Abstract

A process is disclosed for extracting hydrophobic compounds from substantially fat-, oil-, and wax-free substance mixtures by using at least one non-polar extraction solvent in conjunction with at least one water-soluble organic solvent wherein the extraction solvent containing the hydrophobic compound can be recovered as the upper phase in a phase separation.
