Food dehydrators are more effective at removing the moisture from food without cooking it, leaving you with a healthier nutritious treat that doesn’t have to be heated up or cooked first. Foods keep a higher nutritional value and a lower risk of being overcooked when using a fruit dehydrator as opposed to an oven. Additionally, some foods may break delicately if they are overworked in the process of being dried, whereas baking can help retain those flavors and textures if baked properly.
