The question “What is the nutritional value of dehydrated foods?” has been on the minds of many health enthusiasts and cooking aficionados. Dehydration, a food preservation process that’s been in practice for centuries, has often been examined for its effect on the nutrient content of food. This article offers an in-depth look at the potential nutritional shifts that can occur when food undergoes dehydration, emphasizing the importance of the drying process in retaining nutrients and ensuring food safety.
As about 60% of consumers pay attention to the nutritional facts on food packages, it’s important to consider how dehydrated foods can add to our health. When we’re looking to improve our health and eat better, dehydrated food can help if we use it wisely. If we don’t, we might end up losing lots of nutrients when we eat.
Here are three things you should know about the dehydration process and how dehydrated foods can add to good health.
Dehydrating food is one of the oldest forms of preserving food. It removes the moisture from your favorite ingredients, allowing you to store them for a long time. There are many ways to dehydrate food, from the sun to your oven to an electric dehydrator or even a commercial dehydrator. Compared to fresh produce, dehydrated food retains its nutrients for a longer period and helps reduce food waste.
You can dehydrate just about any food. From colorful fruits to savory soup mixes to aromatic herbs and spices like coconut and homemade kale chips, banana chips and apple chips. Even pet treats!
Dehydrating food is a wonderful way to preserve nutrients in your food. It’s a great option if you’re on a healthy diet. Dehydrated foods are full of nutrients, including antioxidants, essential fatty acids, minerals and enzymes that are so important for our health.
Fresh fruits and vegetables are full of nutrients, but they’re robbed of theirs within just a few days of being picked. Time is not friendly to fresh fruit. Dehydrated options, however, retain their nutritional value much longer, allowing for a longer shelf life and less food waste.
Depending on which vitamins you’re hoping to get from your food, you might have trouble getting as much from dehydrated foods. If you’re looking to get more vitamin A or C, you’ll find that when they hit air or heat, the vitamin content drops. Vitamins B and C will end up in your cooking water if you end up rehydrating them that way.
You need to store dehydrated foods in a dark place, as foods might lose their content when they hit the light.
Some foods might end up with only a small percentage of their original vitamin content. You’ll get the most from biting into a fresh apple picked from a tree, but if you’re willing to add a little more to your cooking, you can get the same nutrients.
Depending on how you treat your dehydrated foods, you could end up with lower nutrients that you start with.
Sulfite treatments or sodium metabisulfite could result in lower vitamin content. If you’re worried about keeping your nutrients, blanching before you dehydrate will help keep in some of the vital contents.
If you dip your fruit in pineapple or lemon juice before you dehydrate them, you can keep some of the vitamin C they lose during dehydration. This also helps to keep them from turning brown as they’re dehydrated.
If you want to ensure that your dehydrated foods keep as much nutritional content as possible, dry them properly.
Freeze-drying foods allow for fewer nutrient loss issues than when you use a dehydrator. However, this is a much more labor-intensive process.
How you store your food will make a much greater difference in maintaining nutritional content.
After food is dehydrated, it needs to be properly packaged. After they’re cooled, they should be in a container for two weeks and then shaken every day.
If they gather condensation, they’re not dehydrated and they need to be dehydrated further. Failing to dehydrate properly leads to contamination. Contamination will cause your food to decay and problems to grow inside of containers.
Dehydrating food can be done through various methods, each with its own advantages and disadvantages. Here are some of the most common dehydration methods:
The impact of dehydration on the nutritional value of food can be multifaceted. Here’s an overview of how specific nutrients fare during the dehydration process:
Calorie Content: The calorie content of food remains unchanged during dehydration. However, as water is removed, the calories are concentrated into a smaller mass, making dehydrated food more calorie-dense than its fresh counterpart.
Fiber: The fiber content remains unaffected during dehydration. In fact, dehydrated foods may have a higher proportion of fiber in relation to their weight compared to fresh foods.
Vitamins: Certain vitamins are sensitive to heat and may be diminished during the dehydration process. Vitamins A and C, in particular, may be reduced due to exposure to heat and air.
Minerals: Most minerals remain intact during dehydration. However, some minerals may be lost during rehydration if the water used for soaking is not consumed.
Enzymes: Dehydration involves heat, and heat can deactivate some enzymes. However, the low temperatures used in home dehydration are less likely to kill enzymes compared to cooking.
The good news is that there are several ways to minimize the loss of nutrients during dehydration. Here are six effective strategies:
Pre-Treat Your Food: Pre-treating food with a solution like lemon juice can minimize the loss of vitamin C during dehydration. Furthermore, it can prevent discoloration in foods like apples and pears.
Blanch Your Vegetables: Blanching can help preserve certain nutrients like thiamine and carotene. However, it can also lead to some loss of vitamin C.
Slice Your Food Evenly: Uniform slicing helps avoid overheating or over-drying smaller pieces, which can lead to further nutrient loss.
Rotate Your Dehydrator Trays: Regular rotation ensures equal drying and prevents over-drying certain portions.
Dehydrate Food at the Right Temperature: Proper temperature control is crucial in preserving nutrients. Different foods require different temperatures for optimal dehydration.
