Antihypertensive Peptide Prepared From Freshwater Fish Meat Protein Based On Ethyl Esterification Modification and Preparation Method Therefor

Abstract

The present invention belongs to the technical field of the preparation of antihypertensive active peptides from aquatic products. An antihypertensive peptide prepared from freshwater fish meat protein based on ethyl esterification modification has a structural sequence: Tyr-Leu-Arg-Leu-His-Phe-OEt. A preparation method for the antihypertensive peptide prepared from freshwater fish meat protein based on ethyl esterification modification includes the following specific steps: Step 1: isolating an active peptide from freshwater fish meat protein; and Step 2: performing ethyl esterification modification on the active peptide isolated from the freshwater fish meat protein. The activity and stability effects of the antihypertensive peptide prepared by this method are significantly improved.
