[0048] The embodiment of the present invention discloses a preparation method of bird's nest peptide with simple preparation process and good flavor, which specifically includes the following steps:
[0049] 1) Cleaning: Soak the dried bird’s nest in medical-grade purified water at 50°C-60°C for 30-60 minutes, crush, wash, drain, add 20-60 times the amount of medical-grade purified water and simmer for 30-60 minutes until the bird’s nest is Transparent, soft waxy, no hard core state;
[0050] 2) Refining: pass the stewed bird's nest through a colloid mill for 2 to 3 times, and control the fineness of the bird's nest pulp particles within 10 μm to obtain bird's nest pulp;
[0051] 3) The first biological enzymolysis: Pour the bird’s nest slurry into the enzymolysis tank, add purified water, the ratio of solid to liquid is (1-8): 100, and adjust the pH to 6.0-8.0, start stirring, and the speed is 30-70rpm (Keep the bird's nest pulp in a stirring state), and heat up to the tempe...
Embodiment 1
[0059] A preparation method of bird's nest peptide, comprising the following steps:
[0060] 1) Soak the dried bird’s nest in medical-grade purified water at 50°C for 40 minutes, crush, wash, drain, add 30 times the amount of medical-grade purified water and simmer for 30 minutes until the bird’s nest is transparent, soft and waxy, without hard core;
[0061] 2) passing the stewed bird's nest through a colloid mill twice to control the fineness of the bird's nest pulp particles within 10 μm to obtain bird's nest pulp;
[0062] 3) Pour the bird's nest slurry into the enzymatic hydrolysis tank, add medical-grade purified water to measure the concentration of dry bird's nest to 5%, adjust the pH to 7.5, start stirring at a speed of 40rpm, and heat up to the temperature of the material in the tank to 50°C, then add Neutral protease 0.03%, carry out the first enzymatic hydrolysis, the enzymatic hydrolysis time is 40min, and the temperature of the constant temperature process is con...
Embodiment 2
[0069] A preparation method of bird's nest peptide, comprising the following steps:
[0070] 1) Soak the dried bird’s nest in medical-grade purified water at 60°C for 60 minutes, crush, wash, drain, add 40 times the amount of medical-grade purified water and simmer for 50 minutes until the bird’s nest is transparent, soft and waxy, without hard core;
[0071] 2) Pass the stewed bird's nest through a colloid mill for 3 times, and control the fineness of the bird's nest pulp particles within 10 μm to obtain the bird's nest pulp;
[0072] 3) Pour the bird's nest slurry into the enzymatic hydrolysis tank, add medical-grade purified water to measure the concentration of dry bird's nest to 8%, adjust the pH to 7.0, start stirring at a speed of 50rpm, and heat up to the temperature of the material in the tank to 60°C, then add Neutral protease 0.07%, carry out the first enzymatic hydrolysis, the enzymatic hydrolysis time is 50min, and the temperature of the constant temperature proce...
