Abstract
The invention relates to a method for preparing a composition that is very rich in squalene produced by fermentation of micro-organisms. The method is characterized in that it comprises a purification step selected from the group including: supercritical CO2 extraction in a multi-stage counter-current fractionation column with extract reflux, and short-path molecular distillation.
