- Solvent Extraction and Absolute Creation
Solvent extraction involves the use of volatile solvents, such as hexane or petroleum ether, to dissolve the fragrant oils from rose petals. This process yields a concrete, a waxy substance containing both the fragrant oils and other plant materials. The concrete is then further processed with alcohol to separate the fragrant oils, resulting in an absolute. Solvent extraction is particularly effective for extracting heat-sensitive compounds that might be damaged by distillation. However, trace amounts of solvent may remain in the final product, potentially affecting its purity and safety. For example, Rosa centifolia, known for its delicate fragrance, is often processed using solvent extraction to preserve its nuanced aromatic notes. The resulting absolute captures a more complete olfactory profile compared to steam distillation, but requires careful quality control to ensure minimal solvent residue.
- Steam Distillation and Rose Otto Production
Steam distillation involves passing steam through rose petals to volatilize the fragrant oils, which are then condensed and separated from the water. This process yields rose otto, a highly concentrated essential oil. Steam distillation is a relatively simple and cost-effective method, but it can alter the chemical composition of the fragrance due to the high temperatures involved. Certain delicate aromatic compounds may be lost or transformed during the distillation process. However, rose otto produced through steam distillation is highly prized for its intense and long-lasting fragrance. Rosa damascena, known for its robust fragrance, is commonly processed using steam distillation to produce rose otto, which is widely used in traditional perfumery.
