The invention relates to a method for obtaining etheric oils and/or constituents of etheric oils from the peel of citrus fruit and/or herbs that have a high residual moisture content comprising the steps a) extraction of the moist extraction material with an extraction agent mixture comprising at least one polar and at least one non-polar solvent for obtaining a miscella, wherein the extraction material is selected from citrus fruit peel and/or residues from the juice production from citrus fruits and/or herbs, wherein the extraction material has a residual moisture content of 5 to 95% by mass, measured on the total mass of the extraction material, wherein the extraction agent mixture contains at least one non-polar solvent in a proportion of 45 to 95% by volume, measured on the total volume of the extraction agent mixture, wherein the extraction agent mixture has a temperature above ambient temperature but below the boiling point of the lowest boiling-point solvent or of the lowest boiling-point azeotrope of the extraction agent mixture; b) separating the miscella from the extraction material; c) distillative separation of the miscella or distillative separation of the extraction agent mixture from the etheric oil and/or the constituents of the etheric oils.

An apparatus for extracting an oil from plant material includes an extraction chamber for plant material. The plant material is exposed to a heated gas stream with a temperature sufficient to volatilize on oil from the plant material. The gas stream is rapidly cooled to liquefy the oil into entrained droplets. The oil is collected with a collection solvent.

The present invention relates to a method for producing articles impregnated with at least one plant substance from at least one plant, characterized in that it comprises the following steps: a) Extraction and/or pressing of at least one plant (V1), or at least one part of said plant, producing a liquid plant extract (E1)) and a solid fibrous residue (R1), then b) Separation of said plant extract (E1) from said fibrous residue (R1), and c) Destructuring of said fibrous residue (R1), d) Production of a fibrous web or of an article made from the fibrous residue (R1) obtained in step c), and e) Impregnation of said fibrous residue (R1) with (i) at least said plant extract (E1), which is optionally concentrated, purified, flavored and/or fragranced, with (ii) at least one water-soluble or liposoluble plant substance isolated from said plant extract (E1), with (iii) at least one composition comprising at least one optionally concentrated, purified, flavored and/or fragranced water-soluble or liposoluble substance of said plant extract (E1), or with (iv) at least one plant extract (E2) or at least one composition comprising at least one optionally concentrated, purified, flavored and/or fragranced water-soluble or liposoluble substance of said plant extract (E2), resulting from an extraction or pressing of a plant (V2) different from said plant (V1).

Various aspects of this patent document relate to a method to extract an oil from a plant material using an apparatus by first exposing the plant material to a heated gas stream at a temperature sufficient to volatilize the oil from the plant material, and then rapidly cooling the gas stream to liquefy the oil.

Described herein are essential oils, extracts, apparatus and methods for the extraction of the essential oils and extracts from plant biomass using microwaves.

The disclosure relates to a method for extraction of plant essential oils from plant material using a water/water miscible extraction solvent or a water/hydrophobic extraction medium/water mixture as an extraction mixture.

Non-allergenic natural nut essential oil are derived from natural nut materials having 100 ppb or less protein such as nut butters by steam distillation or solvent extraction. The essential nut oils are preferably dissolved in a liquid edible carrier for use as nut flavor ingredients for food products. The food products flavored with such low protein essential nut oils are hypo allergenic. Methods of preparing the nut essential oils as well as methods of preparing nut flavored food products are disclosed.

An antibacterial essential oil includes 100 parts by weight of a Juniperus chinensis extract, 30 to 70 parts by weight of an Aquilaria agallocha extract, 30 to 70 parts by weight of camellia oil, and 10 to 40 parts by weight of a Dendropanax morbifera extract. Additionally, the antibacterial essential oil includes 10 to 40 parts by weight of a Portulaca oleracea extract, and 10 to 40 parts by weight of a Houttuynia cordata extract, 10 to 40 parts by weight of a Salicornia herbacea extract, and 10 to 40 parts by weight of a licorice extract. Further, the antibacterial essential oil includes 10 to 40 parts by weight of an Arctium lappa tea extract, 10 to 40 parts by weight of a jujube extract, 10 to 40 parts by weight of a Paeonia japonica extract, and 10 to 40 parts by weight of a Chamaecyparis obtuse extract.

Provided is a multi-functional apparatus that is able to isolate and collect organic compounds from plant material by way of steam distillation, organic solvent extraction, and oven purging and drying. The multi-functional apparatus is capable of being fitted with a variety of interchangeable condensers so as to accommodate the desired process. Among the organic compounds capable of being isolated and collected by way of the multi-functional apparatus are essential oils. Also provided is a botanical distillation and extraction apparatus which includes a main boiling chamber which is affixed with a selectively sealable cap. The selectively sealable cap is capable of being fitted with a variety of interchangeable condensers. The apparatus also includes a basket for holding plant matter that is attached to the boiling tank, a heating system, an optional vacuum system, and two distinctly unique condensers which may be interchangeably attached to the sealable cap according to the desired process.
