<p>A process is provided for separating essential oils from an essential oil-containing material. The process comprises the steps of subjecting the essential oil-containing material to steam distillation using a steam distillation vessel or extraction using an extraction vessel. This produces a mixture containing the essential oil and at least one hydrophilic phase. This mixture is then contacted with a hydrophobic adsorbent in an adsorption vessel. The hydrophilic phase leaving the adsorption vessel is recycled to the steam distillation vessel or extraction vessel. Finally, the essential oils are desorbed from the adsorbent.</p> |
