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.

The present invention relates to a method of for extracting oil from an oil-containing phospholipid composition, comprising the steps of: (a) Providing the oil-containing phospholipid composition, said composition comprising phospholipids and oil, the oil being in an amount of between and 80 wt % relative to the total weight of the oil composition; (b) Admixing water with the oil-containing phospholipid composition to obtain an aqueous composition, wherein the weight ratio of composition to water is between 6.0:1.0 and 1.3:1.0; (c) Separating the aqueous composition into an oil-rich fraction and an oil-depleted fraction, the oil-depleted fraction comprising water and phospholipids; and (d) removing the separated oil-rich fraction to obtain an aqueous, oil-depleted fraction comprising phospholipids; (e) optionally drying the aqueous, oil-depleted fraction to obtain a dried oil-depleted fraction comprising phospholipids.

Phospholipid concentration methods involve use of a dairy composition, such as buttermilk or butter serum, as a starting material. The dairy composition is subjected to a first ultrafiltration, yielding a first permeate and a first retentate. The first retentate is treated with carbon dioxide and subjected to microfiltration, yielding a second permeate and a second retentate. The second retentate is treated with carbon dioxide and subjected to a second ultrafiltration, yielding a third permeate and a third retentate. The third retentate includes at least 30 wt % phospholipids.

A hydrated lecithin carrier vesicle composition includes a lecithin-derived membrane-forming lipid vesicle in conditioned water for incorporation of an active ingredient to form a dispersed composition. A method of making the hydrated lecithin carrier vesicle includes using lecithin having not more than about 80% w/w phosphatidylcholine in the presence of conditioned water.

Disclosed is a method for making a shelf-stable organic compound in a more water-soluble form, the higher-solubility form being provided in liquid and/or powder. The method utilizes a surfactant solution comprising lecithin, water, and at least one polysaccharide into which at least one limited-solubility organic compound is admixed to form a dispersion.
