Freeze-dried vs dehydrated fruit
Both remove water from fruit, but in different ways. Dehydrated fruit is usually dried with warm or hot air, so its water evaporates over time. Freeze-dried fruit is frozen first and dried under reduced pressure, so its ice turns directly into vapour. That is why the two usually differ in texture, shape and how much heat the fruit goes through.
- Freeze-dried
- Frozen, then a vacuum. Ice turns to vapour. Usually light, porous and crisp.
- Dehydrated
- Warm or hot air. Water evaporates. Usually denser and chewier.
- Choosing
- Mostly a question of texture. Then read the ingredient list.

What “dehydrated” means here
Strictly, freeze-drying is also a way of dehydrating food: it removes water. In everyday use, though, “dehydrated fruit” means fruit dried the conventional way, usually with heated air in a dehydrator or oven, sometimes in the sun.
This guide compares freeze-drying with conventional hot-air drying, which is also the comparison most published studies make.
Side by side
The comparison
| Freeze-dried fruit | Dehydrated fruit | |
|---|---|---|
| Process | Frozen first, then dried in a sealed vacuum chamber with gentle, controlled heat. | Dried with heated air, usually in a dehydrator or oven, over an extended time. |
| How the water leaves | Sublimation: ice turns directly into vapour. Water still bound to the solids is removed last, by desorption. | Evaporation: liquid water turns into vapour. |
| Heat | Low product temperatures, kept below the point where the drying structure would collapse. | Longer exposure to heated air. |
| Air during drying | Largely kept out by the vacuum. | Dried in air. |
| Shape | Usually keeps much of its original shape, with less shrinkage. | Shrinkage and collapse are common. |
| Texture | Typically light, porous and crisp. Varies by fruit and process. | Typically dense or chewy. |
| Colour and flavour | Generally well kept. | Heat can change colour and appearance. |
| With moisture | Takes up water quickly through its open pores, including moisture from the air, which softens it. | Takes up water less readily. |
| Time, energy and cost | Slow, energy-intensive and comparatively expensive. | Faster and more economical. |
| What the method adds | Nothing. Check the ingredient list. | Nothing. Check the ingredient list. |

Texture
Why one crunches and the other chews
In freeze-drying, the water leaves while the fruit is still frozen and rigid, so its solids stay largely in place. The spaces the ice filled become pores, and that dry, porous network is brittle: it breaks cleanly when you bite it.
In hot-air drying, the fruit dries while warm. Shrinkage and collapse are common, and the result is usually a denser, chewier piece.
How sublimation works, stage by stage, is in the companion guide.
Choose
Which one should you choose?
Start with the texture you want.
- Crisp and light
- Freeze-dried. It breaks with a snap, and it adds crunch to yogurt, oatmeal or ice cream.
- Soft and chewy
- Dehydrated. It is denser and chewier.
- Then, the label
- Whichever you choose, the ingredient list tells you whether the pouch holds fruit alone or fruit with anything added.
Both kinds keep best sealed. Freeze-dried fruit in particular softens once it takes up moisture from the air.
ASTROVE
Which one is ASTROVE?
ASTROVE is freeze-dried.
ASTROVE is freeze-dried tropical fruit, one kind in each pouch. Preparation varies by fruit: Mango, Java Plum, Pink Guava and Papaya are puréed and formed into pieces before freeze-drying; Pineapple is peeled and cut into pieces.
- Alphonso MangoOne ingredient: mango.
- Java PlumOne ingredient: Java Plum.
- PineappleOne ingredient: pineapple.
- Pink GuavaOne ingredient: pink guava.
- PapayaOne ingredient: papaya.
ASTROVE is not on sale in Canada yet. Availability will be announced when it is confirmed.
