The invention relates to the technical field of food, and discloses a preparation method for chicken
protein enzymolysis liquid and the prepared chicken
protein enzymolysis liquid. The preparation method for the chicken
protein enzymolysis liquid comprises the following steps of: crushing cleaned fresh chicken pieces, adding water to soak the crushed chicken, regulating the pH value to be between 6.8 and 7.2, adding
protease, performing enzymolysis for 2 to 3 hours at the temperature of between 50 and 55 DEG C, filtering, collecting the filtrate, and thus obtaining the chicken protein enzymolysis liquid, wherein the
mass ratio of the fresh chicken pieces to the
protease is 100:3-100:6, and the
protease consists of composite protease and
flavor protease in a
mass ratio of 1:3. The chicken protein is hydrolyzed by adopting a
biodegradation technology under the combined action of the composite protease and the
flavor protease, so that the
hydrolysis degree of the protein can be improved, the content of
leucine with effect of improving the
flavor is improved, sourness and bitterness of the enzymolysis liquid are weakened, the delicate flavor of the enzymolysis liquid is improved, the
mouthfeel is improved, and the chicken protein enzymolysis liquid has fresh taste and thick fragrance.