Store Your Dehydrated Food Properly: After dehydration, the food needs to be stored properly to maintain its nutritional value. A cool, dark, dry place is ideal.
Dehydrating food can help retain its nutritional value, but it’s essential to follow some best practices to maximize nutrient retention. Here are some tips:
As cold and flu season approaches, it’s vital that everything we eat contributes to a strong immune system. If our dehydrated food doesn’t have the nutrients we expect it to, we might end up losing out on some vital nutrients we need to stay healthy.
One of the biggest benefits of dehydrated foods is that they help reduce food waste in your kitchen. By removing the moisture from your ingredients, you can store them for a long time.
Less food waste means less money spent at the grocery store and less time shopping. It’s a great way to reduce your grocery bill and keep more money in your pocket.
When it comes to purchasing dehydrated foods, read those ingredient labels! Many dehydrated foods have added salt, sugar and oils that can negate any health benefits. Look for dehydrated foods with fewer preservatives and artificial ingredients.
You’ll also want to consider how the food was dehydrated. Freeze drying is a great method that preserves more nutrients than others. Always check the storage instructions for dehydrated foods you purchase so you know how to store them at home.
Dried fruits, like fruits, are full of nutrients. Even dehydrated veggies like kale are packed with vitamins and minerals. You can still get a healthy dose of nutrients from dried fruits and veggies.
Powdered vegetables are another story. They’re made from dehydrated and powdered veggies and are a great way to add extra nutrients to your meals. Simply stir them into soups, sauces and smoothies. Dried fruits are also a great addition to smoothies.
Many dehydrated foods can be rehydrated by soaking them in water. Simply submerge them in your favorite liquid and wait a few minutes for them to return to their former texture and flavor.
You can also add dehydrated foods to soups, stews, casseroles and salads where they’ll rehydrate and add flavor and nutrients to your meals. Dehydrated foods are also a great healthy snack to take on-the-go. Simply rehydrate them and pack in your bag or lunchbox.
You can also add dehydrated foods to your oatmeal, baked goods and smoothies for an extra nutritional boost.
Cool, dried foods like snacks and pet treats can be packaged in glass jars or moisture and vapor-proof containers. Make sure to scald your glass jars by soaking them in hot water for a few minutes to remove any mildew.
Use tight seals to lock out moisture and those unwanted critters. Store your dried foods in a cool, dark, dry cupboard or pantry away from heat and sunlight. Always check packaging instructions for proper storage and handling.
Dehydrated foods are a backpacker’s best friend. They’re lightweight, packable and nutritious. If you’re on a special diet, dehydrated foods can be just as accommodating.
Whether you’re vegan, gluten-free or paleo, there are dehydrated foods that can fit into your meal plan. Just be mindful of the nutrition in your dehydrated meals. Many dehydrated meal options are made with meat and are high in protein. If you’re on a special diet, be sure to check the labels and look for certifications like gluten-free and vegan.
Dehydrated foods are not empty calories. In fact, they can be more nutritious than fresh foods if done properly and stored correctly.
You also might think dehydrated foods are not flavorful, but they can be just as tasty as fresh foods. Many times, they’re more so! And while you might think dehydrated foods are limited to fruits and veggies, think again. You can dehydrate meats, herbs and even complete meals. Dehydrated foods are very versatile and can be just as convenient. They’re easy to store and have a long shelf life. They’re perfect for busy people on-the-go.
Dehydrated food can be a healthy and convenient option, but it’s essential to follow some best practices to ensure food safety and quality. Here are some tips:
By following these best practices, you can enjoy healthy and nutritious dehydrated food while minimizing the risk of foodborne illness.
In conclusion, the answer to “Does dehydrating food change nutritional value?” is yes, but the degree of the change depends on the nutrient type and the dehydration method used. While water-soluble vitamins are affected the most, minerals and proteins remain relatively stable.
Despite the fact that dehydration can result in a loss of some vitamins, it’s crucial to remember that dehydrated foods continue to provide nutritional value. They can offer a good source of fiber, energy, and other essential nutrients.
While dehydration does alter the nutritional value of food to some extent, it doesn’t strip the food of nutrients entirely. It’s all about balance and diversity. Including a combination of fresh and dehydrated foods in your diet can help ensure you receive a broad range of nutrients and enjoy the benefits of both types of food.

Dehydrated food retains much of its nutritional value, including essential vitamins, minerals, and dietary fiber, despite the drying process. While some water-soluble vitamins may diminish, the overall nutrient density can remain high due to the concentration of nutrients in a reduced volume. Properly dried food can serve as a convenient and nutrient-rich option, offering a longer shelf life compared to its fresh counterparts.
When dehydrating food, some nutrients, particularly water-soluble vitamins like vitamin C and certain B vitamins, can be lost due to exposure to heat and air. However, the overall nutrient loss is generally minimal, and the concentration of other nutrients, such as dietary fiber and minerals, remains relatively stable. Proper dehydration techniques and storage methods can help minimize nutrient loss, ensuring that dehydrated foods retain a significant portion of their nutritional value.
