Different methods of essential oil extraction

You have recently been introduced to essential oils and are seeking to find out more about their extraction process. Extraction is employed to get the active botanical components of a plant that functions as its vital force. Before you buy oil extraction kits in the USA, make sure to find out about its extraction methods.

Essential oils are natural extracts from different parts of a plant. It includes leaves, flowers, twigs, seeds, peels of fruit, roots, bark. If you’re wondering how essential oils are extracted during a laboratory, here is what you would like to understand.

Essential oil extraction methods

Essential oils are extracted by steam distillation or expression.

Steam distillation

Steam distillation is that the hottest extraction method wont to obtain essential oils. It is because the botanicals are placed under pressurized steam. In addition, the recent steam forces aromatic compounds to escape the material while evaporating into the steam.

It is hot enough to let the oils without damaging the material. Next, the steam with oil particles passes through a cooling system to urge condensed into a liquid that contains oil and water. Since the oil is lighter than water, it’ll float to the highest, getting separated from the water.


This method of extraction is employed to get essential oils from the rinds of citrus fruits. This process involves soaking the peels of the fruits in warm water. Then, the oil is forced from the fabric using high mechanical pressure.

Solvent extraction

This technique uses solvents like ethanol to isolate volatile oil particles from the material. Solvent extraction is a perfect choice for plant materials that have low amounts of oil. A finer fragrance is produced during this method. The non-volatile material is additionally extracted using this method and sometimes removed through this.

Once the material is treated with the solvent, a waxy hydrocarbon is produced, called concrete. Next, the concrete is mixed with alcohol to let the oil particles release.

CO2 extraction

Essential oils also can be derived from superficial CO2 extraction. This method produces higher quality oils that are unadulterated even after undergoing high heat and pressure. Therefore, the oil particles obtained from this method are undamaged by heat.

CO2 extracts are thicker than their counterparts and provide off more of the aroma. In addition, they’re believed to possess more plan components than the quantity obtained from the same plant through steam distillation.

The process involves transforming CO2 gas into liquid by using pressure. Then it’s pumped into a chamber with the material. Due to the liquid properties of CO2, it functions as a solvent. It pulls the oil and other substances from the material. The oil content then gets dissolved into the liquid gas. Then, the CO2 is brought back to natural pressure to evaporate into the air as a gas form.

It’s essential to understand the oil extraction methods before you invest your money in oil extraction kits. Now that you have a good understanding of the methods, Viking lab will help you to make the right decision.
