In a method for extracting products of value from animal or vegetable starting material, a solution is to be created, with which extraction is improved, with regard to both the yield and separation of natural products to be extracted, and management of the method. This is achieved in that soluble constituents are extracted from the starting material in a first extraction step, using CO2, and subsequently, in a second extraction step, other constituents are extracted with compressed hydrocarbons. |
