Essential Oils are highly concentrated plant extracts obtained through
steam distillation of flowers, seeds, berries, roots and barks or citrus
rind expression.
Steam distillation is the most common extraction method of essential
oils in which a still is charged with plant material to be processed.
Steam is introduced at the base of the still and the plants volatile elements
evaporate with the steam. A condensation process turns this vapour-mix into
a liquid form of water and oil which floats on the top of the water and
is separated off.
Cold pressing, also known as expression, is used exclusively for citrus
oils. This is a very mild and gentle pressing treatment in which the outer
layer of the peel is ruptured and the oil is then pressed out. |
