Claims49
A method,
- wherein the method obtains an extract from plant biomass,
- wherein the extract is an essential oil,
- wherein the method comprises the steps of:
- a. obtaining the plant biomass;
- b. placing the plant biomass onto a conveyor belt, having a length, and introducing the plant biomass into a vessel having length, via the conveyor belt,
- wherein the plant biomass is introduced into the vessel by moving the conveyer belt at a first velocity, and
- wherein the plant biomass is introduced into the vessel at a rate;
- c. subjecting the plant biomass to microwave energy, of a first intensity, for a time sufficient to heat the biomass to a temperature to vaporize water within the biomass, thereby producing a distillate;
- and
- d. collecting the distillate.
An essential oil extracted from at least one plant of the Jasminium species, wherein the essential oil comprises at least 7% w/w (z)-jasmone.
An essential oil extracted from Piper nigrum, wherein the essential oil comprises at least 7% w/w sabinine.
An essential oil extracted from ginger root, wherein the essential oil comprises at least 13% w/w eucalyptol.
An extract from pears, wherein the extract comprises at least 0.1% w/w hexyl acetate.
An extract from roasted coffee beans, wherein the extract comprises at least 2% w/w coffee furanone.
