| Popis: | Pecan nut cake (PNC) is residual biomass obtained as a result of cold pressing of pecan oil. PNC oil extractions using compressed carbon dioxide (C−CO2) and compressed liquefied petroleum gas (C-LPG) were performed. The influence of extraction parameters such as pressure (15–25 MPa – C−CO2; 1–2.5 MPa – C-LPG) and temperature (20–60 °C – C−CO2; 20–40 °C – C-LPG) on the extraction yields and chemical profile were determined. The higher yields were achieved at 25 MPa / 20 °C (C−CO2) and 1 MPa / 20 °C (C-LPG). The chemical profile of oils is mainly characterized by fatty acids where the oleic and linoleic acids were the majority compounds found in all samples. Contents of squalene and β-sitosterol also were obtained in the oils. The results showed that PNC is interesting biomass for oil extraction and which separation processes using compressed fluids is an attractive option for processing it. |
