Abstract
The present invention provides improved processes for extracting and preparing lipids from biological sources for use in pharmaceuticals, nutraceuticals and functional foods.
Claims55
A process for extracting a polar lipid-rich extract from a biological material comprising:
- contacting said biological material with a concentrated protic solvent under conditions such that polar lipids are preferentially extracted to form a slurry comprising a polar lipid solution and biological residue material;
- separating said polar lipid solution from said biological residue material to provide a separated polar lipid solution;
- adding an aqueous solution to said polar lipid solution to dilute said protic solvent so that said polar lipid solution separates into an upper phase comprising diluted protic solvent and a lower polar lipid-rich bottom phase;
- and
- isolating said polar lipid-rich bottom phase to provide said polar lipid-rich extract.
2 more elements
A phospholipid composition comprising a mixture of phospholipid compounds having the following structure:
- wherein R1 and R2 are selected from the group consisting of a fatty acid moiety and —H and R3 is H or a choline, ethanolamine, inositol or serine moiety, said mixture of phospholipid compounds comprising more than about 85% (mol %) choline moieties at position R3 and more than about 30% w/w omega-3 fatty acid moieties, wherein more than about 90% w/w of said omega-3 fatty acid moieties are at position R2, said composition further characterized in comprising less than about 3% w/w lysophospholipids.
