Rapid, Solvent-Free Microwave Extraction (SFME) of Essential Oil
Analysis of essential oils
The analytical procedure for essential oils or aromas from plants or spices comprises two steps:
While the analysis step is complete after 15 to 30 minutes, the extraction step of essential oils represents 70 percent of the total processing time.
The NEOS System
The NEOS system is based on the Solvent-Free Microwave Extraction (SFME) technology for rapid extraction of essential oils from aromatic herbs, spices and dry seeds.
These novel processes can produce essential oil in concentrate form, free from any residual solvents, contaminants, or artifacts.
The NEOS system is the result of the partnership between Milestone and the "Laboratory of Chemistry of Natural Substances and Food Sciences” of the Université de la Réunion (France), which lead to the grant of the European patents 1439218, 1618798 and 1629725.
SFME is not a conventional microwave extraction process which utilizes polar and non-polar solvents nor a modified hydro-distillation method.
