First off, why dehydrate vegetables or foods in general? Because dehydrating food reduces its moisture content to between 5-20%, at which range the bacterium that is causing food decay can’t survive. It is a great way of preserving food that will not only make it last longer but will retain its delicious taste at the same time. You can practically dehydrate anything including meats, fruits, herbs, and vegetables (including raw vegetables and some cooked ones). Although, our list here particularly focuses on the best vegetables to dehydrate.
But before that, you may be wondering what are the different methods of dehydrating food. You can use food dehydrators, oven drying, room drying, and sun drying. If you experience mostly dry weather in your location then sun drying is a great option for you. Otherwise, it’s best to use oven or food dehydrators instead. Check this list of the top 5 food dehydrators out there if you don’t have one yet.
Dehydrated food retains most of its nutritional value. Nutritional changes occur of course. For instance, some of the thiamin, riboflavin, and niacin are lost during blanching but good retention happens when the water used to rehydrate is also consumed. Same with minerals, some may be lost during rehydration if the soaking water is discarded. Calories and fiber don’t change, however. Iron is also not destroyed by drying. To ensure the best retention of nutrients, store dried fruits in cool, dry, and dark places. It’s best to consume them as well within a year.
Aside from the fact that dehydrated vegetables are healthy and nutritious because it’s all-natural, it’s also a great snack idea, delicious ingredients in cooking, and a hassle-free go-to side dish. See more benefits of dehydrated foods at the end of this article if you still need convincing about the importance of dehydration. For now, let’s go over the list of the best vegetables to dehydrate.
