What is Freeze Drying?

This leaves the food dry, significantly reducing its weight, but retains most of the nutritional value and flavor of the fresh product.

Steps to Freeze Dry Bananas
Preparing the Bananas
Before you start the freeze drying process, it's crucial to prepare the bananas properly. Peel the bananas and slice them into thin pieces. This allows the freeze drying process to work more effectively.
Freeze Drying Process
Step 1: Freezing
Place the sliced bananas in your freezer until they're fully frozen. This step prepares the bananas for the freeze drying process.
Step 2: Creating a Vacuum
In the next step, the bananas are placed in a freeze dryer, which creates a vacuum around the food. This allows the water in the bananas to evaporate directly from a solid to a gas, bypassing the liquid phase.
Step 3: Adding Heat
The freeze dryer then gently adds heat to the bananas, which encourages the water in the bananas to evaporate.
Step 4: Final Drying
During the final drying phase, the last bits of moisture are removed from the bananas, ensuring they're completely dry and ready for storage.
