Freeze Dried vs. Dehydrated Foods
The Differences Between Freeze Dried vs. Dehydrated Foods
If you’re a newcomer to the freeze-dried snack craze, you may not know the difference between freeze-dried vs. dehydrated snacks. While freeze-dried snacks may sound similar to traditional dehydrated (or simply dried) snacks, there are a few key aspects in which the two differ in terms of texture and taste, among other ways.
Below, we’ve highlighted six of the main differences between freeze dried vs. dehydrated snacks.
The best way to understand the difference between freeze-dried vs. dehydrated snacks is by learning about the processes to make each of them.

Appearance & Texture
Because freeze drying removes nearly all moisture or water content from the food, it has a much crispier, airy texture than food that is simply dehydrated. Dehydrated fruit, for example, tends to be chewy and sweet because it still holds about a third of its original water content (some dried fruits such as bananas become hard and brittle). On the other hand, fruit that is freeze-dried contains little to no moisture content at all. This allows foods that are freeze-dried to have a crispy, crunchy texture. You’ll be surprised at how much lighter in weight freeze dried fruit is compared to dehydrated fruit.
- Taste Here’s the difference. Dehydrated foods can lose much of their flavor, mainly due to the heat drying processes used to remove the moisture. Freeze dried foods (including fruits!) keep most of their original flavor until they are ready to be enjoyed.
- Nutrition Freeze dried fruit retains nearly all of their original nutrients. This is because freeze-drying only removes the water content. Dehydrating can strip more nutritional content due to heating processes commonly used to evaporate moisture.
- Additives Dried snacks usually require a fair amount of preservatives to keep them fresh. Because freeze drying removes most of the moisture, there is no need to add in additives to preserve for long periods of time. This makes freeze-dried fruit a healthier option.
- Shelf-Life Because dehydrated foods contain about a third of their moisture, they have a much shorter shelf-life. The water trapped inside dehydrated foods can easily grow mold and bacteria. Conversely, freeze dried foods can last for years in the proper packaging at room temperature and retain its original flavor and crispiness!
