Guide to Dehydrating Food From Your Garden

When your garden is overflowing with vegetables, it’s time to kick your preservation methods into overdrive. Aside from canning and freezing, dehydrating is another method for food preservation, allowing you to save all of your harvest or extra food scraps. 

The great thing about dehydrating is that you can use this method with almost all vegetables and fruit that you grow. It doesn’t require too many tools either! 

Home food dehydration depends on three principles for success, which are:

  • Using a controlled, warm environment that can remove moisture without cooking the good. 
  • The dry air absorbs the moisture during the process
  • Air circulation takes out the moisture from the environment. 

When you dehydrate food, you remove 80-95% of moisture, which stops spoilage while retaining nutrients in the food.

  • Save Money

Dehydrating saves money, and it’s one of the cheapest ways to preserve food. You don’t need to purchase canning jars, pectin, and all of those supplies. All you need is a dehydrator, but some people dehydrate in the oven. Then, you store the food in airtight containers. 

Dehydrating lets you make things such as sundried tomatoes, dried soup mixes, spice blends, and more. Dried fruit is expensive in the store, but you can make dehydrated fruit at home with little effort. 

  • Keeps the Flavor

When you dry vegetables and fruit that you just harvested, you can preserve the flavor from peak ripeness all year-round. Drying apples in season means that you can get the apples for the best price and the best flavor, and then enjoy it throughout the year. 

  • Retains the Nutrients

Drying the food you grow keeps the most nutrients in the food as possible. Canning can degrade nutrients over time, but dehydrating sucks all of those nutrients into the dried fruit and vegetables. So, you get the most that you can. 

  • Convenience

You can make dehydrated snacks, prepare soup mixes that just need water to be added, and dried meat. Making a pot of vegetable soup becomes so easy when you have to dump in the mix and water. That’s it!

  2. Remove the cranberries in a colander.
