Abstract
The aim of this research was to determine the effect of particle size on dog rose seed oil recovered by the method of Supercritical Fluid Extraction (SFE). Supercritical extraction implemented using dog rose seed particles (d1 < 0.27 mm; 0.27 < d2 < 0.7 mm; 0.7 mm < d3 < 1.4 mm) at 30 MPa, 50 °C, 0.228 L/min flow rate of supercritical carbon dioxide and at the 40 °C separation temperature. The experiments were carried out over the period of 120 min. The results showed that maximum oil obtained at smallest particle sizes (maximal absolute yield-7.63 g from 78.2 g seed). The highest volume of the residue in oil was with particles d1 < 0.27 mm. The GC analyses revealed the oil from dog rose seeds was rich of unsaturated fatty acids.
