SOLVENT EXTRACTION PROCESS

摘要

A process for extracting a compound or composition of matter from a raw material containing that compound or composition as a constituent part is described. The process comprises the steps of (1) contacting the raw material with an extraction solvent comprising a pentafluoropropane so as to extract the compound or composition from the raw material into the solvent, and (2) separating the solvent containing the extracted compound or composition from the raw material. The process is particularly adapted for extracting flavours and fragrances from materials of plant origin.
