Dehydrating causes a minimal affect on the nutritional value of food, according to Go Green. When you dry foods at home, you are able to monitor the temperature settings and the amount of time the heating takes place, in this way you can produce higher quality treats than by purchasing dehydrated foods from the market.
To dehydrate food you cut up the fruit or vegetable into thin slices, and then place it in the dehydrator and wait. Dipping fruit and veggie slices into lemon juice before putting them in the dehydrator may decrease browning too.
Dehydrating food is great for hikers, farmers and anyone who want to preserve produce for an extended time.
"Drying is one of the oldest methods of food preparation," says Rita Romano, author of Dining in the Raw. ¹ "Drying preserves more of the nutrients in foods than cooking because of a lower heat exposure."
