Apple crisp, dried mango, and beef jerky are foods that can be made in food dryers, which dry foods at low temperatures for extended periods of time. The lack of moisture gives the foods stronger flavors, making fruits sweeter and herbs spicier, and also allows them to be stored for longer periods of time.
In addition to tasting and preserving better, homemade dehydrated snacks tend to be healthier than store-bought. They are generally made from dried whole ingredients, without additives or preservatives, and without calorie-dense ingredients such as oil or sugar. They can also be customized as desired.
Dehydration also preserves the nutrients in the ingredients better than cooking methods. Foods like kale, which is high in vitamin C, which is water soluble and heat sensitive, lose their immunity when boiled. Dehydrating at low temperatures helps retain nutrients and vitamins.

How Does a Food Dehydrator Work
A dehydrator is an electrical machine that removes water from its contents. It consists of a tray, a heating element, a vent, and a fan for circulation. The dehydrator’s heater raises the temperature inside the unit, the fan circulates the heat evenly to remove the moisture, and the tray is filled with the food to be dehydrated.
Of course, various details must be taken into consideration when actually using the dehydrator. It is not enough to cut the food, throw it into the machine, close the door, and say, “Now, let’s get to work. There is a lot of attention to detail in these details.
The dehydrator has a temperature scale to use, and you need to know what temperature is best for each food. There are schedules on how to perfectly dehydrate certain foods. There are many dehydration instruments available, so you need to know what to look for and what to avoid while hovering.
Fortunately, our interest has led to some great discoveries, and we hope we can point you in the right direction. For more information, please click here.

What types of foods can be dehydrated?
All foods can be dehydrated, including herbs and spices.
Fruits such as mango, pineapple, strawberries, plums, blueberries, apricots, kiwi, pears, grapes, and cranberries are fun ideas.
Eggplant, asparagus, tomatoes, zucchini, cabbage, garlic, potatoes, and mushrooms are good vegetables.
Flowers can be removed from the greenhouse, dried, and given as potpourri. This is a great option because the flowers can be kept outside for a long time.
The Internet and bookstores are full of recipes for creating incredibly tasty creations. For example, you can marinate and dehydrate eggplant and mushrooms and eat them as meat simulacrums. You can also marinate and then dehydrate sliced potatoes to make delicious chips. The possibilities are only limited by your imagination.

Five Simple Tips for Dehydrating Food
Here are six basic tips to keep in mind when dehydrating food.
Check the proper temperature
The temperature and time required for proper dehydration depends on the type of dehydrator you purchase and the foods you wish to dehydrate. General time and temperature guidelines, along with an estimate of the time required, are printed on the dehydrator’s label or in the owner’s manual.
Ensure that food is 95% dehydrated
Foods must be at least 95% dehydrated to be properly stored. If food becomes soft, spongy, or sticky, return it to the dehydrator for an extended time. Hard, crispy, or brittle foods are the finished product. High indoor humidity, air conditioning or strong winds will affect the dehydration time of food. The best place to place the dehydrator is in a dry, warm location with no vents or windows.

Don’t try to dry food too quickly
Don’t be afraid to over-dry. You can dry the food longer if necessary, but it is unwise to increase the temperature setting in an attempt to dry it faster. This will seal the outside and leave moisture inside, which will cause the food to spoil before you can eat it.
Preparation is important
Before dehydrating, wash all foods thoroughly with a vegetable-based antimicrobial cleaner. Wear gloves when preparing foods to avoid skin oils. Steam all low-acid vegetables for 10 minutes before dehydrating. Once steamed, wipe off the water and place in the dehydrator. Bananas and apples can be sprinkled with lemon juice to prevent browning.
Be more efficient
Just like using an oven, it is wise to turn on the dehydrator and let it warm up to the required temperature before using it, and then add the food. Prepare foods that require the same temperature and dehydrate them at the same time. It works best if all foods are cut to the same thickness and size.
Tips for Beginners
If you are new to dehydration, it is a very easy process. Just pay attention to these tips.
- Start with fresh, clean dry goods. You want to start the process with the best product possible for the best end result.
- Cut the ingredients into uniform sizes. This will ensure that everything is dehydrated evenly and at the same time.
- Check frequently. Dehydrators run very slowly, so you have plenty of time to realize that your food is dehydrated. Unlike canning and baking, everything stops as soon as you turn it off.
- If your goal is to produce shelf-stable food, you must dehydrate it completely. To find this out, place a small amount of food in a glass jar with a lid. If it fogs, the food contains too much water.
- Season lightly and taste often. If you are making something like kale chips, use salt and other seasonings carefully, as the more you use them, the more concentrated they become.

