| 20120083616 | METHOD FOR PRODUCING A CONCENTRATE OF EICOSAPENTAENOIC AND DOCOSAHEXAENOIC ACID ESTERS - The current invention describes processes for obtaining of concentrates of esters of eicosapentaenoic acid and docosahexaenoic acid for their use in massive and regular human consumption either as a pharmaceutical ingredient or as a food ingredient, which are characterized by having neutral and stable organoleptic properties, free of side effects, which are typical from marine oils derivatives, and with low content of Persistent Organic Pollutants (POP). | 04-05-2012 |
| 20130102802 | Method of Lipid Extraction - A method of extracting lipids from wet algae, the method includes hydrolyzing a slurry comprising algae and water by adding an acidic hydrolyzing agent to yield an acidic slurry, hydrolyzing the acidic slurry by adding a basic hydrolyzing agent to yield a basic slurry, separating a liquid phase from biomass in the basic slurry, forming a precipitate within the liquid phase, and separating free fatty acids from the precipitated solid phase with the advantage of removed or reduced chlorophyll contamination of the algal lipids. | 04-25-2013 |
| 20130217904 | METHOD OF EXTRACTING POLAR LIPIDS AND NEUTRAL LIPIDS WITH TWO SOLVENTS - A method for separating polar lipids and neutral lipids from plant material, in particular, intact algal cells, using an amphipathic solvent set and a hydrophobic solvent set. Some embodiments include dewatering intact algal cells and then extracting polar lipids and neutral lipids from the algal cells. The methods provide for single and multistep extraction processes which allow for efficient separation of algal polar lipids and neutral lipids from a wet algal biomass while avoiding emulsification of extraction mixtures. These polar lipids are high value products which can be used as surfactants, detergents, and food additives. These neutral lipids are also high value products which can be used to generate renewable fuels. | 08-22-2013 |
| 20130274490 | Extraction of Lipids From Algae - Various embodiments of the present invention are directed to processes and methods for extracting lipids from a variety of algae species. An exemplary method comprises treating the algae with a mixture of at least one nonpolar solvent and at least one polar solvent heated to temperature at which the nonpolar solvent and the polar solvent are miscible. | 10-17-2013 |
| 20140171670 | Methods And Systems For Bio-Oil Recovery And Separation Aids Therefor - A method and system for bio-oil recovery from biomass are provided which includes adding at least one separation aid to stillage that contains oil to form a treated stillage prior to centrifuging the stillage, and centrifuging the treated stillage in at least one centrifuge to separate at least a portion of the oil from the treated stillage. The separation aid can contain at least one lecithin and at least one oil and optionally at least one surfactant having an HLB value of at least 6. Treated stillage products are also provided which can contain the indicated separation aid and recovered oil. | 06-19-2014 |
