THE STUDY OF GRAPE SEED OIL OBTAINED BY EXTRACTION BY SUPERCRITICAL CARBON DIOXIDE

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...

Study of the stability of two different fish oils obtained by extraction with supercritical carbon dioxide

During the last years the evidence of the nutritional benefits of polyunsaturated fatty acids (PUFA), especially omega-3 fatty acids, in the human body has become established. Moreover, the nutrition experts have recently recommended to increase the PUFA consumption in order to maintain an omega-6/omega-3 ratio between 5:1 and 10:1 in the diet [1]. Fish is the major dietary source of ω-3 PUFA; ...

Vetiver Oil Extraction Optimization Using Supercritical Carbon Dioxide Fluid

Grape Seed Oil: Supercritical Extraction, Chemical Analysis and Fractionation

Grape seed oil is a product resulting from the processing of grape marc. It is ever more appealing for the cosmetic and pharmaceutical industries: the pharmaceutical activities concern its antioxidant properties, due to the large content of unsaturated fatty acids. Grape seed oil could be extracted mechanically by pressing or chemically by means of solvents. Among the latter, supercritical CO2 ...

Modeling of the Extraction Process of Tea Seed Oil with Supercritical Carbon Dioxide

The kinetics of the extraction of tea seed oil with supercritical CO2 was studied. A kinetic model of the extraction of tea seed oil using supercritical CO2 was developed on the basis of the differential mass balance to simulate the extraction process. The model could simulate the distribution of the solute concentration in CO2 inside the extraction bed as a function of extraction time and heig...
