The disclosure discloses a method for preparing functional grease through segmented solid-state fermentation of mixed fungi, and belongs to the field of edible oil processing. According to the disclosure, soybeans are used as a main fermentation substrate, for the requirements for different functional nutrition, the soybeans are matched with other oil seeds, fungus segmented solid-state fermentation is used and combined with a supercritical extraction fractionation technology, so that the purposes of improving the aftertaste of soybean oils and generating different flavors are achieved, and the nutritional value of the grease is improved. The fungus segmented solid-state fermentation of the disclosure can improve the oil yield, improve the fatty acid composition of the grease, and increase the content of main flavor substances such as pyrazines, alcohols and phenols, and the sensory functions such as flavor and color of the grease more meet the requirements of consumers for innovative products. Fermented dregs can be further processed to produce byproducts like functional polypeptides, so that sustainable green development is realized.

An apparatus for the extraction of compounds from botanical material using a condensable gas solvent includes sequential extraction and separation stages.

The present invention relates to a polyunsaturated fatty acid composition comprising Omega-3 fatty acids, 17-HDHA and 18-HEPE. The composition can furthermore comprise DPA and/or an acceptable carrier and can be present in a capsule or other suitable dosage unit. The invention also relates to the process of obtaining the composition and methods for using same.

System and methods are disclosed with a holding tank to receive liquid and cryogenically frozen biomass; a cavitator to generate shock waves and pressure variations, wherein the shock waves and pressure variations are to the biomass and the liquid to separate oil from the biomass; a sensor to determine when oil concentration exceeds a threshold; and a valve to transfer the oil and liquid to an oil tank when the threshold is met.

Some variations provide a system for extracting a product from biomass, comprising: a process chamber having an internal volume; one or more mechanical elements configured to controllably and reversibly mechanically seal the process chamber and reduce the internal volume to mechanically compress the biomass; a fluid port in flow communication with the process chamber; and a collection sub-system in flow communication with the fluid port. Other variations provide a method of extracting a product from biomass, the method comprising: introducing biomass into a process chamber; mechanically sealing the process chamber; mechanically compressing the biomass to release a first fluid material; mechanically decompressing the biomass; introducing an extraction solvent into the process chamber; maintaining process-chamber pressure from about 1 bar to about 1000 bar, wherein the extraction solvent extracts a second fluid material; and recovering the second fluid material from the process chamber. High processing throughput is enabled with this invention.

An improved process for producing refined oils free of contaminating waxes, resins, and lipids from botanical plant matter using an improved in-line winterization process is disclosed. The biomass is fed into an extraction vessel where the oils are extracted using a solvent, followed by a two-stage separation. Both the temperature and pressure of the solvent going into the separators are controlled for effective separation. Additional solvent is added to enhance the separation efficiency between the refined oil and the undesired fraction containing the contaminants. This process provides an alternative to current wax mitigation techniques, such as alcohol based solvent winterization.

A method comprising the stages of: olive input, separation of the stone from the olive skin and pulp, with the removal of the whole stone; electric pulsing of the olive paste generated in the previous stage, process of dehydration of the pulsed olive paste up to a humidity of less than 30% in a continuous vacuum drying machine and subsequent separation of the oil by centrifugation of the olive oil, followed by dehydration of the degreased pulp up to a humidity of less than 10%; and lastly, application of supercritical fluids (CO2 with or without modifier) to the degreased and dehydrated pulp, under agitation, pressure, temperature and time conditions, obtaining olive extracts and olive flour. The generation of waste, consumption of water, use of highly toxic solvents and loss of the sensory quality of the oil is avoided, the yields improved and the necessary times reduced.

The disclosed embodiments include systems and methods for the solvent extraction of a substance from a material. The disclosed systems include multiple tanks and an extraction column in communication with the tanks. Solvent transport is accomplished via pressure differentials that are established between or among tanks to cause the solvent to be transported between or among said tanks.

Described herein are compositions from refined oil from plant matter, and in particular from seed, bean, nut, kernel, or pulp (e.g., wood pulp) material of virgin and/or non-virgin plant matter, and methods of forming those compositions. The methods typically include the steps of (i) at least partially separating the seed, bean, nut, kernel, or pulp material from other portions of the plant matter; (ii) extracting an oil comprising one or more triglycerides from the seed, bean, nut, kernel, or pulp material; (iii) refining the oil to remove one or more impurity components; and (iv) chemically or physically modifying the refined oil.

[Problem] Provision of a method for fractionating lipids using liquefied dimethyl ether as a solvent. [Means for Solving] To provide a method for fractionating a lipid using liquefied dimethyl ether as a solvent.
