Chapter 23: The Application of Supercritical Carbon Dioxide Extraction of Functional Compounds
Published:16 Dec 2014
The use of sub-critical and supercritical CO2 can selectively extract functional molecules from complex raw materials often avoiding lengthy and costly purification steps. Many of these raw materials are themselves sustainable plant products or waste streams leading to integrated, sustainable and economic manufacturing using CO2 as the process solvent. This chapter examines sustainable sources of CO2, process technology and the application of this technology in the extraction and fractionation of oleochemicals, terpenoids, alkaloids and metals.
