Microgreens are a popular choice for adding a burst of flavor and nutrients to any dish. They are small, tender, and delicate, which makes them prone to spoilage if not stored properly. Dehydrating microgreens is a great way to extend their shelf life and retain their nutritional value. In this article, we will explore three different methods for dehydrating microgreens: using the sun, an air fryer, or a dehydrator.

How to Dehydrate Microgreens with The Sun

Dehydrating microgreens with the sun is the oldest method used, and it takes the longest. However, it can be done if you live in a climate where the sun is shining throughout the entire day, and the air is dry. Here are the steps for dehydrating microgreens with the sun:

  1. Harvest your microgreens in the morning when they are at their freshest.
  2. Rinse your microgreens in cold water and dry them thoroughly using a salad spinner or paper towels.
  3. Spread your microgreens out evenly on a baking sheet or a tray.
  4. Place the tray in an area where it can receive full sunlight throughout the day.
  5. Let the microgreens dry in the sun for 3 to 4 days, turning them occasionally to ensure even drying.
  6. Once the microgreens are completely dry, store them in an airtight container in a cool, dark place.

  1. Preheat your air fryer to its lowest setting.
  2. Rinse your microgreens in cold water and dry them thoroughly using a salad spinner or paper towels.
  3. Spread your microgreens out evenly on the air fryer basket or tray.
  4. Place the basket or tray in the air fryer and set the timer for 1 to 2 hours.
  5. Check the microgreens every 30 minutes and shake the basket or tray to ensure even drying.
  6. Once the microgreens are completely dry, let them cool down and store them in an airtight container in a cool, dark place.

Note: This method is more reliable than using the sun, but it may not be as efficient as using a dehydrator.

How to Dehydrate Microgreens with Electric Dehydration

There are several ways to dehydrate microgreens, including air drying, convection drying, heating (oven), [3]. and microwave-vacuum drying [1]. However, electric dehydration is the easiest and most efficient method for drying and preserving microgreens.

dehydrating microgreens is an affordable way to extend their life and make use of them in various ways [2]. Dehydrated microgreens can be used in soups, stews, salads, and smoothies. Soak and Soil also confirm that microgreens can be dehydrated like any other vegetable, and dehydrating them makes storing microgreens easier to prevent waste [3].

To dehydrate microgreens using an electric dehydrator, start by washing the microgreens thoroughly and patting them dry with a paper towel. Arrange the microgreens on the dehydrator trays, making sure they do not touch each other.

Set the temperature of the dehydrator from 95°F to 115°F and let them dry for about 4 to 6 hours. The drying time may vary depending on the type of microgreens, the dehydrator, and the humidity level. Once the microgreens are completely dry, store them in an airtight container in a cool, dark place [1].

In conclusion, dehydrating microgreens is an excellent way to preserve their nutritional value and extend their shelf life. Electric dehydration is the easiest and most economical method for drying and preserving microgreens.

How to Dehydrate  Microgreens Using Convection Drying 

Convection drying is an effective method for drying microgreens, and it involves the use of heat and air circulation to remove moisture from the greens. This process helps to inhibit the growth of microorganisms that cause spoilage, and it ensures that the microgreens retain their nutritional value and flavor. Here are some steps to follow when using a convection oven to dry microgreens.

  1. Prep the microgreens: Wash the microgreens thoroughly and remove any damaged leaves or stems. Then, pat them dry with a clean cloth or paper towel.
  2. Remove excess moisture: Spin the microgreens in a salad spinner until they are as dry as possible. This will help to reduce the drying time and ensure that the microgreens dry evenly.
  3. Arrange the microgreens: Place the microgreens on a drying rack, making sure that they are arranged in a single layer without touching or overlapping. Layering the microgreens too thickly can lead to uneven drying and spoilage.
  4. Set the oven: Preheat the oven to 140°F. This temperature is ideal for drying microgreens as it ensures that they do not lose their nutritional value or flavor. At higher temperatures, microgreens may start to lose their tasty oils [3].
  5. Dry the microgreens: Place the microgreens in the oven and dry them for 1-3 hours. The exact drying time will depend on the thickness of the microgreens and the oven’s air circulation. It is important to check the microgreens regularly to ensure that they do not become over-dried.
  6. Store the microgreens: Once the microgreens are fully dried, remove them from the oven and let them cool completely. Then, store them in an airtight container in a cool, dry place. Properly dried microgreens can last for up to 6 months.

