Why is clove oil extraction by steam distillation?
Steam distillation is used because if the cloves were heated directly, the oil and cloves might be damaged, instead it is heated by the steam which is gentler. The safety tube must be below the surface of the water in the boiling flask. Clove oil is non-polar, therefore is insoluble in water.
How oil is extracted from cloves?
During hydro distillation method, powdered sample (100 g dried and ground clove buds) is soaked into water. To carry out hydro-distillation, dried clove sample is taken into 500 mL volumetric flask and subjected to hydro-distillation for 4–6 hours.
Which essential oils are steam distilled?

How is clove oil distilled?
Eugenol concentration in clove oil is as high as 90%. Most essential oils are extracted by direct or indirect steam distillation. Steam distillation is a co-distillation technique that uses live steam to separate components of a mixture.
What does steam distillation do?
Steam distillation is a separation technique that harnesses the low boiling point property of immiscible mixtures. It is predominately used to separate temperature-sensitive organic molecules from a non-volatile contaminant. The organic molecule must be immiscible in water.
What is the principle of steam distillation?
The principle behind the steam distillation process is that when the heating of a mixture of two or more immiscible liquids takes place, the vapour pressure exerted by the system increases. This is because it now becomes the sum of the vapour pressures of all of the components of the mixture combined together.
How does steam distillation work for essential oils?
Steam Distillation is the most popular method used to extract and isolate essential oils from plants for use in natural products. Through an inlet, steam is injected through the plant material containing the desired oils, releasing the plant’s aromatic molecules and turning them into vapor.
How do you extract essential oils using steam distillation?
STEAM DISTILLATION
- A large container called a Still, which is usually made of stainless steel, containing the plant material has steam added to it.
- Through an inlet, steam is injected through the plant material containing the desired oils, releasing the plant’s aromatic molecules and turning them into vapor.
How does steam distillation extraction essential oils?
Steam distillation is the most popular method to extract essential oils. During this process the botanicals are placed into a still and pressurized steam is forced through the plant material–imagine using a steaming basket on your stove. The hot steam forces open pockets of aromatic compounds.
How do you extract clove oil from cloves?
Method
- Using a mortar and pestle simply crush half a teaspoon of whole cloves with a tablespoon of olive oil.
- Add the rest of the olive oil and pour this into a small jar.
- Leave for a week then strain out the solids and pour the resulting homemade clove oil into a small sterilised bottle or jar.
Is steam distillation good for essential oils?
Steam distillation has been the traditional method to isolate volatiles from fragrant plant materials. Steam distillation and the related hydrodiffusion technique are used to isolate the essential oils from lavender or from rose petals. It is a suitable method if plenty of plant material is available.
