英文摘要: The main focus of the present study is to produce deoiled palm kernel cake from palm kernel using the supercritical carbon dioxide (SC-CO2) extraction method. Response surface methodology (RSM) was used to optimize the process parameters of SC-CO2 extraction of oil from palm kernels. The influences of pressure, temperature and extraction time on the yield were investigated. Results showed that the experimental data were fitted into the second order polynomial model. The linear terms of SC-CO2 pressure, temperature and extraction time had the significant effect on the yield of the oil extraction from the palm kernel. The optimum SC-CO2 extraction process parameters were pressure 44.6 MPa, temperature 60 °C and extraction time 50 min. Under these experimental conditions, the oil yield was about 49.2%. The presence of nutrient and anti-nutrient compositions in deoiled PKC subjected to SC-CO2 (PKCsc) was also investigated and compared with the nutrient and anti-nutrient compositions of PKC collected from palm oil mill (PKCM). Determination of the nutrient compositions in deoiled PKCsc and PKCM revealed that SC-CO2 maintained the nutrient compositions in deoiled PKCsc during extraction of palm kernel oil. Determination of the anti-nutrients compositions in deoiled PKCsc and PKCM showed that SC-CO2 effectively influenced the anti-nutrients in deoiled PKCsc. The findings of the present study suggest that SC-CO2 extraction is an effective technique to produce deoiled PKCsc, which can be used as a cheap source of protein and fiber for human and animal food consumption. © 2016 Elsevier Ltd.
