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.

Claim (Index 1):
A process for preparing a composition which is rich in polar lipids from a biological material containing those lipids, comprising steps of:\n (a) mixing the biological material with a first solvent system in which the polar lipids are soluble, thereby preferentially extracting the polar lipids into a liquid phase of a slurry; (b) washing the biological material with a second solvent system in which the polar lipids are poorly soluble; and (c) mixing the extracted and washed material from steps (a) and (b) with a third solvent system which partitions neutral lipids and polar lipids, wherein steps (a) and (b) can be performed in either order before step (c), and wherein the solvent systems include organic solvent component(s) selected from the group consisting of: water, acetic acid, heptane, acetone, isobutyl acetate, anisole, isopropyl acetate, 1-butanol, methyl acetate, 2-butanol, 3-methyl-1-butanol, butyl acetate, methylethyl ketone, tert-butylmethyl ether, methylisobutyl ketone, cumene, 2-methyl-1-propanol, dimethyl sulfoxide, pentane, ethanol, 1-pentanol, ethyl acetate, 1-propanol, ethyl ether, 2-propanol, ethyl formate, propyl acetate, and formic acid.
