| Abstract: | With the aim of optimization of ultrahigh pressure extraction of soybean lecithin, quadratic rotating design was employed to investigate the influence of four factors including pressure, time, concentration of ethanol, ratio of solvent to raw material, and to establish a regression model. The obtained optimum extraction parameters were pressure 280 MPa, time 5 min, concentration of ethanol 85 %, ratio of solvent to raw material 45 mL/g, the yield of soybean lecithin was 10.51 mg/g. |
