Embodiment 1
[0028] A processing technology for hydrolyzed fish collagen, comprising the following steps:
[0029] (1) Clean up fish scales and fish skin, drain the water after cleaning, and set aside;
[0030] (2) fish scales and fish skin are soaked in water, and sterilized;
[0031] (3) enzymatically hydrolyzing fish scales and fish skin, and filtering to remove the filter residue to obtain an enzymatic solution;
[0032] (4) passing the enzymatic solution through a molecular weight screening system to obtain a collagen solution graded according to the molecular weight of the collagen;
[0033] (5) Concentrate the collagen solution, dry it, and then process it with a magnetic bar to obtain fish collagen.
Embodiment 2
[0035] A processing technology for hydrolyzed fish collagen, comprising the following steps:
[0036] (1) Clean the fish scales and skins, drain the water after cleaning, and set aside; rinse the fish scales and skins with clean water to remove impurities, and then put them in a basket to drain the water;
[0037] (2) Put fish scales and fish skin into the enzymolysis tank, add water into the enzymolysis tank, the weight ratio of the total weight of the fish scales and fish skin to water is 1:10, and then heat the water to 100°C, And heat and sterilize for 15 minutes;
[0038] (3) Lower the water temperature to 45°C and adjust the pH to 9, then add protease, the amount of protease added is 1000u / g, perform constant temperature enzymolysis for 6 hours, filter and remove the filter residue to obtain the enzymolysis solution;
[0039] (4) passing the enzymatic solution through a molecular weight screening system to obtain a collagen solution graded according to the molecular wei...
