متن کاملGenotoxicity of rice bran oil extracted by supercritical CO2 extraction.
Rice bran oil extracted by supercritical CO2 extraction (RB-SCE) reportedly exhibits pharmacological activities such as antioxidant and in vivo hair growth-inducing effects. Such activities raise the possibility of the development of novel hair growth-inducing agents using RB-SCE. The aim of this study was to investigate the potential genotoxic effects of RB-SCE in three short-term mutagenicity...
متن کاملModelling 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...
متن کاملSeparation of Biomass Pyrolysis Oil by Supercritical CO2 Extraction
Supercritical CO2 extraction was employed to separate simulated and real bio-oils. Effects of extraction pressure, temperature and adsorbents on distribution coefficient (or enrichment coefficient) of five representative compounds were investigated using a simulated bio-oil, which was composed of acetic acid (AC), propanoic acid (PA), furfural (FR), acetylacetone (AA) and 2-methoxyphenol (MP). ...
متن کاملExtraction of oil from wheat germ by supercritical CO2.
This study examined the supercritical fluid extraction of wheat germ oil. The effects of pressure (200-300 bar at 40 degrees C) and extraction time on the oil quality/quantity were studied. A comparison was also made between the relative qualities of material obtained by SFE and by organic solvent extraction. The extracts were analyzed for alpha-tocopherol and polyunsaturated fatty acid content...
