What is Freeze-Drying?

Freeze-drying, also known as lyophilization, removes water from a product through sublimation. In this process, water transforms directly from ice to vapor, bypassing the liquid stage. This technique effectively preserves the nutritional value, taste, and appearance of foods while significantly extending their shelf life.

How Does Freeze-Drying Work?

The freeze-drying process consists of three main steps:

Freezing: First, the product is frozen under atmospheric pressure.

Primary Drying: Next, frozen free water is removed through sublimation.

Secondary Drying: Finally, the remaining bound water is removed to achieve the desired humidity level.

Benefits of Freeze-Dried Foods

Freeze-dried foods retain their original flavor, color, and structure, making them highly nutritious. This method also preserves antioxidants and beneficial plant compounds like phytochemicals. Moreover, freeze-drying effectively extends shelf life by preventing the growth of bacteria, yeasts, and molds.
