Orris butter

Because of its high content of myristic and other fatty acids, the steam distillate is a waxy mass that resembles a concrete and is sold under this name or as Beurre d lris (Orris butter). In addition, a neutral product, obtained after removal of the acids with alkali, is marketed under the name orris oil absolute or as orris oil 10-fold.

Orris rhizomes of both Italian and Moroccan origins are hydrodistilled in water (P) to provide an essential oil. Orris essential oils, which are solid at room temperature, are frequently misnamed concretes. They also go by the name of orris butter, which is explained by their butter-like texture. A subsequent purification step by alcohol extraction into an absolute eliminates the fatty acids from the essential oil (butter, concrete). 

G.i Iris Absolut/Ol E absolue/essence d iris The rhizomes (subterranean stems) of the - orris flower are the starting material for the most expensive - fragrance and - flavor raw material. After harvesting, the rhizomes have to be washed, decorticated and stored for three years fresh material is practically odorless. The material is then pulverized and steam-distilled with an extremely low yield (<0.1%). The resulting - essential oil solidifies in the receiver to a wax-like, cream-colored mass, which explains why this product is frequently termed orris concrete or orris butter. This phenomenon is due to the high content (85-90%) of - myristic acid, which is removed by alkaline washing of the orris oil in ether solution to yield orris absolute.
