Soy phospholipids (SPC) are coproducts of soybean oil processing, and the yield of soybean phospholipids increases with the continuous increase of soybean oil yield. In recent years, new techniques for the isolation and purification of certain phospholipids can greatly improve the development of the medicine (biomembrane bionics, liposomes, intracellular drug carriers, etc.) and chemical ndustries (aggregation and dispersion of nanomaterials, etc.).
