Solvent free microwave extraction (SFME) has been demonstrated to be feasible in extraction of essential oils from botanical materials. The benefits are no need for any solvent aside from the water naturally in the botanical material and a significant reduction in environmental impact for large scale production processes. However, the...
Steam distillation has been the common method of extraction of essential oils from plants for more than a century. The use of microwave energy has been suggested as an alternative distillation method that would: reduce water usage, dependence on non-renewable energy sources, and the carbon footprint. A byproduct of this...
Two field experiments were established during the spring of
1970 in an effort to characterize the effects of nitrogen fertilizer and
plant maturity on the yield, composition and quality of peppermint
(Mentha piperitta var. Mitcham) oil. These experiments were located
in central Oregon, near Madras, and in the Willamette Valley,...

The increase of diesel fuels and natural gas has increased the energy cost of the mint
oil extraction industry in the Willamette Valley. In this study the energy evaluation of
a distillation facility in Oregon is considered. Solvent free microwave extraction of
peppermint oil is introduced as a new technique...
