The effect of ethanol addition to supercritical carbon dioxide (SC-CO2), up to 20%, on sunflower seed oil extraction over the range of 150 to 350 bars and 42 to 80鎺矯 was studied. A nonrecirculating home-made bench-scale system was used as extraction equipment. The oil-SC-CO2-ethanol mixture was reduced to atmospheric pressure in a test tube, where two phases, oil and ethanol, were obtained

Safflower seed oil extraction with supercritical CO 2 at series operational parameters of pressure, temperature, flow rate and particle size was investigated in a bench scale apparatus. The results show that the extraction yields plotted as a function of time are significantly affected by the extraction pressure, flow rate and particle size, but extraction yields plotted versus CO 2 used are

The effects of supercritical CO2-extracted sea buckthorn seed oil (SBSO) and pulp oil (SBPO) on microcirculation were investigated using two independent experimental models. In the mouse auricular microcirculation model, topical application of SBSO and SBPO on mouse ear, once or twice per day, for three days increased the count of capillary net

In this research, supercritical CO 2 extraction of chlorogenic acid (CGA) from sunflower seed kernels was investigated by ethanol as co-solvent. The effects of operating conditions including temperature (40閳?0 鎺矯), pressure (10閳?0 MPa), CO 2 flow rate (0.6閳?.8 ml/min) and dynamic extraction time (40閳?20 min) was investigated on the chlorogenic acid (CGA) extraction recovery.

The current research demonstrated antioxidative potential of sea buckthorn seed oil and pulp oil in various models. In our previous research, oral administration of supercritical CO 2-extracted sea buckthorn seed and pulp oils (Aromtech Ltd., Finland) protected stress-, reserpine-, and pylorus ligation-induced gastric ulcer (Xing et al., 2002).

Supercritical fluid extraction (SCFE), based on the utilization of a fluid under supercritical conditions, is a technology suitable for extraction and purification of a variety of compounds, particularly those that have low volatility and/or are susceptible to thermal degradation. The interest in SCFE is promoted by legal limitations of conventional solvents for food and pharmaceutical uses.

CO2-extracts are used as cosmetics ingredients, in perfumes, food and food supplements and in aromatherapy. CO2-extracts are sterile and need no preservation. The highly concentrated supercritical extracts unfold their effects already in low dosages for example as cosmetics ingredients or as bioactive substances in food supplements.
