Abstract
The method of producing a lipid composition comprises an extraction treatment step to extract a lipid comprised in a hydrated raw material by using an extraction solvent comprising a polar solvent and a nonpolar solvent, and a separation treatment step to separate an extract solution obtained in the extraction treatment step into a polar solvent phase comprising a first lipid fraction and a nonpolar solvent phase comprising a second lipid fraction.

A method of producing a lipid composition, the method comprising:
- an extraction treatment step to extract a lipid comprised in a hydrated raw material by using an extraction solvent comprising a polar solvent and a nonpolar solvent;
- and
- a separation treatment step to separate an extract solution obtained in the extraction treatment step into a polar solvent phase comprising a first lipid fraction and a nonpolar solvent phase comprising a second lipid fraction.
An apparatus for producing a lipid composition, the apparatus comprising:
- an extraction treatment component for extracting a lipid comprised in a hydrated raw material by using an extraction solvent comprising a polar solvent and a nonpolar solvent;
- and
- a separation treatment component for separating an extract obtained in the extraction treatment component into a polar solvent phase comprising a first lipid fraction, a nonpolar solvent phase comprising a second lipid fraction, and a solid fraction phase.
A lipid composition, wherein the EPA to DHA mass ratio (EPA/DHA) in the fatty acids constituting the lipid is 1.2 to 7.2, the proportion of phospholipid in the total lipid is no lower than 3% by mass and no higher than 54% by mass, the cadmium concentration is 0.4 mg or lower per kilogram of lipid, the arsenic concentration is 3 mg or lower per kilogram of lipid, and the concentration of dioxins is 2 pg-TEQ or lower per gram of lipid.
