Extraction Method:

Steam Distillation:

Steam distillation is separation process, in which oils are extracted from different parts of a plant, which are sensitive to high temperatures. This method can be applied to substances that are to be purified. In this purification process, a substance is purified through heating something with steam. In most cases, this process is applied for extracting essential oils from their combined natural sources. The principle on which this process is based on states that the insoluble objects when blended can decrease the boiling point of each other.

Co2 Extraction:

Carbon Dioxide (Co2) extraction process is another process for the extraction of plant's essence and essential oils. The carbon dioxide turns into liquid form when a specified pressure is applied to it. This is a static and safe liquid solvent. This method produces essential oils having several valued added benefits of preventing the thermal degradation accorded with distillation at atmospheric pressure. This extraction process works well when best in quality herbal extracts have to be produced for flavoring and herbal medicine industries.

Hydro Distillation:

Another extraction method is Hydro distillation, a perfect alternative to steam distillation process. This traditional method of extraction involves a hydro distillater, condensing apparatus, receiving flask and flowers or wood from which essence or essential oils are to be extracted. The plant material or wood is soaked in the water. When this container is heated, the produced steam and oil vapor are made denser and more concise in the condensing apparatus. There is a opening in the condensing apparatus, from where the excessive water dispenses out. The liquefied vapors or distillate are collected in the receiving flask.

Solvent Extraction:

Solvent extraction method, also known as liquid-liquid extraction, involves separation of compounds on the basis of their relative solubilities in two completely different non-miscible liquids, like water and organic solvents. Basically in this method, a solute is transferred from a liquid phase (feed solution) to another (solvent). The solvent that contains the solute is called extract and while that feed solution that doesn't have the solute is called raffinate.

Cold Pressed Extraction:

Cold pressed extraction, also called scarification method is another essential oils extraction process, which aromatic particles of plants and trees by infusing them into other substances. It is most used extraction method, when oils are to be extracted from seeds. The seeds are filtered, milled, pressed, filtered, and decantationed. This process results in 100% pure and natural oil retaining all its properties.
