Hydro-distillation is a different process. The raw materials are immersed in water, which is then heated to allow for the evaporation of the components which, once cooled, will form the essential oil. These units can be equipped with stirrers to increase suspension and accelerate the process, making them particularly well-suited for powdered ...

In steam distillation of essential oils, the temperature involved in the process changes the molecular composition of the essential oil. One excellent case in point is that of German (Blue) Chamomile ( Matricaria recutita ) where, during distillation, the matricin component of the oil changes to chamazulene upon exposure to high temperatures ...
