A method for catalyzing the synthesis of phytosterol esters by magnetic immobilized lipase |
| abstract |
The invention provides a method for preparing phytosterol ester by immobilizing lipase with nanocomposite magnetic material. Chitosan with polysaccharide chain structure and rich functional groups is wrapped on the outer surface of magnetic nanomaterial ferric oxide, and then dialdehyde cellulose with excellent flexible structure and biocompatibility is used as macromolecular cross-linking molecule to covalently immobilize the Ionic liquid surfactant-activated lipase. The organic-inorganic magnetic nanocomposite immobilized enzyme prepared by this method has the characteristics of high catalytic activity, convenient separation and good reusability, and can be used to catalyze the esterification reaction of phytosterol and fatty acid to prepare phytosterol ester. The invention provides a green and efficient new method for synthesizing phytosterol ester. |
