Automated Cycle 7: Freeze-Drying Herbs

Freeze-drying herbs is an excellent way to preserve their flavor, aroma, essential oils, and nutritional value to the maximum. Properly preserved, freeze-dried herbs can have an impressive shelf life of at least 25 years if stored correctly, as outlined in our guide on proper food packaging.

Herbs are generally easier to dry compared to other foods like fruits or pastes due to their lower water content, which also speeds up the freeze-drying process.

Steps for Freeze-Drying Herbs:

1. Preparation:

   • Choose fresh herbs such as parsley, basil, mint, or cilantro. Wash them thoroughly, pat dry, and pick the leaves off the stems for the best results.

2. Loading the Trays:

   • Layer the herbs on the freeze dryer trays. You can stack several layers thick as herbs contain less water and are easier for the freeze dryer to process effectively.

3. Starting the Automated Cycle:

   • Ensure the vacuum valve and drain valve are closed.
   • Securely close the acrylic door and connect the vacuum pump.
   • From the main screen of the freeze dryer, select the 'FreezeDrying' button and then press 'Start' to initiate the automated cycle.
   

4. Packaging:

   • Once the cycle is complete and the herbs are thoroughly dried, package them appropriately. For culinary uses, packaging in airtight mason jars is ideal to maintain their original shape. If space-saving is a priority or for long-term storage, grind the herbs and/or seal them in mylar bags.

By following these steps, you can effectively freeze-dry herbs preserving their qualities for extended use. Whether for culinary projects or long-term food storage, freeze-dried herbs provide convenience and quality, keeping their characteristics intact for years to come. Enjoy the freshness and flavor of your herbs long after they've been preserved!
