    摘要： A process for fractionating the constituents of a solution obtained by extracting plant or animal material with an aqueous-organic solvent where the aqueous-organic solvent is a mixture of water and a water-miscible organic solvent, generally including the steps of contacting the solution with a near-critical fluid to produce a raffinate phase containing high polarity constituents and water, and a near-critical fluid phase containing low to medium polarity constituents, separating the near-critical fluid phase from the raffinate phase, and recovering the low to medium polarity constituents from the near-critical fluid phase and the high polarity constituents from the raffinate phase.

    摘要： A process for extracting a wide range of lipophilic compounds from urea-containing solutions is described. The process utilises a near-critical fluid as the extraction solvent. The process is particularly applicable to the extraction of polyunsaturated fatty acids from the filtrate obtained upon urea fractionation, as employed in the processing of fish and other oils. In contrast to known processes, the lipophilic compounds may be extracted without the use of non-food grade solvents, and are suitable for pharmaceutical and cosmetic use.
