Why blanch vegetables before dehydrating?

We do this important step for certain vegetables before dehydrating for a few good reasons:

Why Blanch Vegetables?
Here Are Three Reasons

One: It’s important that we deter the food-spoiling process caused by enzymes being present in the vegetables. Blanching helps to stop the enzymatic process, which can cause the food to spoil. Additionally, blanching helps to preserve the flavor, and nutrients of the vegetables. 

Two: It aids in the actual food dehydrating process. I’ll go more into that shortly on this page.

Three: Blanching makes it easier to peel and remove the skin from the vegetables.

Blanching Keeps Vegetable Colors Vibrant

Another reason for blanching vegetables is that blanching helps keep the beautiful color of your vegetables. Your zucchini and broccoli will remain bright green! Your carrots will remain a vivid orange! You get the picture. Blanching also helps retain flavor.





What IS Blanching?

Blanching simply means dipping foods into small amounts of boiling water for a short period of time. Remember, we're not cooking the food here—so a short period of time really only means less than a minute!

Blanching Cracks Skins!

For vegetables that have relatively thick skins (that we want to keep/eat), blanching creates tiny cracks in the skins. These tiny surface cracks help dehydration to occur at a much deeper penetration level that’s more than just surface-skin deep.

For proper long-term storage, you must make sure the food you dehydrate has been “dried to the core,” if you will. Why? You don’t want to end up with moist centers! A moist center will create a breeding ground for mold. And sometimes moist centers are simply NOT visible in large pieces of vegetables with thick skins.

Of course, we can ease that problem by cutting our vegetables into similar-sized strips prior to dehydrating.





After Dehydrating: Use Oxygen Absorbers

Make sure to add an oxygen absorber to your dehydrated food packages, prior to vacuum-sealing. Oxygen absorbers do what their name implies: they absorb oxygen. This, in turn, helps inhibit mold growth, which is an essential factor for long-term food storage!
