Instead of canning or freezing food to preserve it, you can dehydrate food. Dehydrating food is very inexpensive and requires less storage space than canned foods, plus there is no need for a freezer. If you will be dehydrating food at home, it will require some amount of time and you will have to know what you are doing for the process to be done properly.
The good news is, dehydration hardly affects the nutritional content of foods. The drying process involves removing moisture from food, which is crucial for preserving its nutritional value and flavor. The length of time it takes will vary depending on factors such as water content, sugar content, food size, etc. To remove water from food, there are three main methods that are used.
They include dehydration by the sun, in an oven or using a dehydrator. All three methods are quite effective; however, a dehydrator is the quickest and is more cost efficient than using an oven.
Dehydrating food is a fantastic way to preserve your favorite foods for backpacking and camping trips. By removing the water content, dehydrated food becomes lighter and more compact, making it easier to carry. This method of food preservation can be done at home using a food dehydrator or even in your oven.
One of the primary benefits of dehydrating food is the significant reduction in weight and volume, which is particularly useful for outdoor enthusiasts. Additionally, dehydrated foods have an extended shelf life, allowing you to store them for longer periods without worrying about spoilage. The dehydration process also helps preserve the nutrients and flavors of the food, ensuring that your meals remain tasty and nutritious.
When it’s time to enjoy your dehydrated meals, rehydration is a breeze. Simply add boiling water to the dehydrated food, and within minutes, you’ll have a delicious and convenient meal ready to eat. This makes dehydrated food an excellent option for backpackers and campers who need lightweight, easy-to-prepare meals on the go.
Dehydration is a scientific term and involves a scientific process.
The human body has a love/hate relationship with it. Your body hates how it feels when it’s dehydrated but loves the idea of dehydration because it means a ready food supply.
In simple terms, dehydration is the process of removing water from a food product. The end goal is food preservation. Even more important is the ability it gives you to inhibit the growth of bad bugs or microorganisms.
Your reward is an ample supply of tasty food without worrying about eating mold or bacteria.
Removing moisture from foods makes them smaller and lighter.
Dehydrated foods are ideal for backpacking, hiking, and camping because they weigh much less than their non-dried counterparts and do not require refrigeration. Drying food is also a way of preserving seasonal foods for later use.
Food dehydration is an ancient practice probably used by prehistoric people as a way to dry seeds using the solar dehydration method. Thankfully modern man can preserve food faster and safer with a dehydrator. The process is simple yet fascinating.

The dehydrator has a fan, which pushes the moist air out of the dehydrator through air vents.
Our banana should take about 6-8 hours but each type of food has its own dehydration time-table. At the end of the dehydration process, your food should have less than 20% of the water content you started with.
Food drying is a method of preserving food by reducing its moisture content, which helps extend shelf life and prevent harmful bacterial growth.
The way you prepare foods for dehydration determines the finished product you will receive and hence what you will end up consuming after rehydration. Here are some tips you need to know as you prepare your food for drying.
Clean and dry all surfaces, equipment, and hands before starting the dehydration process. Sanitize hands and containers before handling food for storage. Use a clean and dry station to prevent contamination.
Uniform cutting is important for even drying. A mandoline or egg slicer can be useful for cutting ingredients. Pretreatment can help retain color and flavor, improve rehydration time and texture, and increase shelf life. Ascorbic acid, fruit juice, and sulfite dips can be used for pretreatment.
Selecting the right food dehydrator can seem overwhelming, but focusing on a few key factors can simplify the process. Dehydrators range in price from $30 to several hundred dollars, so it’s essential to consider your budget and how much food you plan to dehydrate.
A dehydrator with more surface area is ideal if you plan to dehydrate large quantities of food. Square trays are generally more efficient than round ones with cutouts in the middle, as they hold more food. While a timer is a useful feature, it’s not essential. However, a fan for even heat distribution and multiple temperature settings are crucial for consistent results.
For those interested in making fruit leather, sauces, or soups, nonstick sheets or parchment paper are necessary to prevent sticking. By considering these features, you can choose a food dehydrator that meets your needs and ensures successful food dehydration.
As mentioned earlier, there are three main methods of dehydrating foods. All methods are equally effective and can result in perfectly dried foods. The method you use is totally dependent on your preferences, although the food being dried may play a part in the method used.
Here’s a little detail on each method.
