Abstract

In order to fractionate or/and refine natural lipid materials by extraction with compressed gases, the natural materials are used in a liquid form and they are extracted with a liquid mixture of 50 to 90% by weight propane and 10 to 50% by weight carbon dioxide which is in a subcritical state.
