  • Patent number: 8617396
    Abstract: The development and application of a novel non-polar oil recovery process utilizing a non-dispersive solvent extraction method to coalesce and recover oil from a bio-cellular aqueous slurry is described herein. The process could apply to recovery of algal oil from a lysed or non-lysed algae slurry, recovery of Omega fatty acids from a bio-cellular aqueous feed, recovery of Beta-carotene from a bio-cellular aqueous feed and for the removal from produced water in oil production and similar type applications. The technique of the present invention utilizes a microporous hollow fiber (MHF) membrane contactor. The non-polar oil recovery process described herein can be coupled to a collecting fluid (a non-polar solvent such as heptane, a biodiesel mixture or the previously extracted oil) that is circulated through the hollow fiber membrane. In cases where the biodiesel mixture or the previously extracted oil is used the solvent recovery step (e.g. distillation) can be eliminated.

  • Publication number: 20120269951
    Abstract: The present invention is based on the finding that stearin fats, obtainable by dry or solvent fractionation of sunflower high-stearic and high-oleic oils, optionally with seeding with tempered stearin crystals, have a high solid fat content at temperatures higher than 30° C., even higher than cocoa butter or other high saturated tropical fats with a similar disaturated triacylglycerol content due to the presence of disaturated triacylgiycerols rich in stearic acid, and improved melting point due to the presence of arachidic and behenic acids in these disaturated triacylgiycerols, being at the same time healthier that actual fats made from palm, palm kernel and coconut oils, or hydrogenated and trasesterified vegetable oils.

  • Publication number: 20120209018
    Abstract: A method for extracting an unsaponifiable fraction from a renewable raw material selected among oilfruits, oleaginous seeds, oleoproteaginous seeds, seed husks, oil-yielding almonds, sprouts, stones and cuticles of fruits, high-fat raw materials from animals, algae, fungus or yeast, includes the following steps: a) dehydrating and packaging the renewable raw material, not resulting in any extraction of the fat; b) reactive crushing of the fatty packaged raw material in the presence of a light alcohol and a catalyst; c) evaporating the light alcohol; d) concentrating the liquid phase such as to obtain a concentrate including the unsaponifiable fraction diluted in fatty acid alkyl esters; e) saponifying the unsaponifiable concentrate; f) extracting the unsaponifiable fraction from the saponified mixture. The use of an unsaponifiable fraction or co-products obtained by implementing the method for preparing a composition such as a cosmetic, drug, food, or food additive or supplement is also described.

  • Patent number: 8242296
    Abstract: A method of making biofuels and valuable food and neutraceutical products includes dewatering intact algal cells to make an algal biomass, extracting neutral lipids along with carotenoids and chlorophylls from the algal biomass, and separating the carotenoids and chlorophylls. The remaining neutral lipids are esterified with a catalyst in the presence of an alcohol. The method also includes separating a water soluble fraction comprising glycerin from a water insoluble fraction comprising fuel esters and distilling the fuel esters under vacuum to obtain a C16 or shorter fuel esters fraction, a C16 or longer fuel ester fraction, and a residue comprising omega-3 fatty acids esters and remaining carotenoids. The method further includes hydrogenating and deoxygenating at least one of (i) the C16 or shorter fuel esters to obtain a jet fuel blend stock and (ii) the C16 or longer fuel esters to obtain a diesel blend stock.

  • Publication number: 20120122164
    Abstract: The present invention provides methods of processing a biomass, e.g., for producing lipid and non-lipid materials, by inducing autolysis of a biomass. The biomass may be generated using any species of microorganism and any available biodegradable substrate, including waste materials. The lipid and non-lipid materials are present in two separate layers of the autolysate, and they can be used to generate valuable products such as biofuels and nutritional supplements. The present invention further provides a processing apparatus useful for practicing the methods of the present invention.

  • Patent number: 8173826
    Abstract: In some embodiments, the present invention relates to an enrichment process that involves a separation and/or fractionation and/or enrichment of monounsaturated fatty acid/ester molecules from polyunsaturated fatty acid/ester molecules or, correspondingly, monounsaturated molecules from saturated molecules. Such processes are at least partially based on ?(pi)-complexation between metal ions and unsaturated bonds of the extractible molecules (fatty acids/esters), wherein a greater degree of unsaturation provides for greater coordinating (bond) strength and corresponding selectivity in the associated ?-complexation with metal ions.

  • Publication number: 20120059180
    Abstract: A process for purifying a lipid composition having predominantly neutral lipid components having at least one long chain polyunsaturated fatty acid is disclosed. The process employs contacting the lipid composition with a polar solvent, such as acetone, wherein the solvent is selected such that contaminants are less soluble in the solvent than is the long chain polyunsaturated fatty acid. The process is typically conducted at cooler temperatures, including about 0° C. Upon precipitation of the contaminants from the lipid composition, a separation is conducted to remove the precipitated material from the lipid composition. The long chain polyunsaturated fatty acids can include ARA, DPA, EPA, and/or DHA. The process of the present invention effectively winterizes lipid compositions, thereby reducing the tendency of such compositions to become hazy.
