The invention discloses a method for synchronously preparing grease enzymatic deacidification and functional lipid, which comprises the following steps: (1) preparing an enzyme reaction column: filling an immobilized enzyme into the reaction column to obtain the enzyme reaction column; the immobilized enzyme is prepared by immobilizing free lipase to a carrier hydrophobic mesoporous silica; or the immobilized enzyme is a commodity immobilized enzyme; and (2) continuous flow reaction: mixing the high-acid-value oil and an acyl acceptor to prepare a raw material solution, pumping the raw material solution, and carrying out esterification and/or transesterification reaction in the enzyme reaction column to realize deacidification of the high-acid-value oil and preparation of the functional lipid so as to obtain a grease product rich in the functional lipid. The method starts with key technologies such as preparation of immobilized enzyme and construction of an enzyme reaction column, can realize deacidification
