Why Dehydrate Food?

Question: "Why dehydrate food?"
Answer: So you have emergency food on hand when the grocery stores have run out. Or when another pandemic like Covid-19 hits (heaven forbid).




But why the method of dehydration over freezing, or canning? It's the time-factor. And three important reasons why dehydration works better.

In order to store food properly for long-term storage, you need to keep three things at bay:

   1. Air

   2. Light

   3. Water

When those three things are addressed, your success of storing food for long-term will be greatly increased.

What's Wrong with Freezing Foods?

So, what's wrong with freezing food? Not only do you have to have electricity to keep the foods frozen, you need freezer-storage space. But what happens when the power goes out? You can't run one of those noisy compressors for ever. And more often than not, those packaged frozen meals get 'freezer burn' which is simply a case of air being converted to ice.  This brings me to point 1: Air.

When dehydrating foods, we remove the air using a food vacuum-sealer. Point 1 'done.'

Point 2: Light. Keeping foods away from direct light also prolongs its shelf-life. Storing our dehydrated food in Mylar bags takes care of that issue.

Regarding point 3: Water ... when you freeze foods, the water is in there, and again, you need electricity to keep the food frozen. When we dehydrate food, we're taking the water out. And to make sure your foods stay as dry as possible, we add oxygen absorbers to the vacuum-sealed bags.

Save Cash by Dehydrating Foods

A great way to save cash is by dehydrating fruit and vegetables. Fact: you do not have to store the fresh foods in the refrigerator for days and weeks at a time. When the foods have been dehydrated they can last for years without electricity – and that's a great energy savings right there.

Affordable and Easy to Do

Another reason why you should dehydrate food: It's affordable and very easy to set up at home. Simply visit our dehydrator page and/or check out dehydrator reviews online and choose which dehydrator suits your home situation best.

If you are a large family, you may choose a dehydrator with the capacity to have nine trays dehydrating all at once. For just the two of you, maybe a simple four- or five-tray dehydrator would be sufficient.

There are many brands of dehydrators – some have stackable trays and some have trays that pull-out like a chest of drawers. I have one of each type of dehydrator. I have not found one to be better than the other but I have found unique purposes for each. I have a Nesco dehydrator and an Excalibur dehydrator.

The pull-out trays can allow the dehydrator to be used for proofing bread dough by simply leaving the bottom tray in and omitting the trays that would be above it.

Stack-able Benefits

The benefits of the stack-able dehydrator is if you only need to use four trays versus six, you can do that without the nagging thought of the wasted space using up expensive electricity! The next step is to purchase a vacuum sealer machine. Its purpose is twofold:

  • to draw the air out of the bag
  • to seal the vacuumed bag

You could call it a day right there or go one step further and protect your dehydrated packages by placing them into Mylar bags – made out of shiny un-tearable material – which keeps out light, moisture, air, and yes, bugs – depending on where you intend to store them, i.e. the garage, for instance.

The Mylar bags are also sealed but there is no need to vacuum them. Simply use a sharpie pen to write the contents on the bag and date it.

Space Savings Too

A different kind of savings can be achieved and that is in the way of space saving!

Eight whole bunches of celery can be stored in one quart mason jar! Can you believe that? And it takes no electricity – great energy savings - and no fridge space to store it either!
