Problems solved by technology

[0002] The liver is the most important metabolic organ in the body, but there are some substances that are toxic to the liver in nature and in the industrial production process of human beings, which are called "hepatotoxicants". The process is directly related to the dose of infection, which can cause different degrees of liver cell necrosis, fatty deformation, liver cirrhosis and liver cancer; liver disease has now become one of the most common diseases in humans and seriously threatens human health; therefore, seeking some Natural product ingredients can effectively protect the liver has become a topic of widespread concern

Abstract

The invention relates to a compound peptide with the liver-protecting effect and a preparation method thereof, and belongs to the field of food processing. The compound peptide is prepared from, by weight, 5-9 parts of a peony peptide, 11-17 parts of a peanut peptide, 15-23 parts of a corn polypeptide, 8-13 parts of a swim bladder polypeptide, 0.5-1 part of herba taraxaci, 1-4 parts of fructus lycii, 3-7 parts of coix seeds and 1-8 parts of xylitol. The preparation method comprises the steps that protein is dissolved and then pre-treated to expose the protease site so that the enzymolysis efficiency can be improved; a multienzyme step-by-step hydrolysis method is used for conducting enzymolysis on the protein so that the polypeptide content in hydrolysis products can be increased and the free amino acid content can be reduced, and after enzymolysis, the peony peptide, peanut peptide, corn polypeptide and swim bladder polypeptide are obtained separately; other ingredients in the formulaare smashed and sieved and mixed with the protein peptides, and the compound peptide is obtained. The obtained compound peptide has the liver-protecting effect.
