Abstract

The invention particularly relates to tuna peptide, an extraction method of the tuna peptide and an application of the tuna peptide as an antihypertensive agent. The tuna peptide is a component with agood health-care effect, and extraction of the tuna peptide from leftovers of tuna processing products is a resource utilization mode with remarkable economic significance. Tuna peptide extracted bya traditional preparation method often has the defects of poor purity, poor sense and the like. The invention provides a treatment method for fermentation and enzymolysis by adopting microorganisms and compound protease at the same time, polypeptide is fully released from leftover protein hydrolysate of tuna production, the extraction efficiency is improved, resin adsorption is combined, and the method has the advantages of no fishy smell, environmental friendliness, a high extraction rate, high purity and the like.

Description

technical field

[0001] The invention belongs to the technical field of protein polypeptide extraction methods, and in particular relates to a tuna peptide, a method for extracting the tuna peptide and its application as an antihypertensive active ingredient in the preparation of antihypertensive preparations. Background technique

[0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0003] The crude protein content of yellowfin tuna back muscle is 26.2%. The fat content is only 0.2%, which is a high-protein, low-fat healthy food; according to the essential amino acid requirement model (adult model) recommended by FAO / WHO in 1973, the back muscle protein of yellowfin tuna is evaluated, and the flavor amino...
