Freeze Dried Candy Technology

Candy freeze-drying technology is a technique that uses the principle of lyophilization to remove water from candies, preserving their original shape, color, and taste. This technology is primarily used in the production of freeze-dried candies, such as freeze-dried fruit slices and freeze-dried chocolates.

The process of making freeze-dried candies mainly includes the following steps:

Pretreatment: The raw materials are cleaned, peeled, sliced, etc., and then soaked in syrup or boiled in sugar to allow the candy materials to fully absorb sugar content.

Freezing: The treated candy materials are placed in a low-temperature freezing device to quickly freeze them into a solid state.

Freeze-drying: The frozen candy materials are placed in a freeze-dryer, where, through a low-temperature and vacuum environment, the water within is directly sublimated into a gaseous state, thereby removing the water from the candies.

Packaging: The freeze-dried candies are packaged to maintain their freshness and texture.

China also has certain research and applications in candy freeze-drying technology. For example, institutions like the Institute of Agro-Products Processing Science and Technology at the Chinese Academy of Agricultural Sciences have achieved certain results in the research of freeze-drying technology. Overall, candy freeze-drying technology is a very promising technique that plays an active role in promoting the development of our country's candy industry.
