How is freeze-dried candy made?

Freeze-dried candy is made through a process called freeze-drying, also known as lyophilization. This method involves freezing the candy and then removing the water content through sublimation. Here is a short summary of how freeze-dried candy is made:

1. Freezing: The candy is placed in a freezer and cooled to a very low temperature, typically below -40 degrees Celsius (-40 degrees Fahrenheit). This freezing step helps preserve the shape and structure of the candy.

2. Vacuum Chamber: The frozen candy is then transferred to a vacuum chamber. The chamber creates a low-pressure environment, which allows for sublimation to occur. Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. This process can take up to 12 Hours!!!

4. Packaging: Once the freeze-drying process is complete, the candy is typically packaged in airtight containers to maintain its crisp texture and prolong its shelf life. This packaging helps prevent moisture from re-entering the candy, which could cause it to rehydrate and lose its freeze-dried state.

The freeze-drying process helps retain the original flavor, color, and shape of the candy while removing the water content. This results in a lightweight and crispy texture that quickly rehydrates when consumed. Freeze-dried candy is popular due to its long shelf life, portability, and intense flavor experience.
