Essential oil is through the different way of extraction of extracted from plants, the extraction methods of oil separation method, solvent extraction, CO2 extraction method, water extraction method, etc.

- solvent extraction method On the market generally labeled 'absolute & # 39; Essential oil, it is to plant in petroleum ether or yourself. 。 。












essence is through the different way of extraction of extracted from plants, the extraction methods of oil separation method, solvent extraction, CO2 extraction method, water extraction method, etc.

- solvent extraction method On the market generally labeled 'absolute & # 39; Essential oil, it is to plant leaching in petroleum ether or hexane and volatile solvent, to transfer the aroma composition, after solvent evaporation, leaves the plant wax block ( 混凝土) , in alcohol solvent dissolved it in again, after being solvent evaporation, the refined into oil.
oil separation - use oil extraction of essential oil is one of the most ancient way, it has been widely used in the perfume industry, to capture the fragrance of flowers, such as jasmine. The smell of essential oil is absorbed by oil, the plant in the glass bottle with vegetable oil and exposure in the sun in a few weeks. The smell of plants were filtered out, add more herbs. Another way is to spread a layer on the thin lard flowers, flowers are required to cover up every day until the desired concentration. Finally, add alcohol to is as soon as the alcohol evaporates to isolate essential oil. GRASSE in the south of France is the only region in using this method. The oil price is very high, so the emblem on 'ENFLEURAGEABSOLUTE & # 39; 。
- CO2 extraction method The whole process under low temperature, so there is no heating effect. Solvent extraction process time needed for short, between the essence and doesn't have a chemical reaction. Comparison, the steam distillation need 1 to 48 hours, and there will always be essential oil residue remaining. Solvent in the process of lifting pressure was removed, the whole process is conducted in a closed room. CO2 extraction is in very high pressure state dissolved the essential oils from plants. When pressure to a degree, dissolution of essential oil in mist shape, then the collection. Because of its large and expensive equipment, this method is only used for precious essential oils. Its products will be labeled CO2.
hydraulic extraction - it is derived by steam distillation. Vapor penetration, down from plants to produce and its advantages for the steam quantity is low and the time is � � �, so can increase oil production. And the fragrance of essential oil from the good and the color.
