Destroy Nutrients?

Does dehydrating food destroy nutrients? It’s a great question.

So...
Does Dehydrating Food Destroy Nutrients?

According to this post from the University of Missouri, Vitamins A and C can be destroyed by heat and air.

But let's not forget this: heating food by baking, boiling, broiling, and grilling ALSO destroys nutrients! Only by eating raw fruits and vegetables do we get to enjoy their full nutritional value.

Easily Rectify Vitamin Loss

The loss of Vitamins A and C through heat and air is a bit of a bummer because using heat and air is the primary way of dehydrating food! This vitamin loss is easily rectified by taking a daily vitamin supplement.

On The Other Hand:

But… the lower the temperature you dry vegetables at, the more nutrients they retain. That makes sense, right?

Fruits and vegetables are dehydrated between 125°F and 135°F (or per your food dehydrator's instructions).

My one exception is Mushrooms. They are dehydrated at 90°F for Excalibur dehydrators, and 95°F for Nesco dehydrators - for two to three hours THEN set the temperature to 125°F and dry for the remaining time.

Some Prep Steps May Affect Nutritive Value

When dehydrating certain vegetables, we need to blanch them. Read how and why here.

Blanching will also result in a loss of Vitamin C, B-Complex—and water-soluble minerals. Again, taking a daily vitamin supplement will more than make up for the vitamin and mineral loss.

For those of us who are rightly concerned with our sugar intake, please bear in mind that dehydrating fruit (that are high in natural sugars) will result in an even higher sugar concentration after dehydrating!

Why is that?  Keep reading!

Sugar Content Increases AFTER Dehydration

When you remove the water from sugar-laden foods, you're left with an even more condensed version of that food, sugar-wise. Read our post on The Pros and Cons of Dried Fruit which goes into details of dried fruit and its sugar content.

When we dehydrate food, we remove the water that’s inside our fruits (and vegetables) in an attempt to kill micro-organisms so the food won’t spoil as quickly (like they do when fresh). In an effort to also combat food spoilage, we use oxygen absorbers.

The job of an oxygen absorber is to inhibit mold growth while your foods are in (long-term) storageafter the foods have been dehydrated—and are ready to be vacuum-sealed and then stored in Mason jars (shown below) or in food vacuum-sealer bags.

Back to the Sugar Content in Fruit...

Back to the sugar content in fruit: What we are left with after dehydrating is the fruit minus water. Fruit shrinks. So what you’re thinking?

When the fruits shrink after dehydrating, it means there’s a strong chance that you’ll want to eat more of it (due to it being smaller)—and that’s where portion control for dried fruit especially—has to come into play.

Now then, if only dehydration would take out the sugar too, we’d all be a lot healthier.

Having (Enough) Food On Hand

Don’t allow the above information regarding the loss of some vitamins to deter you from dehydrating food. What we are trying to achieve is having enough food in your pantry.

When the “stuff” hits the fan, there’s nothing worse than rushing out to your grocery store to stock up, only to be greeted by empty shelves. Get ahead of the game by keeping your food pantry full, whatever the reason or season (as my site slogan goes).

Did you know, when natural disasters hit (earthquakes, hurricanes, etc.) the average family has only enough food in their refrigerator and pantry to last for 3 days... that's only nine meals? Don't let this happen to your family.