Storage and Hydration of Dehydrated Foods
During storage, care should be taken to protect dehydrated foods from heat, light, and moisture. Too many of these elements will reduce the shelf life of the food. Dehydrated foods should be allowed to cool to room temperature to avoid condensation in the package.
When storing dehydrated foods, consider using a vacuum packer. If you do not have a vacuum packer, Ziploc bags can be used, but be sure to remove as much air as possible and seal the bag tightly.
Once dehydrated foods are bagged, place them in a dry, cool, dark place. Do not place in the freezer, as you will see ice crystals forming inside. Check your inventory weekly for several weeks to ensure overall quality. If properly dehydrated and stored in a vacuum, food can last 20 years or more.
To rehydrate food, plan to add a cup of food to a cup of hot or cold water, depending on its intended use. This should be followed by rehydration for up to 4 hours.
Use the food as you would in a normal recipe. If you are cooking using a slow cooker, simply place the vegetables in the slow cooker and add the amount of water needed for your recipe and the vegetables will rehydrate on their own.

Frequently Asked Questions
Can I use my oven as a dehydrator?
Like ovens, food dryers work by circulating air at low temperatures for extended periods of time. However, instead of cooking with heat, a dehydrator extracts moisture from food and dries it so that it tastes better for a longer period of time.
Most ovens do not offer the low temperatures that dehydrators do. Some newer models offer optional dehydration, but the limited number of racks and accessories that come with most ovens are still not ideal. Larger capacity models, especially those like the June Smart Oven and Breville Smart Oven Air, can dehydrate more food at once by purchasing additional deep fryer and dehydration racks.
Is it worth it to buy a dehydrator?
A dehydrator is a useful appliance for people who care about their diet. It encourages the consumption of whole, real foods and helps eliminate food waste. It is especially recommended for parents who are trying to provide healthy snacks for their children, for those with allergies, or for those who have difficulty finding additive-free snacks at the store.
Dehydrators are also very cost-effective in the long run. You can buy products in bulk and store them, especially when they are in season or on sale. It is also a great tool for gardeners who often have excess food.
The downside of dehydrators is that they take a long time to dry food and their output is often too easy to eat up in one sitting. However, if you purchase a large dehydrator with a timer, the task can be very easy and rewarding.
How does a food dehydrator work?
A dehydrator works by using low heat and a fan that blows continuously to remove moisture from the food to create a more consistent product. Flavor is not compromised by the loss of moisture, and the machine can provide great power in a small space.
What kinds of foods can be dehydrated?
You can dehydrate just about anything, including meat (beef, salmon, turkey jerky), vegetables (beet chips, kale chips, sun-dried tomatoes), and fruit (banana chips, apple chips, fruit leather). You can even make treats that pets will enjoy, such as dog cookies. There also seems to be a renewed interest in dehydrators among raw food dieters because they extract water rather than heat.
How long do dehydrated foods last?
If dehydrated properly (as long as the water is gone), dehydrated food can last up to a year. Dehydrated, vacuum-packed, and sealed foods can last several more years.
How should dehydrated foods be stored?
All dehydrated foods should be dried and stored in clean containers in a cool, dark place to extend shelf life. Always look at the food before you eat it, and if you see mold or anything “wrong” with it, throw it away.
However, many people keep products that they still like to chew a little, like dried tomatoes, in the freezer after dehydration. Drying them until they are ready to be stored will make them too brittle.
