A system for processing essential oils includes a mixing tank, three winterization vessels, three respective filtering vessels, a fine filtering vessel, a holding tank, an evaporator, an essential oil reservoir, a solvent reservoir, and a solvent filtering vessel. The evaporator can include a heat exchanger configured to heat a plate down which a mixture including the oils flows, to evaporate other components of the mixture. Fluids can be advanced through the system using a pressurized inert gas.

The invention provides a method for extraction of at least one extract compound from a material, comprising: a. contacting carbon dioxide with the material to dissolve an amount of the at least one extract compound from the material into the carbon dioxide; b. contacting the carbon dioxide comprising the at least dissolved extract compound with a sorbent to sorb the at least one extract compound onto the sorbent and for regenerating the carbon dioxide; c. recirculating the regenerated carbon dioxide; and d. repeating said recirculating at a constant density of said carbon dioxide of between 100 and 1000 kg/m.sup.3, and repeating said recirculating for at least 10 cycles.

The present invention relates to the use of 3,3′-dimethoxy-4,4′-dihydroxystilbene as an odorous substance, in particular for developing a vanilla odor under the action of light. Furthermore, the invention relates to a composition which contain 3,3′-dimethoxy-4,4′-dihydroxystilbene and additionally a carrier, fragrance compositions and/or an odorant material which contain said compound and a process for imparting or modifying an odor of compositions by adding said compound to these compositions. The invention additionally relates to a process for obtaining 3,3′-dimethoxy-4,4′-dihydroxystilbene from lignin-containing compositions.

A system, machines and methods for extracting select moieties, flavonoids, and essential oils from plant material without co-extracting chlorophyll, lipids and other undesirable constituents from plants. Super-cooled extraction techniques are taught. Likewise, according to embodiments methods provides 100% grain ethyl alcohol extract with a concentration of chlorophyll that is below 1%.

A method for modifying the composition of essential oils to be used as such or as ingredients for flavour and fragrance formulations, the process using carbon dioxide and suitable solvents in combination with specific supports; Flavours and fragrances containing ingredients produced by the method and applications using the flavours and fragrances.

The invention relates to a method for obtaining value-determining contents, such as flavouring substances, vitamins, and polyphenols, from foods (13), having the following steps: a) providing a food (13), b) adding a plant oil (15) as an extractant, c) grinding the food (13) and the plant oil (15) into a mash (21), and d) separating the mash into an extraction phase, which is an oil phase (25), and a solid phase (29) as a raffinate phase. The food (13) and the plant oil (19) are ground very finely, said grinding process being defined in that the food (13) together with the plant oil (15) is ground until the oil phase (25) has an average particle size of less than 300 μm, preferably less than 100 μm, particularly preferably less than 20 μm.
