| Abstract: |
| The oil was respectively extracted from hazelnut by cold pressing, organic solvent extraction and supercritical CO2 extraction, and the quality of hazelnut oils and oil extraction rates were compared. Then the supercritical CO2 extraction conditions of hazelnut oil were optimized by single factor experiment and response surface methodology. The results showed that the quality of hazelnut oil extracted by supercritical CO2 was better and the oil extraction rate was higher. The optimal conditions were obtained as follows: extraction pressure 27 MPa, extraction temperature 50?℃ and CO2 flow rate 20 L/h. Under these conditions, the oil extraction rate was 93.32%, and the contents of unsaturated fatty acids was over 95% with oleic acid and linoleic acid as the main fatty acids. |
