These two solvents are conveniently selected because both are classified as GRAS (generally recognized as safe). Therefore, the green concept of supercritical technology is perfectly maintained. The cosolvent takes the form of a compressed liquid (see Fig. 3) when held in the usual operational conditions of the SFE process. 3 The Solid Matrix In natural sources, the soluble portion of the solid matrix is generally composed of several different classes of organic compounds. P. A. Meireles flavonoids, alkaloids, and many other compounds .

Substitutes to n-hexane for extraction are thus wanted, and terpenes are often put forward for this application. In particular, Tanzi et al.  have shown that terpenes could be efficiently used for the recovery of triglycerides from the algae Chlorella vulgaris. This substitution solution can be investigated using the COSMO-RS and Hansen approaches. 1 Positioning of n-Hexane in the COSMO-RS Panorama As already mentioned previously for chlorinated solvents, looking for solvents having the closest -potentials is a way to identify potential substitutes.
