Freeze dried and dehydrated fruits are common snack foods. Although they are made in different ways, they retain most of the nutrients, smell and taste of fresh fruits. They also have a longer shelf life than fresh fruits and can be used in a variety of ways. In this article, we compare the common attributes of freeze dried vs dehydrated fruits from a consumer approach, hoping to help you make easier selection between the two.

How are Freeze Dried and Dehydrated Foods Produced?
We begin by a short description of the production process for freeze dried vs dehydrated fruits. Dehydration involves removing the moisture from food by exposing it to low heat, typically between 130°F and 170°F, for several hours. This process can be done using a dehydrator or an oven with low heat. The goal is to remove all of the water content from the food, which inhibits the growth of bacteria and other microorganisms that cause food spoilage.Â
Freeze drying includes several related steps. It involves freezing the food at extremely low temperatures (-40°F to -50°F) and then placing it in a vacuum chamber. The chamber is then heated slightly, causing the ice in the food to sublimate, or turn from a solid to a gas. This process removes all of the water content from the food while preserving its nutritional value, texture, and taste. Although we did not cover it in this article, the general method of freeze drying is very similar for most fruits and vegetables. But dehydrating may not work in the same way for fruits and vegetables.
Freeze Drying Preserves More Nutrition and Less Water
Freeze drying is often considered the superior method of food preservation when it comes to retaining nutritional value. This is because freeze drying removes almost all of the water content from the food without subjecting it to high temperatures that can break down nutrients. In fact, freeze drying can preserve up to 97% of a food’s nutritional content, including vitamins, minerals, and enzymes.
Dehydrating, on the other hand, can result in some loss of nutritional value due to the exposure to heat. However, the extent of the loss can vary depending on the specific food being dehydrated, the temperature at which it is dehydrated, and the length of the dehydration process.
Freeze Dried vs Dehydrated Veggies
Dehydration uses warm air or heat to remove 70% to 90% of the moisture from vegetables. Freeze drying uses really, really cold temperatures to freeze or trap the moisture inside vegetables, which is then removed by sublimation. These two methods yield different products. Table 1 summarizes the difference and table 2 shows advantages and disadvantages of freeze dried vs dehydrated vegetables.
It should be noted that most people may use other methods of drying as well, depending on market, personal preference and nutritional needs.
Taste Stays the Same in Freeze Drying and Dehydrating
The taste nearly stays the same in freeze dried vs dehydrated fruits. Both freeze drying and dehydrating can result in foods that retain their original taste and texture. This is because the processes do not involve adding any chemicals or preservatives that can alter the flavor or texture of the food. In fact, some people prefer the taste and texture of dehydrated or freeze-dried foods, such as fruits and vegetables, over fresh ones.
Freeze Dried Fruits Rehydrate Faster
Freeze dried fruits take less time to rehydrate compared to fresh or dried fruits. This is because the freeze drying process removes most of the moisture from the fruit, which makes it easier and faster to rehydrate.
On the other hand, dried fruits have a higher water content, which means that the water needs to penetrate the fruit and replace the existing moisture. This can take longer and may require soaking or cooking to fully rehydrate the fruit.
Dehydrated Fruits Have a Chewy Texture
Unlike the crispy texture of freeze dried fruits, dehydrated fruits generally have a chewy texture because the drying process removes most of the moisture that makes the fruits soft and juicy. As a result, the remaining fruit material becomes denser and more concentrated, which can give it a chewy or slightly tough texture.
What are Freeze Dried and Dehydrated Fruits Applications?
Freeze dried and dehydrated fruits have a wide range of applications. They are commonly used in the food industry to make snacks, breakfast cereals, and trail mixes. They are also used in the production of baby food, pet food, and emergency food supplies. Additionally, freeze-dried and dehydrated fruits are popular among outdoor enthusiasts and hikers who need lightweight, portable, and long-lasting food options.
In the home kitchen, freeze dried and dehydrated fruits can be used in a variety of ways. They can be rehydrated and used in recipes that normally call for fresh fruit, such as smoothies, baked goods, and sauces. They can also be eaten as a snack, added to breakfast cereals, or used as a topping for yogurt and ice cream.
However, there might be one area where we expect different applications for freeze dried vs dehydrated fruits. Freeze dried fruits have a crispy texture (compared to the chewy texture of dehydrated ones) and they readily turn into powder by rubbing, whereas dehydrated fruits may need grinding to form a powder. Additionally, there seem to be more creative ways to enjoy freeze-dried fruits in recipes than there are for dried ones.Â
How Long Freeze Dried and Dehydrated Foods Last
Both freeze-dried and dehydrated foods have a long shelf life compared to fresh foods. Dehydrated foods can last anywhere from six months to 10 years if stored properly in an airtight container in a cool, dry place. The shelf life can be affected by storage conditions and moisture content.
On the other hand, freeze-dried foods can last up to 25 years if stored in an airtight container in a cool, dry place. However, once the container is opened, the shelf life decreases to about 1 to 2 weeks, depending on the humidity and temperature of the storage location.
Freeze Dried vs Dehydrated Fruits: Which One to Choose
The choice between freeze dried vs dehydrated fruits depends on personal preference and the intended use. Both freeze-dried and dehydrated fruits are great options for preserving fruit for longer periods of time.
On the one hand, freeze-dried fruits tend to retain more of their original flavor, color, texture and nutrients, as they are dried at a lower temperature and have less exposure to oxygen. Also, freeze-dried fruits tend to rehydrate faster than dehydrated fruits, which can be an advantage in recipes where time is a factor.
On the other hand, freeze-dried fruits can be more expensive than dehydrated fruits, and dehydrated fruits can have a chewier texture that some people prefer.