Overall, convection drying is an effective way to dry microgreens as it ensures that they retain their nutritional value and flavor while inhibiting the growth of microorganisms that can cause spoilage. By following the above steps, you can easily dry your own microgreens at home using a convection oven.

How to Dehydrate Microgreens with Microwave-Vacuum Drying [1]. 

Microwave-vacuum drying is a promising technology for drying food products, including microgreens. Microgreens are young vegetable plants that are harvested after the cotyledon leaves have developed but before the true leaves have emerged.

They are used as a popular ingredient in salads, and sandwiches, and as a garnish in various dishes. Microwave-vacuum drying combines the advantages of microwave and vacuum drying, resulting in a higher drying rate and improved product quality compared to traditional vacuum drying [1].

A domestic microwave oven can be modified into a microwave vacuum dryer for drying microgreens [1]. In this process, the microgreens are placed in a polypropylene container, which acts as a vacuum chamber, and then placed inside the microwave cavity.

The vacuum chamber is connected to a vacuum pump, which removes the air and creates a vacuum inside the chamber. Then, microwave energy is applied to heat the product, and the water is evaporated from the microgreens. The moisture evaporated from the product is then removed by the vacuum, resulting in a faster drying process [1].

One of the benefits of microwave-vacuum drying for microgreens is that it can dry the product at a low temperature, which can preserve the color, flavor, and nutritional content of the product [1]. Additionally, microwave-vacuum drying can reduce the drying time by up to 50% compared to traditional vacuum drying [2]. This can result in higher throughput and increased efficiency.

Microwave-vacuum drying is a promising technology for drying microgreens. It combines the advantages of microwave and vacuum drying, resulting in improved product quality and faster drying times compared to traditional vacuum drying [1]. Its low-temperature drying process can help preserve the color, flavor, and nutritional content of the product [1]. Therefore, it can be a useful technology for the food industry, especially for the production of high-quality dried microgreens.

How to Dehydrate Microgreens with Freezer Drying 

Freeze drying is a popular preservation method that can be used to extend the shelf life of various food items, including microgreens. Home freeze drying can be accomplished using a freeze dryer machine, which works by freezing the food to a very low temperature and then removing the moisture through sublimation. Here is a detailed guide on how to home freeze-dry microgreens using the information provided in the search results:

  1. Wash and prepare the microgreens: Start by washing the microgreens under clean running water to remove any dirt or debris. Let them air dry for a few minutes to remove the majority of the moisture. Then, chop them into ½ inch sections so that they are not stringy when you thaw them.
  2. Spread them out on a baking tray: After chopping the microgreens, spread them out on a baking tray. Be sure to leave some space between each piece so that they can freeze evenly.
  3. Freeze the microgreens: Put the baking tray in the freezer for 1-2 hours, or until the microgreens are completely frozen.
  4. Freeze dry the microgreens: Once the microgreens are frozen, you can start the freeze drying process. If you have a home freeze dryer machine, follow the manufacturer’s instructions to freeze dry the microgreens. Depending on the machine’s size and capacity, you can freeze dry up to 1,450 pounds of fresh food per year with a medium freeze dryer or up to 2,500 pounds of fresh food per year with a large freeze dryer [3].
  5. Store the freeze-dried microgreens: Once the freeze drying process is complete, store the microgreens in an airtight container. They can be stored at room temperature for up to a year, or in the freezer for even longer.

Freeze-drying microgreens can help you preserve them for a longer period of time while retaining their nutritional value and flavor. By following the steps outlined above, you can easily home freeze dry microgreens using a freeze-dryer machine.
