Removal of soy protein-bound phospholipids by a combination of sonication, β-cyclodextrin, and phospholipase A2 treatments

► A method to remove residual phospholipids in soy protein has been developed. ► It involves sonication- phospholipase A2-β-cyclodextrin treatment. ► >97% of residual phospholipids and free fatty acids in SPI are removed. ► The method is simple and scalable. ► The method may eliminate generation of beany off-flavour during storage.
