The dehydrated foods and fresh foods comprise of several similar health benefits, but both of them differ marginally in the mineral and vitamin content. Both fresh and dried vegetables and fruits offer you lots of fiber and antioxidants which are useful for your health. On the other hand, in the dehydrated fruit, a small proportion of vitamins get lost during the drying process.
Do Dehydrated Foods Possess Same Nutritional Benefits Which They Have in Raw Form?
Well! The answer to the above question depends upon the types of spices and herbs which you are taking. For example, Cinnamon is used in lots of dishes for adding flavor but in dried and powdered form. Similarly, the ginger and garlic can be utilized either in dried or in fresh form whatever suits you. In both manners, this food gives you the inflammatory benefits.
Thus, we can say that in the case of such above herbs and species the nutritional value of the food does not get vanished. In fact, they offer you lots of health benefits along with the delicious flavor.
How Is Nutritional Value Lost in the Dehydrated Food?
Well! The nutritional value of the food does get reduced after the drying process. We will make you more clearly at this point with the help of an example; let's take basil in the fresh and dried form both.
- Fresh Basil

- Dried Basil

Now, from the above example, it is clear that lots of nutrients get lost drying the drying process, but the ORAC value of both the forms remain almost same. It also shows that both are a major source of antioxidants which is good for our health.
What Types of Nutrient Gets Lost During the Drying Process from the Food?
There are lots of different kinds of nutrients which gets lost at the time of drying food. We will talk about them one by one in the below article:
As per the research, lots of minerals are found in higher quantities in the fresh foods as compared to the dried fruit. For example, in 1 cup of fresh apple, you will get 8 mg of calcium, 14 mg of phosphorus and 6 mg of magnesium whereas, in 1/4th cup of dried apple, you will fetch 3 mg of magnesium, 3 mg of calcium, as well as 8 mg of phosphorus. It shows that the fresh food has more content of minerals than the dried food.
Important TipIf you use the blanching method which mainly designed for retaining the original color of the fruit, you can save little minerals to some extent.
The vitamins like vitamin B, vitamin C, thiamin, vitamin A, and Folate got decrease when you dehydrated the raw food. We will take one example here also. Let's take one fresh apple. In the natural form, it contains four micrograms of folate and 5.8 milligrams of vitamin C. In the 1/4th cup of dried apple, only .8 milligrams of vitamin C left without any folate.
Important Tipon some occasions, few people add sulfur in the dried fruits, so that it does not turn to brown color. But with this way, you can also maintain more content of the vitamin A and vitamin C., But you should remember that with the addition of sulfur the thiamine also gets destroyed in the food.
Lots of Vitamins A and C gets reduced in the course of drying process as they destroyed by heat and air. For example, if you cut one piece of fresh fruit, it will start losing its beneficial nutrients as soon as the fruit comes in contact with the air, especially, the Vitamin C.
Every time you heat your food, lots of enzymes also get lost. But if you dry the food in lowest temperature, then it will reduce fewer enzymes as compared to the standard heating of the food.
Is There Any Way Which Prevents the Nutrients Loss at the Time of Dehydration Process?
Yes, of course, you can save the nutrients of the food from getting reduced at the point of the drying process. The following are the ways and tips which will help you in retaining the more nutrients in the food:
Right Temperature Drying
One of the easiest ways to preserve nutrients in the food is to dehydrate them at the correct temperature. You can use the electric food dehydrator for this purpose instead of the conventional mode of drying. In the electric dryers, you have full control over the temperature which helps in reducing the loss of nutrients forms the food.
You can also follow the below standard heat references for home drying:
Name of the food
95 degrees F
Nuts and seeds
105 degrees F
Fruit and vegetables
135 degrees F
160 degrees F
135 degrees F
With the help of pre-treating, you can save lots of nutrients in your food. You just have to dip the fruit and vegetables in the citric acid or lemon juice. It not only protects your food from turning brown but also preserves the vitamin C and vitamin A in the food. But unluckily in this method, the thiamine also gets reduced in dehydrated food.
By doing the blanching of the food, you can preserve the carotene in the food. But the side effects of the process are that the content of the Vitamin C also gets reduced but in the lesser amount. The steam blanching is more beneficial than the boiling water blanching as fewer nutrients get loose under that method.
- Avoid Direct Sunlight
You must not keep the dried food under the direct sunlight. They must store in a dark place, so that content of nutrients in the food does not get affected.
- Slice Food Uniformly
The food should be sliced in equal sizes so that it does not over-heat or over-dry. The over drying can reduce lots of nutrients from the food. With the help of a good slicer, you can do the slicing uniformly without any issue.
- Rotation of Trays
If your food dehydrator needs rotation in between the process of drying then, you must do that properly so that food does not get over dried. You should be attentive at the time of drying process. But if your dryer has temperature control feature, then you are safe from the over drying issue.
Is There Any Way to Supplement Any Vitamin Which Gets Lost in Drying Process?
Yes, of course, you can increase the content of Vitamin C in the dried food through the powdered citric acid, like Emergen-C. You can also use the lemon, and any other citrus fruits, Chili peppers, parsley and red bell pepper which are the few highest food sources of vitamin C. The dried spices like peppers (chili powder, paprika, and cayenne) and garlic can also work as a supplement.
Does the Dehydrated Food Lose the Fiber Content after Drying Process?
Well! Lots of people have a misconception in their mind that the dried vegetables and fruits do not have fiber which is false. When you dehydrate any food, the water content of the food gets reduced and not the fiber. In fact, in comparison to the raw food, the dried food has more fiber.
There are so many health professionals in the world who recommend their patients to consume dried food in case of constipation as such food has more fiber in it than the raw food. Thus, if you are concentrating on losing weight, then you can eat dried food without any stress of putting weight.
