Understanding Freeze-Drying
Freeze-drying, also known as lyophilisation, is a method of food preservation that removes moisture from the food by freezing it and then reducing the surrounding pressure to allow the frozen water in the food to sublimate directly from solid to gas. This process maintains the nutritional integrity and flavour of the food, making it a preferred choice for pet treats.

Step 2: Freeze-Drying
- Load the Machine: Transfer the frozen liver slices onto the trays of your freeze-dryer. Ensure the pieces are spaced apart to allow adequate airflow.
- Set the Machine: Follow the manufacturer’s instructions for setting the correct temperature and time. Generally, the process takes between 24 to 48 hours.
- Monitor the Process: Keep an eye on the machine periodically to ensure it is functioning correctly.
Step 3: Post-Drying
Once the freeze-drying cycle is complete, remove the trays from the machine. The liver should be completely dry and brittle to the touch.
Storing Freeze-Dried Beef Liver
