P. Nautiyal, Auteur ; K. K. Tiwari, Auteur Année de publication : 2011 Article en page(s) : pp. 5723-5726 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Supercritical  state  Carbon  dioxide Résumé : Dill seed oil contains constituents that work as carminative and find extensive use in the pharmaceuticals, food, flavors, cosmetics, and medical industries. The present study was thus carried out to investigate supercritical carbon dioxide (SC-CO2) process technology for the extraction of dill seed oil (Anethum sowa). The effects of pressure, temperature, flow rate, and batch time of SC-CO2 were optimized. The best results for dill oil extraction were obtained at of 35 °C, 25 MPa, and a density of 0.88 g/cm3. The dill oil obtained by SC-CO2 was obtained in good yield and a short batch process time. The major constituents extracted by SC-CO2 were limonene, 27.93%; carvone, 9.76%; dihydrocarvone, 26.74%; and dillapiole, 34.05%. The yield of oil was 5 wt %.
