Summary : Supercritical fluids, mainly carbon dioxide CO2 under pressure (100-400 bar) and near room temperature (30-60°C), behave as non polar highly selective solvents that are finding an increasing number of applications in the domain of oils and fats : Extraction from solid raw materials (seeds, various vegetal stuffs, etc.) by batch processes whose relatively high costs refrain applications except for high added-value products dedicated to pharmaceutical, cosmetic or diet uses. Fractionation of liquid feeds (oils, molten fats, etc.) by continuous processes in order to obtain refined oils (color and odor removal), or highly purified products (polyunsaturated fatty acids, polar lipids, etc.) for use in pharmaceutical, cosmetic or diet applications. Manufacture of fine powders or more complex structures, such as liposomes or microspheres/microcapsules, especially attractive for designing new drug delivery systems. |
Keywords : supercritical fluids, extraction, fractionation, carbon dioxide, glycerides, oils and fats. |
