How freeze-drying works?
Freeze drying works by first freezing a substance, then lowering the pressure around it to a vacuum, which allows the frozen water to directly transition from a solid (ice) to a gas (water vapor) through a process called sublimation, effectively removing the water content without going through a liquid phase, thus preserving the material's structure and properties; this is often used to preserve food, pharmaceuticals, and biological samples by significantly extending their shelf life.

Retains nutrients: Freeze-dried food retains up to 97% of its nutrients, including vitamins, minerals, and antioxidants. Long shelf life: Freeze-drying removes the potential for bacterial growth, so freeze-dried food can last for years. Maintains flavor and texture: Freeze-drying preserves the original shape, flavor, and texture of food. Sustainable: Freeze-drying reduces food waste and transportation and storage costs.
