Fragrance Extraction A process for extracting fragrant, flavoursome or pharmacologically active components from natural materials using non-chlorinated hydrocarbon solvents. The process enables the more volatile components of plant derived materials, which are frequently lost in conventional methods of extraction, to be extracted. This results in the extracted components bearing a greater similarity to, and possessing a larger number of the characteristics of the original material than conventionally obtained extracts.
