Extracting these oils from plants is a delicate process that requires careful selection of methods based on the plant material and desired oil yield. Here, we explore the various extraction methods used in the industry:

Steam Distillation
This is the most common method for extracting essential oils. It involves passing steam through plant material, which causes the volatile compounds to evaporate. The steam carries these compounds, and the mixture is then condensed back into a liquid form. The resulting condensate separates into two layers: a water layer and an oil layer, from which the essential oil is collected.

Cold Pressing Technique
Also known as expression, this method is used primarily for citrus fruits. The outer peels of the fruits are pressed mechanically to release the oil. Cold pressing is preferred for citrus oils because it preserves the delicate aromatic compounds that can be destroyed by heat.

Solvent Extraction Method
This technique is used for extracting oils from plant materials that are difficult to process with steam or cold pressing. A solvent, such as hexane or ethanol, is used to dissolve the essential oil. Afterward, the solvent is evaporated or otherwise removed, leaving behind the concentrated essential oil.

Enfleurage
A less common method, enfleurage involves spreading plant material on a glass or metal surface coated with a layer of fat. The volatile compounds from the plant are absorbed by the fat. The fat is then processed to extract the essential oil.

Hydrodiffusion and Hydrodistillation
These are variations of steam distillation, where the plant material is submerged in water, and steam is passed through it. The process allows for a more controlled extraction, particularly for heat-sensitive plant materials.

CO2 Extraction
Also known as supercritical fluid extraction, this method uses carbon dioxide in a supercritical state to extract the essential oil. The CO2 is pressurized and heated to a point where it has the properties of both a liquid and a gas, allowing it to efficiently extract the oil.
