Extraction of poppy seed oil with supercritical carbon dioxide (SC‐CO 2 ) was performed and the effect of extraction conditions on oil solubility and yield as well as oil composition was evaluated. Within the temperature (50 to 70 °C) and pressure (21 to 55 MPa) ranges studied, 55 MPa/70 °C gave the highest oil solubility (24.1 mg oil/g CO 2 ) and oil yield (38.7 g oil/100g seed). Fatty acid composition of the oil obtained with SC‐CO 2 at 55 MPa/70 °C was similar to that of petroleum ether‐extracted oil ( p > 0.05) with linoleic acid making up 69.0 to 73.7% of fatty acids. Tocol content of the SC‐CO 2 ‐extracted oils varied from 22.37 to 33.35 mg/100 g oil, which was higher than that of petroleum ether‐extracted oil (15.28 mg/100 g oil). Poppy seed oil may have potential in the rapidly growing specialty oil market.
