Supercritical fluid extractions in biotechnology
Trends in Biotechnology, 1990Over the past decade, supercritical fluid (SCF) extraction has been shown to deserve consideration as an alternative to liquid-liquid extraction or distillation. Most current commercial applications of SCF extraction involve biologically produced materials; the technique may be particularly relevant to extraction of biological compounds in cases where ...

Theoretical models for supercritical fluid extraction
Journal of Chromatography A, 2012For 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/Chromatography
2020The solvating power of supercritical fluids is highly dependent on the density of the fluid. High fluid density in the supercritical fluid is achieved as a result of the high pressures created by the system rather than by intermolecular attraction as with liquids.

Instrumentation for supercritical fluid extraction
1993Sample preparation frequently involves the conversion of a solid sample into a liquid prior to analysis (Majors, 1991a). This can be achieved by using liquid—solid extraction techniques for isolating the analyte from its matrix. Traditionally, Soxhlet extraction can be used effectively for this purpose.

Supercritical Fluid Extraction of Triglycerides
Separation Science and Technology, 1990Abstract The demand for natural products has resulted in considerable interest in supercritical fluid (SCF) technology. The advantages of using SCFs as extraction solvents have been well documented. The ease of solute-solvent separation, low toxicity, and the ability to vary the solvent power make the use of SCFs attractive to the food industry, in ...

Application of Supercritical Fluid Extraction in Biotechnology
Critical Reviews in Biotechnology, 2005In 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

Supercritical fluid extraction instrumentation
1998Since the late 1980s, supercritical fluid extraction (SFE) instrumentation has evolved from a chemical engineering research tool into large-scale commercial applications (e.g. the extraction of caffeine from coffee beans) and finally into the analytical laboratory as an efficient preparation method for a wide range of chemical compounds from a variety ...

ENVIRONMENTAL APPLICATIONS | Supercritical Fluid Extraction
2000Since its development in the late 1980s, supercritical fluid extraction (SFE) has successively faced a growing interest in the early 1990s, then a less attractive period, followed by a renewing interest in SFE in recent years. Indeed, despite some major drawbacks and the concurrence of other extraction techniques, SFE still appears as an ...

Supercritical Fluid Extraction of Carotenoids
2014Carotenoids represent one of the most widespread groups of naturally occurring pigments found in fruits, vegetables, and sea products, and serve as powerful antioxidant and precursors of vitamin A. Carotenoids exhibit yellow, orange, and red colors but when they are bound to proteins, they acquire green, purple, or blue colors.

Extraction and processing with supercritical fluids
Journal of Chemical Technology & Biotechnology, 2008AbstractOVERVIEW: Extraction and processing with supercritical fluids (SCF) is increasingly gaining importance in the food, pharmaceutical and chemical industries. Supercritical fluid extraction (SCFE) using carbon dioxide (CO2) as a solvent has emerged as a highly popular technology today over the conventional techniques for extraction of natural ...
