Abstract
The invention provides improved processes for extracting and preparing polar lipids (in particular, desirable phospholipids) from krill and other biological sources. The inventors have discovered processes through which it is possible to extract phospholipids to give high phospholipid content and a reduction of undesired components.

A composition comprising a mixture of phospholipid compounds of formula (I):
- wherein:
- R1 and R2 are each independently selected from a fatty acid moiety and —H;
- R1 and R2 include omega-3 fatty acid moieties, such that at least 30% by weight of the phospholipid compounds is composed of omega-3 fatty acid moieties;
- at least 90% by weight of total omega-3 fatty acid moieties are at position R2;
- R1 and R2 are not both —H in a phospholipid compound, and R1 or R2 is —H in less than 3% by weight of the compounds of formula (I);
- R3 is selected from —H, a choline moiety, an ethanolamine moiety, a N-acetylethanolamine, an inositol, and a serine;
- and —R3 is a choline in at least 85% by number of the compounds of formula (I) and wherein the composition has the following properties:
- (a) at least 85% by weight of the composition consists of phospholipid compounds of formula (I), (b) the composition includes less than 300 pg astaxanthins per gram of phospholipid;
- (c) the composition comprises less than 0.01% by weight trimethylamine N-oxide;
- (d) the composition comprises less than 0.01% by weight homarine;
- (e) the composition has less than about 0.03% by weight PUFA (polyunsaturated fatty acid) polymers (f) the composition includes less than 5% by weight sphingomyelin.
