2-3 weeks. Try not to open the freezer door during this time, and avoid moving the tray or candy. A deep freezer in a garage is ideal as it is less likely to be opened.

After 2-3 weeks, remove the candy from the freezer and place it in freezer bags. Store the bags in a cool, dry place and wait a few hours for the candy to reach room temperature before eating.

Tips:

• Breaking the candy into smaller pieces will help it dry more evenly and improve the final texture and appearance.
• The drying time will vary depending on the candy's size and type, so test a piece before packaging. It should be void of all moisture and feel light and airy. If it still feels cold or damp, return it to the freezer for a few more hours.
• To store your freeze-dried candy, use airtight containers like Mason jars or Mylar bags, and add oxygen absorbers to keep the candy crispy.

Other Methods:

While a freezer is a good alternative to a freeze dryer, it is worth noting that other suggested methods, such as using a dehydrator or an air fryer, will not work. Dehydrators use heat and evaporation to remove water, resulting in a chewier product. Air fryers cook food with superheated air, so they cannot be used for freezing.

Dry ice can also be used to freeze-dry candy, but this must be done with caution, following safety instructions and using the proper equipment, including thermal gloves.

Freeze-dried candy can be made using dry ice

Freeze-dried candy is a fun project that can be a novel gift and even offer a side income. It brings a new spin to treats because it changes everything about their taste and feel. The process involves freezing candy, then using a vacuum to turn the ice into vapour. By eliminating all the water and keeping just the sugar, you end up with a crispier texture, more flavour, and a longer shelf life.

While it is not recommended to attempt freeze-drying without a machine, it is technically possible to use dry ice to freeze candy. However, this method must be done with caution. Always follow the safety instructions provided by official sources, such as the NYDOH website, and ensure you have the proper thermal gloves and other equipment before you start.

To freeze-dry candy with dry ice, place your chosen candy in freezer bags and, without fully sealing them, place the bags into a cooler. Cover the candy with dry ice for at least 24 hours, ensuring there is no humidity. Do not seal the cooler, as this could cause an explosion. After this time has passed, open the bags and carefully transfer the candy to new, clean bags. Finally, store the candy in a cool, dry place and enjoy.

It is important to note that freeze-drying candy with dry ice may not yield consistent results that are safe to store long-term. If you are interested in consistently making freeze-dried candy, investing in a freeze-drying machine is recommended.

Dehydrators cannot make freeze-dried candy

Freeze-drying requires temperatures well below freezing so that every molecule of water can crystalize into ice. In the second phase, water molecules sublime into water vapour in a vacuum or near-vacuum environment. In the third phase, desorption removes any remaining water and ice through a chemical process.

Dehydrators, in contrast, use heat to evaporate moisture content from food. They are designed to circulate a lot of air with some heat. Dehydrators typically operate at temperatures between 90°F and 145°F, which is significantly higher than the temperatures required for freeze-drying.

While both dehydrators and air fryers use heat to cook, they differ in the way they operate. Air fryers use hot air at high temperatures to cook food, while dehydrators use dry heat at lower temperatures. Air fryers are great for cooking vegetables and meats, as they don't require any oil. Dehydrators are perfect for drying out fruits and vegetables but cannot be used for baking, broiling, roasting, or reheating.

Freeze-dried candy is more nutritious than dehydrated candy

It is not possible to make freeze-dried candy in an air fryer. Air fryers use superheated air for cooking food and are incapable of freezing anything. However, freeze-dried candy has gained popularity in recent years, and for good reason.

The flavour of the candy is also preserved and even intensified in freeze-dried candy, as there is no water to dilute the taste. The nutrients are also retained, and the candy can last up to 25 years in the right conditions. Freeze-dried candy made from fruit retains most of the vitamins and minerals found in fresh fruit, making it a nutritious snack option.

In addition to the nutritional benefits, freeze-dried candy is also lightweight, easy to store, and has a long shelf life. The lack of moisture means there is less weight to carry, and bacteria cannot grow, giving it an extremely long shelf life. This makes it a perfect snack for space travel, events, and adventures.

While freeze-dried candy offers several advantages over dehydrated candy in terms of nutrition and taste, it is important to remember that, like all candy, it should be enjoyed as part of a well-balanced diet due to its high sugar content.
