1,1,1,2-tetrafluoroethane: A selective extraction solvent for the generation of novel flavor and fragrance ingredients |
L. M. BUCKALEW, Ineos Fluor Americas, LLC, 300 Dickinson Dr., Ste. 1, Chadds Ford, PA 19317 and S. Corr, Applications Group, Ineos Fluor, Runcorn Technical Centre, The Heath, Runcorn, Cheshire, WA7 4QD, United Kingdom. 1,1,1,2-tetrafluoroethane or HFC-134a, was developed in the late 1980’s as the leading zero ozone depletion potential alternative to R-12 in the refrigeration industry and is now manufactured and used for this purpose on a large scale. Interest in its use as a solvent within the food industry is much more recent and has led to its approval for food use in many countries with the development of a novel licensed processing technology within the last twelve months. This presentation will describe the properties and solvency characteristics of HFC-134a that make it a cost-effective, selective solvent for the extraction of natural products, particularly for the flavor and fragrance industries. This presentation will also describe a pilot-scale facility, based in the UK, for extractions using HFC-134a and illustrate the attractive characteristics of materials processed using HFC-134a.
