METHOD FOR EXTRACTING LIPID FROM TISSUE OF MARINE AND AQUATIC ANIMAL

摘要

PROBLEM TO BE SOLVED: To provide a method for extracting a lipid fraction from a raw material derived from marine and aquatic animals.

SOLUTION: This method comprises extracting a first liquid component and a first solid component of a phosphatide-containing lipid fraction from the raw material of the marine and aquatic animals by a ketone solvent, and then subjecting the solid component to solvent extraction using an alcohol or ethyl acetate (preferably ethyl acetate) to extract a residual soluble lipid fraction. The remaining non-soluble particulate component is also recovered since it is enriched in proteins and contains a useful amount of active enzymes.
