Yes, you can freeze dry goat milk.
Based on the YouTube video titled "Freeze Drying Goat Milk | Three Little Goats Homestead" we can confirm that while the video doesn't explicitly show the freeze-drying process of the goat milk, it does mention that goat milk can be dehydrated and used for other purposes such as in soaps.
Here's a breakdown:
- Dehydration vs. Freeze Drying: The video uses the term "dehydrate," but freeze-drying is a specific type of dehydration process. It removes the moisture from a frozen product, resulting in a very dry final product. This implies that the underlying principle of removing water to preserve the milk is possible via freeze-drying.
- Practical Application: While the video specifies the dehydrated milk being used in soap-making, it acknowledges that the milk's properties can be preserved for later use after the water has been removed through a drying process, and thus freeze drying would be an appropriate preservation method.
Why consider freeze-drying goat milk?
- Long-term storage: Freeze-dried products can be stored for a very long time without refrigeration, making it useful for emergency food supplies or long-term storage of surplus milk.
- Reduced volume: Removing the water significantly reduces the volume and weight, which makes storage and transportation easier.
- Retains nutritional value: Freeze-drying typically does a better job than other methods of preserving nutrients and flavor.
- Convenience: Freeze-dried milk can be easily reconstituted by adding water when needed.
How to freeze dry goat milk (General Process)
While the video doesn't detail the process of freeze-drying itself, here’s a general idea:
- Pre-freeze: The goat milk is first frozen solid in a freeze dryer.
- Vacuum: A strong vacuum is applied to the frozen milk, which causes the ice to sublimate (transition directly from solid to gas).
- Condensation: The water vapor is then collected on cold condenser coils.
- Completion: The process is continued until the moisture content is significantly reduced, resulting in a shelf-stable, dry product.
