Essential Oil Extraction Methods



Machine Abrasion





Machine Abrasion is very much same as coldpressed expression method and is mainly used in extraction of citrus essential oils.

In machine abrasion, a machine strips off the outer peel of the botanical material, which is then removed by running water and left over is then fed into a centrifugal separator.


The centrifugal separation is done extremely fast. But, it should be noted that due to the fact that the essential oil is combined with other cell content for some time, some alteration could occur in the oil due to enzymatic action.
