How is essential oil extracted

Essential oils are extracted by distillation and pressing from flowers, stems, leaves, roots, bark, fruits, seeds, resins, etc. Because of their small molecular diameter, essential oils are easily absorbed by the body and can quickly penetrate through the body's organs, flushing out excess ingredients in just a few minutes. And the fragrance of plant itself, also stimulate directly the secrete of pituitary gland, ferment and hormone secrete, balance the function inside body, have the effect that hairdressing protects skin.

Evaporation is one of the earliest methods to extract aromatic essential oils from the plant world. With the evolution of different ages, the distillation apparatus of essential oils has significantly improved a lot. This is a very convenient method of refining by boiling the material with water or by using steam. Distillation has become the most widely used extraction method for essential oils.

The fresh or dry processing plant material into the steam heat furnace, heating from below into steam, came out of the plant essential oil evaporation, makes it contains essential oil vapor state, again through the catheter to collect after cooling freezing box, water vapor will condense into liquid by cooling, then according to the proportion of water and oil, the differences between the density and separation of essential oils, The remaining liquid is collected by a collector. In these liquids, more or less there are some essential oil components dissolved in it, which is called pure dew.

Geranium, Lavender, Roman Chamomile, and Eucalyptus in the aromatic essential oils are all extracted by this method.

Liposuction method is south of France south south Si (Grasse) the oldest kind of method that extracts fragrant essential oil, essential oil refines because place expend manpower and time very much, reason also is the most expensive refining method.

The principle is to extract aromatic essential oil by the physical properties of oil adsorbent. The fats used in the extraction of essential oils are specially treated to prevent them from spoiling and becoming odorous. Absorbing method is the use of cold fat, generally selected fat is containing lard and butter components.

Methods:

Basin, in the bottom of a wooden frame and glass basin, oil refining in pelvic floor coated with a layer of fat lukewarm, but the glass bowl around the place, to the edge of the left side is not coated with grease (this allows the saturated fat absorbed aromatic essence expansion has excess position with), and then spread a layer of freshly picked fresh petals in a place with grease. The bottom of a number of glass POTS are coated with grease and put the petals, and then the glass POTS are stacked one after another like tiles, so that the petals will be in the upper and lower layers of glass with grease, and the grease will absorb the essence of the petals. Allow the petals to remain in the oil layer for about 16-72 hours (depending on the flower species, usually daily), then replace another batch of petals. Repeat this process until the oil layer is completely saturated, which is indicated when the oil layer expands to the edges of the glass.

The process, which usually takes three months, is finished with alcohol and stirred by a machine, leaving behind the aromatic essential oils when the alcohol evaporates.

Jasmine, Rose, Neroil, etc. in the aromatic essential oils are all refined by this method.
