Extraction kinetics modeling of amaranth seed oil supercritical fluid extraction

supercritical fluid extraction of tobacco seed oil and its comparison with solvent extraction methods

tobacco (nicotiana tabacum l.) is an important industrial crop and its seeds contain significant amounts of oil. the extraction of oil components using solvent at high pressure, or supercritical fluid (scf), has received much attention. in the present study, statistical analyses showed that the average extraction yield of seed oil of five tobacco varieties using sfe was 9.33%, which was higher ...

Vetiver Oil Extraction Optimization Using Supercritical Carbon Dioxide Fluid

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...

Supercritical Fluid Extraction+supercritical Fluid Chromatography

high pressures also requires special equipment. In summary, both RESS crystallization and SAS crystallization appear to be promising methods for generating supersaturation and therefore represent alternatives to conventional crystallization. Such alternatives may prove attractive in applications such as polymer and pharmaceutical processing, or in particle design for drug delivery. It is possib...

Modelling the supercritical CO2 extraction kinetics of soybean oil

Different empirical models were used to describe the supercritical CO2 extraction of soybean oil obtained at series of operational parameters namely pressure, temperature, solvent flow rate and characteristic particle size. Process yields obtained by supercritical CO2 were up to 19.33%. Several kinetic models: Brunner, Kandiah and Spiro, Tan and Liou, Martinez et al. and Esquivel et al. were us...
