How Does Freeze Drying Work?
Freeze drying, or lyophilization, involves removing moisture from food while maintaining its structure and nutrients. The process consists of three main stages: freezing, primary drying, and secondary drying.
- Freezing: The food is rapidly frozen to preserve its cellular structure.
- Primary Drying: Under vacuum, ice sublimates directly into vapor, removing moisture without liquid water.
- Secondary Drying: Remaining moisture is removed, ensuring the food is shelf-stable.
This method preserves 90-95% of the food’s original nutrients, making it a superior option compared to traditional canning or dehydrating.

- Long Shelf Life: Freeze-dried foods can last for 25 years or more if stored properly.
