WHAT IS FREEZE DRIED CANDY?

Freeze dried candy is a type of confectionery that has been dehydrated through a process called freeze drying. The first step is creating a vacuum within the freeze drier and then removing the ice by sublimation. This process removes the moisture from the candy while keeping its structural integrity and most of its nutrients, flavor, and color.

WHAT IS FREEZE DRYING?

Freeze drying is a low-temperature dehydration process that involves freezing the product and lowering pressure, removing the ice by sublimation. Because of the low temperature used in processing, the product retains much of its original nutrients, flavor, and color.

  • HOW FREEZE DRYING WORKS

    1. Freezing: The product is frozen to a temperature below its melting point to form an ice matrix.

    2. Primary Drying: Pressure is lowered and heat is applied to sublimate ice crystals, which are then removed by a vacuum pump.

    3. Secondary Drying: Residual water molecules are removed by raising the temperature and pressure to levels that cause them to evaporate.

  • BENEFITS OF FREEZE DRYING

    Preservation of Nutrients: The freeze drying process occurs at low temperatures, which helps to maintain the structure and integrity of the product and preserves the nutrients and flavor.

    Longer Shelf Life: Freeze dried products have a longer shelf life than fresh or dehydrated products because the process removes most of the water content making it more shelf stable and lighter in weight.

    Retention of Shape and Texture: Freeze drying helps to retain the shape and texture of the product, which is important for products that are intended to be rehydrated.
