The most common question we get asked at Best Home Preserving is “What is the best dehydrator for jerky”?  After all, jerky is one of the tastiest and healthiest snacks you can lay your hands on, especially when it is home made. 

Not just that, when you make jerky in a dehydrator at home you have a delicious protein source to take with you on busy days that isn’t full of additives and preservatives.

Food dehydration, which works by eliminating moisture from food, is a trusted home food preservation method that significantly increases the shelf-life of foods.  It eliminates one of the most critical materials for bacterial growth – moisture.  Plus, dehydrated foods simply make great snacks.
