Fractionation of Butter Oil by Supercritical Carbon Dioxide

Vetiver Oil Extraction Optimization Using Supercritical Carbon Dioxide Fluid

Extraction/fractionation and Deacidification of Wheat Germ Oil Using Supercritical Carbon Dioxide

Wheat germ oil was obtained by mechanical pressing using a small-scale screw press and by supercritical extraction in a pilot plant. With this last method, different pressures and temperatures were tested and the tocopherol concentration in the extract was monitored during extraction. Then supercritical extracted oil as well as commercial pressed oil were deacidified in a countercurrent column ...

Fractionation for Biodiesel Purification Using Supercritical Carbon Dioxide

In recent years, biodegradable and alternative biodiesel has attracted increased attention worldwide. Producing biodiesel from biomass involves critical separation and purification technology. Conventional technologies such as gravitational settling, decantation, filtration, water washing, acid washing, organic solvent washing and absorbent applications are inefficient, less cost effective and ...

Lipase Catalyzed Ethanolysis of Fish Oil in Supercritical Carbon Dioxide

Ethanolysis of a mixture of tuna and sardine oil catalysed by lipase Lipozyme 435 (Candida antarctica lipase B) has been studied in supercritical carbon dioxide as reaction medium. The reaction products were analysed by Normal Phase-High Performance Liquid Chromatography (NP-HPLC) and High Temperature Gas Chromatography (HTGC). The reaction has been performed in a stirred tank reactor operating...

Supercritical Carbon Dioxide Extraction of Borage Seed Oil

The oil from the seeds of Borago officinalis L. (borage) is a major commercial source of ?-linolenic acid. The fatty acid has a great potential therapeutic value in the treatment of several diseases. In the present work the efficiency of high pressure extraction of borage seed oil containing ?linolenic acid in high concentrations was investigated. Extraction was performed by semicontinuous flow...
