The invention provides a method of immobilising lipase on asymmetric microporous polysulfone polymer membrane by ultrafiltration membrane process to prepare biocatalytic membrane to fabricate a membrane bioreactor for the modification of composition of oils and fats. The hydrolytic activity of immobilized lipase as determined by hydrolyzing olive oil in ultrafiltration cell at 30oC, at 15 psi pressure, at pH 7 is -35.15 U/mg of lipase in comparison to 33 U/mg of native lipase.
