Abstract
The Effect of Seawater Used for Hydrodistillation on Essential Oil Yield and Composition of Oil-Bearing Rose (Rosa damascena Mill.)
Highlights
The oil-bearing rose (Rosa damascena Mill) has a pink flower with 30 petals with heavy rosy scent
A total of 23 essential oil constituents were detected by Gas Chromatography/Flame Ionization Detector (GC-FID)/MS analyses
Some of the essential oil constituents which are naturally not present or very little quantities in the rose flowers can be produced either enzymic splitting or chemical degradation, occurring during the distillation from the high molecular weight and nonvolatile compounds present in the plants
Summary
The oil-bearing rose (Rosa damascena Mill) has a pink flower with 30 petals with heavy rosy scent. Even with its high price in the world markets (over 10.000 €/kg with a value of 2017), rose oil is the most widely used essential oil in perfumery and cosmetics. The main industrial product from oil-bearing rose is rose oil, rose water, rose concrete and rose absolute, which are produced by water distillation and solvent extraction processes [1, 2, 3, 4]. Turkey and Bulgaria are the leading countries that they meet over 90 percent of the world rose oil, concrete and absolute production. Hydrodistillation with cohobation is widely used method for producing volatile oils from oil-bearing rose in the industrial process of hydrodistillation with retorts or stills [5]
