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 apparatus with method to conduct extractions from plant matter using liquid Butane as solvent and process quantities ranging from an eighth of an ounce to two ounces is disclosed. The apparatus is meant for individual use offering the convenience of size that allows it to be carried in a backpack, a suitcase, a handbag, a purse or a small bag. It is designed to be operated safely almost anywhere by almost anyone following a few simple instructions without requiring to be versed in the art of extractions using liquid Butane in commercial equipment. The risk of fire is minimized to the risk of using a common cigarette lighter due to the small volume of liquid Butane required to operate the extractor.

The present invention describes a method for extraction of a raw material or a combination of raw materials to produce a formulation (NEAT™) rich in phytochemicals and which is based on or rich in oil and proteins, said method comprising—bringing the raw material or combination of raw materials into contact with a solvent being carbon dioxide and which optionally is assisted with one or more co-solvents being GRAS (generally recognized as safe), such as but not limited to water, ethanol, dimethyl carbonate; —performing an extraction in high pressure conditions ranging from subcritical to super critical conditions in carbon dioxide in a pressure range of 250-800 bars and in a temperature range of 15-45° C. to provide a formulation being rich in phytochemicals, e.g. lipids, phenolics, terpenoids and alkaloids and proteins wherein a residue obtained in the method for extraction is subjected to extraction in carbon dioxide at supercritical conditions in a pressure above 72 bars and 31° C., and wherein pressurized hot water is used as a co-solvent or after the extraction with carbon dioxide.

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.

Improvements in extraction techniques are described. The improved extraction is provided by an outlet flow controller nut which enhances the efficiency of the collection of compounds as they are extracted from supercritical CO.sub.2. An improved extraction apparatus which includes precise computer controls based on the properties of supercritical CO.sub.2 is also described. The extraction apparatus enables a human operator to extract compounds from organic material with a minimum of intervention and with greater precision that conventional extraction apparatus, which often requires frequent adjustment and yields imprecise results.

The invention relates to a method for obtaining protein preparations from sunflower and/or canola seeds. At least the following steps are carried out: dehulling sunflower or canola seeds up to a shell content of <5 mass. %; partially deoiling the hulled sunflower or canola seeds in a mechanical manner by means of pressing up to a fat or oil content ranging between >7 and >35 mass. %; and carrying out one or more extraction steps using at least one organic solvent or supercritical CO2.

These steps produce a further deoiling of the sunflower or canola seeds and is carried out after a previous comminution process or during a simultaneous comminution process of the pressed cake to a particle size of <2 mm or a flake thickness of <2 mm as a percolation or immersion extraction. A deoiled protein-containing meal or granulate with good protein digestibility is obtained as a result.

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.

The disclosure provides a method of obtaining an isolated phospholipid enriched krill composition. The method includes a) contacting a crude krill composition with an alcohol in an amount sufficient to provide a phospholipid enriched layer and a non-phospholipid enriched layer; b) forming a phospholipid enriched layer and a non-phospholipid enriched layer, wherein the phospholipid enriched layer is above the non-phospholipid enriched layer; c) isolating the phospholipid enriched layer and the non-phospholipid enriched layer; and d) removing the alcohol from the phospholipid enriched layer to provide an isolated phospholipid enriched krill composition.
