In accordance with the invention, it was found, surprisingly, that a polyunsaturated fatty acids (PUFAs)-comprising biomass with other feedstuff components can be extruded at a low energy input of 12-28 Wh/kg to give an extrudate with a very high oil load capacity.

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.

A method and system of and for extraction or removal of phytochemicals from plants, including those of the plant family Cannabaceae sensu stricto. More specifically, a method and system for extracting essential oils from plants, such as cannabis, without the use of a solvent.

A plant oil extraction system may include a reservoir tank, an agitator tank, a boiler tank, a condenser unit, and a vacuum chamber. The reservoir tank may hold a solvent to be used in the system process. The solvent may be deposited into the reservoir tank through a fill port. A pump may transfers the solvent from the reservoir tank to the agitator tank. The agitator tank may hold dry plant matter. The agitator tank may separate oil from the plant matter by use of solvent where the mixture of solvent and plant oil drains to the boiler tank. The boiler tank comprise of a tank stack (condenser) used for separating extracted plant oil from the solvent by boiling off the solvent and a vacuum chamber used to extract residual solvent from the oil.

The present disclosure provides for improved oilseed extraction methods using sequential extractions with polar solvents and non-polar solvents or extractions with an azeotrope of a polar solvent and a non-polar solvent to produce oilseed meal concentrates having increased protein content and reduced soluble carbohydrate and anti-nutritional compound content.

A carbon dioxide extraction system which recirculates CO.sub.2 and/or other gases in a continuous loop for maximum extraction efficiency and which recovers substantially all gases at the end of the extraction cycle for cost savings and greater workplace safety. The extractor utilizes a dual pumping system which can incorporate high vapor pressure CO.sub.2 and/or lower vapor pressure gases such as propane, butane, chemical refrigerants such as R134a, and other lower vapor pressure gases. The system allows the operators to work with supercritical CO.sub.2 alone with high pressure liquid pump(s), lower vapor pressure gases alone with modified refrigerant recovery pump(s), or a mixture of CO.sub.2 and lower vapor pressure gases using a combination of high pressure liquid pump(s) for extraction and modified refrigerant recovery pump(s) for full recovery of gases at the end of an extraction cycle.
