When steam distillation is used in the manufacture and extraction of essential oils, the botanical material is placed in a still and steam is forced over the material. The hot steam helps to release the aromatic molecules from the plant material since the steam forces open the pockets in which the oils are kept in the plant material.

Essential Oil Extraction Process – aromarain

CO2 EXTRACTIONPHYTONIC EXTRACTIONBUTANE EXTRACTIONENFLEURAGEMACERATIONCOLD-EXPRESSIONThe most recent method is that of the distinguished carbon dioxide extraction. It employs a much lower temperature than that of steam distillation. This process was to introduce oils that remain close to the way they reside in nature. This is primarily due to the inert nature of the solvent and lower pressures. There is some disagreement to this theory in that due to the acidic nature of CO2 one could argue it is disruptive to the chemistry of the resultant oil. Whereas terpenes are often man…

Antimicrobial Properties of Plant Essential Oils against

Although essential oils can be recovered using fermentation, extraction, or effleurage processes, commercial production is preferably achieved by the steam distillation process [1, 4, 110]. Likewise, the antimicrobial efficiency of essential oils depends on the type of microbes to be inhibited as well as the evaluation methods, including
