Rate of the vegetable oil extraction with supercritical CO sub(2) - III. Extraction from sea buckthorn

Oil from the seed and pulp of sea buckthorn berries (Hippophae rhamnoides L.) was extracted with carbon dioxide at pressures 9.6-27 MPa and temperatures 25-60 degree C. Influence of extraction conditions on solubility and mass transfer rate was studied. No marked changes in composition of extracted...

Summary:Oil from the seed and pulp of sea buckthorn berries (Hippophae rhamnoides L.) was extracted with carbon dioxide at pressures 9.6-27 MPa and temperatures 25-60 degree C. Influence of extraction conditions on solubility and mass transfer rate was studied. No marked changes in composition of extracted oil in the course of extraction were observed. Experimental extraction curves were evaluated using a model with grinding efficiency, volume mass transfer coefficients in solid and fluid phases, and parameter of flow asymmetry as adjustable parameters. The solid-phase mass transfer coefficient was increasing with rising temperature.
