A Guide to Freeze Drying Watermelons: Benefits, How-To, and Uses

Watermelons are delicious and rich in vitamins A, and C, and antioxidants. Moreover, watermelon is delicious and can support the body’s hydration, boost the immune system, and promote overall health. 

But let's be honest, they're not exactly known for their long shelf life. But did you know you can preserve watermelon's taste and nutrients year-round?

Freeze drying offers a method to preserve watermelon and savor its delightful taste all year, even when not in season. 

Let's dive into how to freeze-dry watermelon at home!

The Freeze-Drying Process

Freeze-drying, also known as lyophilization, is a preservation process that involves freezing food and then removing the frozen water content through sublimation. 

During the freeze-drying process, temperature is decreased gradually, freezing the food further and creating a vacuum environment. As the temperature decreases, the frozen water within the fruit sublimates, leaving behind a freeze-dried product with a crisp texture and concentrated flavor.

This gentle drying process, unlike traditional methods, keeps the watermelon's flavor and nutrients intact. So, you can enjoy the refreshing taste of summer anytime, anywhere!

1. Prep the Watermelon

  • Wash and dry the watermelon thoroughly.
  • Slice it into small, uniform pieces. This helps the freeze-drying process happen faster and more evenly.
  • Pre-freeze the watermelon cubes at -10°F (-23°C) until completely frozen solid.

2. Load the Freeze Dryer Trays

  • Spread the watermelon slices in a single layer on your freeze-dryer trays.
  • Make sure they're not touching to allow for proper air circulation.

Tip: Freeze the watermelon slices overnight before transferring them to the freeze dryer.

3. Freeze-Drying Time

  • Set the freeze dryer to the default settings:
    • Freezing Temperature: -10°F (-23°C)
    • Initial Freeze Time: 1 hour extra (extended to ensure thorough freezing)
    • Drying Temperature: 125°F (52°C)
  • Run the initial freeze dry cycle with the default drying time setting.
  • After the initial cycle, add an extra dry time of at least 12 hours.
  • Check periodically and if still chewy/undried after 12 additional hours, run another 6-12 hour dry cycle overnight.

The finished product should be dry and crisp, easily breaking apart when touched. Check on it occasionally to monitor progress.

4. Proper Storage is Key

Once freeze-dried, store your watermelon properly to maintain its quality and shelf life.

  • Vacuum Sealing: Vacuum sealing the freeze-dried watermelon in airtight bags or containers is the most effective method to prevent moisture absorption and keeps it fresh for a longer time.
  • Airtight Containers with Desiccant: Alternatively, you can store the freeze-dried watermelon in airtight containers with desiccant packets. These packets help absorb any remaining moisture.

Regardless of the storage method, keep the containers in a cool, dry place away from direct sunlight for optimal storage conditions.

Now you have delicious freeze-dried watermelon to enjoy as a snack or add to recipes anytime!
