Abstract

Process for simultaneous distillation and extraction of volatile substances from an aqueous medium into a water- immiscible solvent, especially for extraction of volatile aroma components under controlled conditions, wherein the solvent and the aqueous medium are distilled separately from separate receptacles and condensed separately; the condensates are contacted in an extraction cell and the impoverished aqueous phase is separated from the solvent phase which is enriched with the extracted substances by decantation at a location separate from the extraction cell. Also claimed is an apparatus for carrying out the process.
