| titleOfInvention | Method for extracting soybean lecithin |
| abstract | The invention provides a method for extracting soybean lecithin, and relates to the technical field of phospholipid preparation. The invention uses supercritical CO 2 -ethanol mixed solvent as extractant for supercritical CO treatment of soybean powder 2 And (2) extracting, namely performing high performance liquid chromatography separation on a crude soybean lecithin extract obtained by taking a water-organic solvent as a mobile phase, so as to further improve the purity of the soybean lecithin, wherein the volume fraction of water in the mobile phase is 0-20%, and the organic solvent comprises one or more of a chlorinated hydrocarbon solvent, a lower alcohol and tetrahydrofuran. The invention adopts supercritical CO 2 The soybean lecithin crude extract obtained by extraction has the advantages of high soybean lecithin content, high purity, simple operation, no solvent residue, and environmental protection. The invention adopts high performance liquid chromatography to further improve the purity of the soybean lecithin. The invention adopts supercritical CO 2 The purity of the obtained soybean lecithin is more than 99 percent by using a method of combining extraction and high performance liquid chromatography separation. |
