The present invention provides a powdered botanical extract preparation comprising an evenly distributed dispersion of a botanical extract in a methylsulfonylmethane matrix, processes for preparing the preparations, and dosage forms comprising the preparations.

A method of preparing paprika red pigment with low polycyclic aromatic hydrocarbons includes (1) drying, crushing and granulating mature peppers to obtain pepper particles; (2) extracting the pepper particles with a vegetable oil in a rotocel extractor to obtain a paprika red pigment solution; (3) extracting the paprika red pigment solution with an ethanol solution in a liquid-liquid extractor to remove spicy substances; (4) running the paprika red pigment solution through a low-pressure chromatography column to remove polycyclic aromatic hydrocarbons; and (5) concentrating the paprika red pigment solution to obtain the paprika red pigment with low polycyclic aromatic hydrocarbons.

A method for extracting bioactive compounds from plant materials using supercritical glycerin and at least one inert co-solvent that lowers the effective supercritical point of the supercritical glycerin to its boiling point, and the extracts obtained from the method.

This invention relates to the extraction of psychoactive compounds from organisms for use in medicine. Extraction is carried out with a strong acid or strong base to either promote or inhibit dephosphorylation. The extract in the slurry form is standardized with added excipient so that when it is dried the powdered composition has a specified total psychoactive alkaloid concentration, with a known ratio of phosphorylated to dephosphorylated psychoactive alkaloids.

A method of extracting at least one cannabinoid from a biomass comprises the following steps (i) contacting the biomass with a solvent formulation which comprises a C.sub.1-4 fluorinated hydrocarbon or a C.sub.1-4 hydrofluorocarbon ether, thereby to charge the solvent formulation with an extract from the biomass; and (ii) separating charged solvent formulation from the biomass.

Described herein are an extract from lettuce (Lactuca sativa), in particular of stalk lettuce (Lactuca sativa var. angustana), including 2-acetyl-1-pyrroline and, optionally, precursors of 2-acetyl-1-pyrroline as well as flavoring compositions including such an extract and a method for the preparation of such an extract. Also described herein are the use of such an extract as a taste or flavor ingredient in a consumer product and a method of enhancing, improving, modifying the taste or flavor of a consumer product by making use of such an extract.

A method of extracting one or more chemical extracts from a plant product includes mixing at least a first phytochemical-bearing part of a phytochemical plant product with an oil-bearing plant product, producing an oil mixture from the first phytochemical-bearing part and the oil-bearing plant product using a press device, and extracting at least a chemical extract from the oil mixture.

Green bodies are safely, economically and efficiently debound in a dual quartz reactor by subjecting them to a steady laminar upward flow of freshly distilled solvent so that the concentration difference of soluble binder at the green body/solvent interface is at all times maximized for optimum binder extraction as per Fick's laws of diffusion. Binder extraction rate is monitored by inline spectrophotometry of the reactor overflow. Following solvent extraction, the residual insoluble binder is thermally extracted without the need to transfer the green bodies to a different vessel.

System and methods for recycling a material comprising a polymer in an expanded state is disclosed. The system can include a shredder, a heating chamber operatively connected to the shredder, a condenser operatively connected to the heating chamber, a solvent tank operatively connected to the condenser, and a circulation unit operatively connected to the solvent tank and the heating chamber.

The present invention relates to a method of extracting a pigment from microalgae.
