Abstract:
A method for extracting total lipid fractions from marine and aquatic animal material, said method comprising the steps of:(a) placing marine and aquatic animal material in a ketone solvent to achieve extraction of the soluble lipid fraction from said marine and aquatic animal material; (b) separating the liquid and solid contents; (c) recovering a first total lipid rich fraction from the liquid contents of b) by evaporation of the solvent present in the liquid contents; (d) placing said solid contents in an organic solvent selected from the group of solvents consisting of alcohol and esters of acetic acid to achieve extraction of the remaining soluble total lipid fraction from said marine and aquatic animal material; (e) separating the liquid and solid contents; (f) recovering a second total lipid rich fraction by evaporation of the solvent from the liquid contents of e); and (g) recovering the solid contents.
