Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A lipid composition, wherein the EPA to DHA mass ratio (EPA/DHA) in fatty acids constituting the lipid is (EPA/DHA)=1.2 to (EPA/DHA)=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. 2. The lipid composition according to claim 1 , wherein the EPA to DHA mass ratio (EPA/DHA) in fatty acids constituting the lipid is (EPA/DHA)=3.4 to (EPA/DHA)=7.2, and the proportion of phospholipid in the total lipid is no lower than 18% by mass and no higher than 39% by mass.
