At this particular temperature and strain, the ice crystals in the foods evaporate into drinking water vapor, bypassing water’s liquid kind, via a approach known as sublimation.

This method preserves the cell structure and dietary content of the food, ensuing in a solution that, when rehydrated, really carefully resembles the original meals.
The approach also stops the water from becoming reabsorbed by the meals and as a result decreases its fat drastically.

Rehydrating freeze-dried meals normally takes just a few minutes, just by including boiling h2o. Some foods, like several fruits and veggies, need to have no re-hydration just before taking in.

Dehydrated meals shrink in the course of processing as the dampness is eliminated. So the foods product itself is considerably more compact than its unique measurement.

The re-hydration time of dehydrated foodstuff will take a bit lengthier than freeze-dried, but it stills preferences like the first type of the foods. Some dehydrated meals contain additional substances to boost flavors or assist in preservation.
