If you have an oven at home, you can use this kitchen appliance to dehydrate different types of foods. However, the best ones are fruits and vegetables including peaches, cherries, mushrooms, beans, and onions. So, are you ready for dehydrating foods in the oven? Just follow the tips below to start dehydrating your favorite ingredients.
How To Dehydrate Food in the Oven
Preparing foods for dehydrating
The most important factor to consider when preparing your food for drying is even thickness. When your slices are evenly thick, they will dry at uniform rate. As a result, you get equally dried foods after the dehydration process. Uneven thickness, on the other hand, may lead to spoiling during storage.
To help you achieve even thickness, it’s important to use appropriate tools. For instance, you can use a slicing device to make sure your cuts are equal in inches. Cast iron slicing device is one of the most common tools in the kitchen that has been used for two decades already and is still essential in households.
Fro dehydrating fruits such as pears and apples, this tool works more efficiently when it comes to slicing, peeling, and coring simultaneously. If you are planning to buy your own slicing device, find the product that doesn’t consist of plastic parts.
Depending on the product, peeling is sometimes unnecessary when dehydrating food. The only reason for this is that, removing the skin from your fruit helps avoid imperfections that may cause uneven cooking and poor taste. Also, if you think there are pesticides used, peeling can help eliminate the toxins.
Dehydrating foods in the oven
Oven drying slowly dehydrates food at around 140 – 200 degrees Fahrenheit (60 – 100 degrees Celsius). The oven is a good alternative if you don’t have an electric dehydrator or other means to preserve your fruits, veggies, and meat.
One of the reasons why some people don’t opt for dehydrating food in the oven is the tendency of this appliance to warm up the house. Therefore, it’s important to make sure that the oven temperature is low enough, to safely dry your food.
An oven may take at least 2 times longer than an electric dehydrator. So if you don’t mind drying in a slower method, then this is a good option for you to dehydrate your foods. Here are some helpful tips if you want to use your oven for dehydrating fruits and vegetables.
- Make sure the dial shows 140 degrees Fahrenheit or lower. You can also set the oven to “Keep Warm” to dry your food instead of cook. Check the thermostat before putting your fruits or vegetables inside the oven.
- Oven thermometers that are located beside the food often provide a more accurate reading.
- To help improve air circulation, you can leave the door open for at least 2 inches and place an electric fan near the oven to direct the heat outside.
Important things to keep in mind
Dehydrating your foods at high temperatures may kill the enzymes. However, denser foods are often capable of withstanding high temperatures so they retain the enzymes. Note that most enzymes become inactive at temperatures higher than 14o to 158 degrees Fahrenheit.
Unlike dehydrators, using the oven to dehydrate foods may take at least 8 hours. This method offers a slow process of drying which is a good factor to consider if you want a faster way to dry your harvest. However, never shortcut the time for oven drying because it will lead to case hardening wherein the outside part of the food is dried while the inside is still moist.
You don’t need to attend to your food once it’s inside the oven. That means you can do other chores while waiting for your food to dry since it’s a long process that requires more time than other drying methods. However, you can do some checking after a few hours just to make sure they are drying properly.
Ovens without adequate ventilation may need you to crack the door open a bit to avoid moisture buildup. Adjust or turn the pans after a few hours if there are hot spots in your oven to make sure the drying rate is the same. If you notice your food has shrunk and completely dry, it’s all good for cooling.
Once the food is cool, you can prepare your storage containers so you can keep it in a safe place like your kitchen cabinet. You can eat it as a snack or add to your cooking for a more delicious meal. It’s one of the most convenient ways to ensure you have what you need when you need it.
Having excess produce for your seasonal harvest can be managed with drying. It helps preserve your food so you can have it even if it’s off-season or not available in the market. Plus, dried food is more nutritious than your supermarket favorites that are mostly preserved with artificial flavors.
Aside from keeping your grocery expenses down, oven drying also provides a healthier and fun way to preserve your fruits, vegetables, and meat. So, what food are you drying today in your oven?
