| Abstract: | Technology of ultrahigh pressure extraction for soybean lecithin from soy flakes was developed at normal temperature,the effect of different pressure,time,concentration of ethanol,ratio of solvent to raw material on the yield of soybean lecithin was investigated. It was founded that the obtained optimum extraction parameters were pressure 200 MPa, time 20 min,concentration of ethanol 75%,ratio of solvent to raw material 40 mL/g and the yield of soybean lecithin was 11.33 mg/g. |
