Rose Essential Oil very expensive oil extracted from rose petals. Rosa damascena, one of the major species used in production of Rose Oil. The steam-distilled oil is a pale yellow-green, oily with a very strong, aromatic perfume. At a low temperature, shiny, long crystals of stearoptene form in a thin layer on top of the oil. The principal constituents: Eugenol, famesol and other acids, geraniol (or citronellol), linalool, nerol, nonylic aldehyde, rhodinol and stearoptene.

Three Methods of extracting Rose Oil from Plant Material Steam Distillation: produces an oil called rose otto or attar of Roses. Solvent Extraction: results in an oil called Rose absolute Supercritical Carbon Dioxide Extraction: gives an oil called as absolute or CO2 extract

SOLVENT DISTILLATION OF ROSES  blossoming time is in early May the workers pick all the flowers into big baskets which are then taken to the distillery at the heart of the plantation.  They work quickly as the flowers lose moisture, needing to be sprayed occasionally with water

SOLVENT DISTILLATION OF ROSES

SOLVENT DISTILLATION OF ROSES The workers bring in the heavy baskets of 25 kg (55 lb) each – and spread the flowers on five trays layered inside each ‘pressure cooker’ ¬when the lid is closed; the solvent and water are added by opening a valve. 

SOLVENT DISTILLATION OF ROSES The operation is begun, and the temperature is checked – it will reach a maximum of 45 – 50°C (113 -122°F). The solvent and the water run continuously through the trays of flowers, impregnating them and taking with them the odoriferous molecules. These gather as a concrete, very stiff and waxy, at the bottom of the cylinder in a small bowl. Each set of trays is ‘cooked’ for about an hour, then the solvent-saturated flowers, now a dull grey, are discarded and replaced by fresh ones until the operation is complete and the bowls are full.
