Microwave Green Extraction of Natural Products

FOR THE RAPID SOLVENT-FREE MICROWAVE EXTRACTION OF ESSENTIAL OILS The new Milestone’s ETHOS X dedicated to the Microwave Green Extraction of Natural Products takes advantage of the unique microwave selective heating mechanism: it is able to free essential oil, which is evaporated by the in-situ water of the plant material. The Fragrances confi guration is based on the solvent-free microwave extraction (SFME) technology for the rapid extraction of essential oils from aromatic herbs, spices and dry seeds. Microwave extraction is performed at atmospheric pressure and without any addition of solvent or water. High quality fragrances are obtained without residual solvents, contaminants and artifacts. The Flavors confi guration is based on the microwave hydro-diffusion and gravity technology (MHG), a new and green method of essential oils extracted from different kinds of aromatic plants. It allows the microwave extraction of natural flavoring substances and non-volatile compounds such as pigments, flavonoids and carotenoids. With both confi gurations, essential oils can be analyzed directly by GC-MS without any preliminary clean-up or solvent exchange steps.
