Lesson 06: Food Dehydration and Concentration

Difference Between Drying/ Dehydration and Concentration

Drying refers to the removal of relatively low amounts of water from a material as vapour by passing hot air while concentration/ evaporation refers to removal of relatively large amount of water as vapour at its boiling temperature. Concentration is not as effective as drying.

Foods are concentrated or dehydrated for the same purpose. Concentration is applicable in case of liquid foods only.
