Supercritical Carbon Dioxide Extraction of Glycyrrhizin from Licorice Root

As the development of the natural medicine, the glycyrrhizin extracted from the licorice root was found to have potential therapeutic value in the treatment of several diseases, especially available for anti-SARS virus . Therefore, the purpose of this work was to find an optimal method to extract and refine the glycyrrhizin. In this work, the extraction of glycyrrhizin by means of organic solve...

Paprika (Capsicum annuum) oleoresin extraction with supercritical carbon dioxide.

Paprika oleoresin was fractionated by extraction with supercritical carbon dioxide (SCF-CO(2)). Higher extraction volumes, increasing extraction pressures, and similarly, the use of cosolvents such as 1% ethanol or acetone resulted in higher pigment yields. Within the 2000-7000 psi range, total oleoresin yield always approached 100%. Pigments isolated at lower pressures consisted almost exclusi...

Enzymatic Transesterification Coupled to Product Extraction in Supercritical Carbon Dioxide

A mixture of fatty acids ethyl esters (FAEE), rich in short chain fatty acids, was produced and extracted in a combined reaction – extraction system, integrated by the use of supercritical carbon dioxide (scCO2). In this processing unit milk fat was partially converted to FAEE by enzymatic alcoholysis. Simultaneously, the lighter FAEE were extracted from the product mixture by flowing scCO2. Th...

Pond Sludge : Electrokinetics , Carbon Dioxide Extraction , and Supercritical Water Oxidation

At DOE sites, significant amounts of Job Control Waste (JCW) need to be disposed. This JCW is generated and contaminated with polychlorinated biphenyls (PCBs) during clean-up operations. A commercial, plant-based absorbent material, “Toxi-dry”, is used extensively for decontamination and decommissioning of DOE waste sites and is classified a hazardous JCW after use. In this investigation, 1,2,4...
