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. n This is achieved in that soluble constituents are extracted from the starting material in a first extraction step, using CO 2 , and subsequently, in a second extraction step, other constituents are extracted with compressed hydrocarbons. |
