The Verival fact check: freeze-dried berries

#1 What does “freeze-dried” mean?

Freeze-drying is a gentle method of drying berries. Freshly picked berries are deep-frozen, then placed in a vacuum chamber to draw out the water.


#2 How does that work exactly?

A special quality of water is that in a vacuum it transforms directly from a solid, frozen state into a gaseous state in a process of instant sublimation. The intermediate liquid stage is bypassed completely, the advantage being that vitamins, nutrients and colour are retained rather than being washed out. As a result, freeze-dried berries not only keep for a long time, but stay crunchy and retain virtually all their original vitamin and mineral content. When they come into contact with liquid, such as the milk you put on your muesli, the dried berries soak it up and take on a similar shape to fresh berries.


#3 How are berries usually dried?

Most other drying processes use heat to dehydrate the berries – but this also destroys the lion’s share of the vitamins. Also, since some residual moisture remains, sugar is often added to prolong the shelf life.  Freeze-dried berries, on the other hand, are full of flavour and require no added sugar – which makes them just perfect for our mueslis!


#4 What kind of berries do we freeze-dry?

We freeze-dry the following berries for our mueslis: sour cherries, sweet cherries, strawberries, raspberries, blackberries, blueberries, redcurrants and blackcurrants. You’ll find oodles of delicious freeze-dried berries in our Crunchy Muesli with Berries and our Heritage Grains Muesli with Berries, as well as in our Blackberry Porridge.
