The present invention provides a method for removing antinutrients from turmeric spice. The antinutrient such as oxalic acid is removed by using the method of present invention and thus the toxicity associated with it is also eliminated. The method includes preparing the turmeric powder and repetitively extracting the turmeric powder with inorganic acid. The turmeric powder is stirred in a pre-defined volume and pre-determined concentration of the inorganic acid for pre-defined time with constant agitation at pre-determined temperature to obtain a turmeric paste. The turmeric paste is then washed with water and dried to obtain the purified turmeric powder.

The present invention relates to a method for extracting collagen from a liposuction effluent, wherein collagen is extracted by treating a collagen-containing liposuction effluent in the presence of a supercritical fluid. According to the present invention, conventionally discarded collagen in a liposuction effluent can be extracted at high purity, and the extracted high purity collagen can be widely used in medical, pharmaceutical, and cosmetic products.

A system is provided that includes a solvent source; a canister adapted to contain plant material and positioned downstream of the solvent source; an extract container positioned for receiving and collecting at least a portion of an extract solution from at least the canister, the extract container further positioned to separate at least a portion of the solvent from at least the portion of the extract solution, thereby providing a recycled solvent; a solvent collection line for directing the recycled solvent; and a coolant line positioned for directing coolant that is thermally coupled to at least a portion of the solvent collection line for cooling the recycled solvent that is flowing through the solvent collection line.

A process for producing an aroma-laden gas (10) comprises the following steps: a) providing a liquid phase (5), which contains a solvent and one or several aromatic substances (1, 2, 3); b) guiding through a solid phase extraction column (3) of the liquid phase provided in step (a) by obtaining the solid phase (35) laden with one or several aromatic substances; separating one or several aromatic substances from the laden solid phase by means of at least one gas (2) in a liquid and/or supercritical state; and optionally d) collecting the gas (10), which is laden with one or several aromatic substances (1, 2, 3).

A method for separating and recovering compounds from biomass is provided. In the method, an aqueous extraction fluid in essentially gaseous phase, such as steam, is propagated through a reaction area containing biomass feedstock. When extraction fluid advances through the biomass feedstock, in predetermined reaction conditions, a target compound separates from the essentially solid feedstock matter and travels, with the extraction fluid, towards the end of the reaction area, in where the target compound is recovered in the form of an essentially liquid medium. The method is beneficial for extracting long-chain hemicelluloses from cellulose-containing feedstocks.

Disclosed is a natural compound sweetener, comprising mogroside V, rebaudioside A, natural tea theanine and dietary fibre. The method for preparing the sweetener comprises the steps of: (1) dissolution, filtration, concentration and sterilization: dissolving the mogroside V, rebaudioside A, natural tea theanine and dietary fibre in water, filtering, concentrating in a vacuum, and sterilizing to obtain a sterilized solution; and (2) paste-collection, drying and granulation: carrying out paste-collection on the sterilized solution obtained in the step (1), vacuum drying the collected liquid paste, and drying and then granulating the dry powder to obtain the sweetener.

Provided is a process including: extracting a first plurality of active ingredients of a first plant material using a first extraction solvent; extracting a second plurality of active ingredients of a second plant material using a second extraction solvent; transferring the first plurality of active ingredients from the first extractant solution filtrate to a carrier solvent; encapsulating the first plurality of active ingredients in one or more nanoparticles; dispersing the one or more nanoparticles in an aqueous suspension; and adding the second eluant from the second plant material to the aqueous suspension.

A method for extracting and isolating terpenes and aromatic compounds from Cannabis plant material by the steps of grinding the cannabis plant material to obtain a ground cannabis, performing a CO2 supercritical extraction upon a first portion of the ground cannabis, wherein said supercritical extraction is performed at temperature below freezing, between −30 to 0 centigrade, for a period of 3 to 5 hours, at between 1000-1300 psi, performing a steam distillation upon a second portion of the ground cannabis, performing a butane extraction upon a third portion of the ground cannabis, wherein the butane extraction is performed at a temperature between −30 to 0 centigrade, performing an alcohol extraction upon a fourth portion of the ground cannabis, wherein the alcohol extraction is performed at a temperature between −30 to 0 centigrade, performing a maceration upon a fifth portion of the ground cannabis, wherein the maceration is performed with coconut oil at a temperature of between 40-70 centigrade, combining at least a portion of each of the resultant extracts from the CO2 supercritical extraction step, the steam distillation step, the butane extraction step, the alcohol extraction step and the maceration step to create a combined extract, and then fractionally distilling the combined extract to separate terpenes and other aromatic compounds from the combined extract.

Disclosed herein are improved methods and devices for recycling lithium cathodes from batteries.
