Hydro-Distillation of Oils From Aromatic Herbs

Steam distillation for extracting essential oils from plant materials is a very simple operation. In fact, it is so simple that, for a long time, no one thought the way that the steam liberates the oil was worth investigating. So, until recently, this was very poorly understood and distillers were unaware of much inefficiency and waste built into stills and their operating procedures.

The Essential Oil from Rosmarinus officinalis L.

The essential oil produced from the leaves of Rosmarinus officinalis L. is an important essential oil of Spain.

The following sections treat history, botany, essential oil production, physiochemical properties, chemical composition, olfactive properties and applications, and production and trade of the essential oil of Rosemary. The preparation of terpeneless essential oil of Rosemary will be mentioned.

Water-Soluble Fractions of the Essential Oils

Due to the different solubilities, various essential oil components are disproportionately postitioned into the aqueous phase and, hence, the variable polar components are either reduced or lost. Because of this phenomenon, relatively soluble minor components of the oil can escape completely resulting in an unbalanced odor and flavor profile when compared with that of the original plant. Therefore, the water soluble fraction is of importance to both the quantitative and qualitative outcome of the essential oil production.
