title: Supercritical carbon dioxide extraction of the Oak Silkworm (Antheraea pernyi) Pupal Oil: process optimization and composition determination.
abstract: Supercritical carbon dioxide (SC-CO(2)) extraction of oil from oak silkworm pupae was performed in the present research. Response surface methodology (RSM) was applied to optimize the parameters of SC-CO(2) extraction, including extraction pressure, temperature, time and CO(2) flow rate on the yield of oak silkworm pupal oil (OSPO). The optimal extraction condition for oil yield within the experimental range of the variables researched was at 28.03 MPa, 1.83 h, 35.31 °C and 20.26 L/h as flow rate of CO(2). Under this condition, the oil yield was predicted to be 26.18%. The oak silkworm pupal oil contains eight fatty acids, and is rich in unsaturated fatty acids and α-linolenic acid (ALA), accounting for 77.29% and 34.27% in the total oil respectively.