Fruits and vegetables are popular choices for dehydrating, such as apples, bananas, and carrots. Most vegetables should be thinly sliced or cut into small pieces. Fruit can be sliced thin, cut into small pieces, or left whole. Pretreatment with ascorbic acid or fruit juice can help retain color and flavor.
Lean meats can be dehydrated if cooked to a safe temperature. Dehydrate at 145F until completely dry. Grains, legumes, and pasta can be dehydrated to save weight and cooking time. Cook rice and grains as usual, then dehydrate at 145F until completely dry.
The amount of time it takes to dehydrate food depends on several factors:
Regardless of the method used for dehydration, you need to know when the food is dried. The best way to determine this is by touching it. It should feel hard, sticky or even moist. Check again once the food has cooled.
When storing dehydrated food, it is important to use airtight containers to prevent moisture and pests from compromising its quality. If you are unsure if it is completely dry, continue drying it. Once you are sure it is completely dry, allow the food to cool to room temperature, and then it is time for storage.
Rehydrating dehydrated food is a straightforward process that requires water, heat, and a bit of patience. Generally, you’ll need equal parts water to food and about 15-25 minutes to reconstitute your meal. Here’s a simple guide to help you rehydrate your dehydrated meals:
This method ensures that your dehydrated meals are ready to enjoy with minimal effort, making them perfect for outdoor adventures or quick, convenient meals at home.
When dehydrating food, it’s crucial to follow safety guidelines to ensure the quality and shelf life of your dehydrated foods. Start by washing your hands thoroughly before handling any food, and make sure all equipment and surfaces are clean and dry.
Using a food thermometer can help ensure that the food is heated to a safe temperature during the dehydration process. Once your food is dehydrated, store it in airtight containers to prevent moisture and pests from compromising its quality. Ideal storage conditions include a cool, dry, and dark place.
For added protection, consider using vacuum sealing or mylar bags with oxygen absorbers to prevent oxidation and spoilage. By following these precautions, you can enjoy safe and long-lasting dehydrated foods.
Dehydrating food can sometimes present challenges, such as uneven drying, over-drying, or under-drying. Here are some tips to troubleshoot these common issues:
Always refer to the manufacturer’s instructions and guidelines for your specific dehydrator model. By addressing these common issues, you can ensure successful and efficient food dehydration every time.
Rotate dehydrator trays to ensure even drying and prevent hot spots. Rearrange food on trays to expose more parts to airflow and speed up drying. Dry extra vegetables separately to preserve color and texture. Cut fruits and vegetables into similar sizes to ensure even drying. Don’t overload dehydrator trays, as this can increase drying time.
Bananas and apricots are the go-to foods most people start with when they’re learning how to dehydrate food. Strawberries, peaches, and apples are popular too. But what about cantaloupe?
Yes, it’s a thing! People who dehydrate cantaloupe say it tastes like candy and melts in your mouth.
Fruits and dehydration go great together but don’t forget about veggies!
Don’t let your tomato harvest go to waste. Tomatoes are one of the easiest foods to dehydrate and you can use every part of them except the stems. Say “hello” to tomato powder.
Since the holiday season is here, don’t forget cranberries. Cranberries show up once a year in most parts of the country. Get them while you can and dehydrate several bags.
Choosing foods compatible with a food dehydrator isn’t difficult. Most fruits and vegetables work well. But why not learn to dehydrate meat?
Create jerky! No more wondering what to do with your venison and elk from this year’s hunting season.
When dehydrating meats, it is important to use lean meats to prevent fats and oils from going rancid and ruining the overall quality of the dehydrated meals.
During dehydration, the nutritional value of food remains unaffected for the most part, and if the food item is ‘home dried’, even less damage is done to the nutrient content of the food. This is because home drying usually involves less harsh temperatures.
Actually, the nutritional value of a food item is more likely to be affected if it is frozen or canned. Freezing and canning involve much more extreme temperatures, which affects nutrient content.
Several tests have been done on foods that have been dried, and results show that the nutrient most likely to be affected is vitamin C. All other nutrients are retained because they are not very heat sensitive. On the contrary, vitamin C is an air soluble nutrient and some of it may be lost from the cut surface of the food item.
Apart from preservation, there are other reasons why you may lean towards dehydrating a food item.
Dehydrating food is a simple and cost-effective way to preserve food and reduce food waste. With the right equipment and techniques, you can dehydrate a variety of foods, including fruits, vegetables, proteins, and grains. Proper storage and rehydration techniques can help extend the shelf life of dehydrated foods. Dehydrating food is a great way to preserve your harvest and reduce food packaging.
