Tips to Remember BEFORE Storing Microgreens

Microgreens are known as superfoods for their nutritional value. 

According to a study by professors at the University of Maryland, microgreens tend to have higher concentrations of vitamins, proteins, and other nutrients than mature vegetables.

So, the fresher the microgreens are, the more nutritious they are.

However, most people don’t consume microgreens in large proportions. Thus, you need to know how to store microgreens longer – without losing their nutrients.

Here are a few things to remember before storing your microgreens.

  • Microgreens should be healthy and fresh, not wilted.
  • They must not be damaged during harvesting.
  • Do not store wet microgreens; if they’re, they will rot.

If you are growing microgreens without soil, you will have an easy time harvesting. However, if you have a soil-grown harvest, please ensure there is as little soil as possible on the microgreens. 

Once you harvest the microgreens, quickly put them in an air-tight container.

At room temperature, microgreens tend to become dry.

How Do You Store Fresh Microgreens?

Under proper conditions, the microgreens’ shelf life is up to 7 to 10 days. But keep in mind: the fresher the harvest, the more nutrients you will get.

Microgreens must always be stored in a fridge. Cool conditions are ideal for extending their shelf life and retaining their structure longer.

Here are the best practices for storing your microgreens properly.

Use Ceramic Materials to Harvest

While harvesting your microgreens, use scissors or knives made from ceramic. The material is non-toxic and lightweight, which provides easy agility while chopping your greens.

Set the Temperature Right

No matter what bags or containers you use to store microgreens, you should always put them in the fridge.

The ideal temperature of your fridge should be between 1.66° C to 4.44° C (35° F-40° F).

Different temperatures lead to different shelf life. A study report published in the Journal of Young Investigators states that microgreens stored at 50°F demonstrated a shelf life of 7-14 days, but if the temperature is reduced to 40°F, the shelf life increases to 14-21 days.

Never freeze your microgreens. Putting your microgreens in the freezer might make them dry. Also, if they freeze, you must thaw them before eating them.

This thawing can damage the texture of your microgreens, and you will lose that crunch – and the delicious taste.

Irregular temperatures and excess moisture are two of the biggest reasons that might lead to mold growth in your microgreens. So, avoid opening your fridge multiple times.

You can use a mini-fridge to store the microgreens separately.

Home Remedies If Microgreens Dry Up

Sometimes, things can go wrong even if you do everything right. In such cases, follow these quick home remedies.

  • Some gardeners suggest keeping a damp paper towel inside your bag if your microgreens are getting dry in the fridge.
  • You can also keep the bag a little open – just a little – for optimum air circulation.
  • Keep the microgreens away from excess moisture, and make sure the air circulation is optimum.

Remember that microgreens should always be refrigerated but not frozen. Otherwise, they will get soggy and rot the moment they unfreeze.
