Aspects of the present invention provide methods of drying lecithin in a batch reaction, comprising the steps of obtaining a lecithin-containing material (derived from a crude refining stream) comprising 15-50% water, 10-30% acetone insoluble matter, and 10-20% free fatty acid; adding a fatty acid source (also derived from a crude refining stream) to the lecithin-containing material composition to obtain a lecithin/fatty acid reaction mixture; and blowing dry gas through the gum/fatty acid reaction mixture to obtain a resultant dried lecithin fatty acid blend having a water content of less than 2%. The resultant dried lecithin fatty acid blend may be used in asphalt or oil field applications.

Methods of isolating phenols from phenol-containing media. The methods include combining a phospholipid-containing composition with the phenol-containing medium to generate a combined medium, incubating the combined medium to precipitate phenols in the combined medium and thereby form a phenol precipitate phase and a phenol-depleted phase, and separating the phenol precipitate phase and the phenol-depleted phase. The methods can further include extracting phenols from the separated phenol precipitate phase. The extracting can include mixing the separated phenol precipitate phase with an extraction solvent to solubilize in the extraction solvent at least a portion of the phenols originally present in the phenol precipitate phase.

A liposome composition having a lipid bilayer membrane, made of a crude or de-oiled lecithin, at least one triglyceride, a non-triglyceride active agent, and conditioned water. The liposome composition may be utilized for purposes and treatments including increased plant growth, insecticide or insect repellant, inhibiting fruit decay, forensic labeling of plants, wound treatment, and cosmetic applications.

Phosphatidylserine powder compositions of the present invention were found to provide more homogeneous dispersion and demonstrate reduced sedimentation, compared to conventional phosphatidylserine powders, when mixed without processing by high pressure homogenization in water or other liquids. The composition of the present invention comprises phosphatidylserine and at least 80% (w/w) of the composition has a particle size of 500 microns or less. Nutritional, nutraceutical, or pharmaceutical compositions including the phosphatidylserine powder compositions of the present invention are also provided. Process for preparing phosphatidylserine powder compositions according to the present invention is also provided and includes sieving.

Novel active compositions having antimicrobial and anti-inflammatory activity are described, the activity provided by an active component prepared in a suspension, the active component being at least a single chain fatty acid having a carbon length of 12, or between 12 and no more than 18. The fatty acid may be esterified and/or ethylated or methylated. As an antimicrobial the active component has activity against one or more microorganisms including Staphylococcus spp., Streptococcus spp., Mycobacterium spp., Clostridium spp., and Candida spp., with an MIC as low as 0.0018 μg/ml. As an anti-inflammatory, it is at least as or is more effective than cyclosporine in preventing T-cell proliferation in response to a trigger, such as stimulation by the one or more microorganisms. The active component is more active when combined with a phospholipid (e.g., lecithin, phosphatidylcholine) and caused to form liposomal nanoparticles. It is also more active when caused to form coated liposomal nanoparticles. Compositions with said active components may be provided internally and/or topically on a surface or on skin.

The resultant dried lecithin fatty acid blend may be used in asphalt or oil field applications.

The invention relates to a method for aggregating and separating an organic material mixture which is provided in a dissolved form in an aqueous emulsion. The method is characterized by the following steps: a) providing an aqueous emulsion with organic compounds which are provided in the emulsion in a dissolved form, said organic compounds being carboxylic acids, phospholipids, glycolipids, glyceroglycolipids, phenols, sterols, chlorophyll, and/or sinapines, b) mixing the emulsion from step a) with an aqueous solution containing copper(II) ions and/or calcium ions until an aggregate formation is achieved, and c) separating the aggregates from step b) by means of a sedimentation, filtration, or centrifugation process after achieving an aggregated phase of the organic compounds from step b).

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.
