The invention relates to a method of combined cell digestion and extraction of oil-containing seeds having an oil content of >30% by mass, wherein production of a slurry from the oilseeds and ethanol is followed by a combination cell digestion with a subsequent ethanolic extraction, wherein the smaller portion of the oil of the oilseed and the alcohol-soluble constituents present therein are dissolved in the ethanol in accordance with the dissolution capacity of the ethanol for the oil and the alcohol-soluble constituents, a greater portion of the oil is displaced from the seed cells by the ethanol, forming a free oil phase in the ethanol. The free oil phase is removed and, according to the invention, has semi-raffinate quality, reducing the complexity of refining as an advantage of the method of the invention.

The present invention provides a method for extracting heat-sensitive Antarctic krill oil comprising the following steps. Firstly, frozen Antarctic krill is thawed and minced; a surfactant is added to the minced Antarctic krill to form a supercritical micelle system; extract the Antarctic krill multiple times after pressurizing and liquefying mixed gases; at the same time, a low-carbon alcohol solvent is added to strip the material in the critical micelle; after the extraction is completed, the extractant is removed; the extraction product and the residue after the extraction are subsequently collected; the heat-sensitive Antarctic krill oil can be obtained by high-speed centrifugal separation of the oil-water mixed extraction product. The present method has the advantages of simple operation, low extraction pressure and high safety. The extraction method of gas pressure liquefaction is completed under low temperature sealing conditions.

A method to process microalgae biomass and produce high-value chemicals from microalgae biomass is disclosed. The method uses the same biomass cells to extract more than one component such as are lipids, water-soluble chemicals, carotenoids, polysaccharides and algae meal. The method is a sequence of physical and chemical treatments. Water soluble polysaccharides produced by the method exhibit properties of low viscosity at low shear thinning. A method for extracting dietary fiber from microalgal biomass is disclosed. Compositions of water-soluble polysaccharides that are fermented slowly by colon microbiota with less gas production than commercial dietary fiber FOS are disclosed. The present inventions described herein provide a method of improving colon health by increasing butyrate during a microalgal dietary fiber fermenting process by colonic microbiota.

Present invention relates to a novel process for purification of lipid material for further use as such as e.g. a source of fuel or chemicals.

The invention relates to a process for purification of oil by heat treatment in order to degrade phospholipids present in the non-purified oil.

The present invention provides a process for the enzymatic degumming of unrefined triglyceride oils, said process comprising:

a) providing an unrefined triglyceride oil having a phosphorus content of at least 100 mg per kg of unrefined triglyceride oil;

b) combining the unrefined triglyceride oil with water, lactic acid and enzyme to produce an oil-and-water emulsion, said enzyme being selected from phospholipase, lipid acyltransferase and combinations thereof;

c) keeping the emulsion at a temperature of 20-90 C. for at least 10 minutes; and

d) separating degummed triglyceride oil from the emulsion.

This enzymatic degumming process is extremely effective in removing phospholipids, including non-hydratable phospholipids (NHP), from crude and other unrefined vegetable oils.

A membrane based separation method is for the separation or enrichment of one or more unsaturated compounds from mixtures of chemically similar organic compounds having a different degree of unsaturation, using a membrane, such as an inorganic membrane, functionalized with a metal, such as silver.

An inorganic membrane, preferably modified or grafted with an organic functional group, is further functionalized with a metal, such as silver, for use in the membrane based separation methods.

A process is disclosed for fractionating biomass-based material. The process includes evaporating an evaporable part of biomass-based material in a short path evaporator, SPE, to produce a depitched lights fraction in liquid form, and a heavier pitch fraction. The depitched lights fraction may contain depitched tall oil in liquid form, and the heavier pitch fraction may contain tall oil pitch, TOP.

Provided herein is about refining of vegetable oil. Further provided is the processes in which phospholipids present in the vegetable oil are hydrolysed and the oil is subsequently subject to chemical refining.
