Supercritical Fluid Extraction

2022
In the present chapter a wide view of the use of supercritical fluids applied to Natural Product Extraction will be given. Supercritical Fluid Extraction (SFE), especially using CO2, can be a very interesting alternative to classical extraction methods for two main reasons: tunability and sustainability.

Theoretical models for supercritical fluid extraction

Journal of Chromatography A, 2012
For the proper design of supercritical fluid extraction processes, it is essential to have a sound knowledge of the mass transfer mechanism of the extraction process and the appropriate mathematical representation. In this paper, the advances and applications of kinetic models for describing supercritical fluid extraction from various solid matrices ...

Supercritical fluid extraction

Fluid Phase Equilibria, 1986
Abstract Critical fluids find an increasing number of applications in the chemical, food and extractive industries. The main advantages and potential applications of supercritical fluid extraction are reviewed. The selection of supercritical fluid (SCF) solvents is discussed on the basis of their solvency, selectivity and phase equilibrium relations.

Supercritical Fluid Extraction of Grape Glycosides

Journal of Agricultural and Food Chemistry, 2000
Supercritical fluid extraction with methanol-modified CO(2) was used to extract glycosides from grapes. An optimization design involving 12 extraction variables was applied to achieve quantitative recoveries. The most important factor was the amount of organic modifier, a consequence of the high degree of glycoside polarity. By the proposed method, the

Supercritical fluid extraction of mercury species

Talanta, 2003
Supercritical fluid extraction was used to recover organic and inorganic mercury species. Variations in pressure, water, methanol, and chelator create methods that allowed separation of inorganic from organic mercury species. When extracted using a compromised set of extraction conditions, the order of extraction was methyl, phenyl and inorganic ...

Application of Supercritical Fluid Extraction in Biotechnology

Critical Reviews in Biotechnology, 2005
In the present paper recent investigations on the applications of supercritical fluid extraction (SCE) from post fermentation biomass or in situ extraction of inhibitory fermentation products as a promising method for increasing the yield of extraction have been reviewed. Although supercritical CO2 (SC-CO2) is unfriendly, or even toxic, for some living

On-line detection for supercritical-fluid extraction

Journal of Biochemical and Biophysical Methods, 2000
An overview of the direct coupling of supercritical-fluid extraction (SFE) to distinct detection is presented. The versatile construction of this kind of hybrid analytical instrumentation is manifested through the discussion of several interface prototypes, whose characteristics satisfy the requirements of both the SF extractor and detector.
