[0022] The invention provides a preparation method of donkey-hide gelatin peptide with low pro-inflammatory response, comprising the following steps:
[0023] (1) Superfinely pulverizing donkey-hide gelatin blocks through a 500-mesh sieve to obtain superfine donkey-hide gelatin powder;
[0024] (2) Mix the donkey-hide gelatin superfine powder obtained in step (1) with the non-specific enzyme chain enzyme protease E according to the mass ratio of 2000-2500:1, add 1.5 to 2 times the mass of donkey-hide gelatin superfine powder and dissolve it in warm water at 38°C to 42°C, Enzymatic hydrolysis for 3 to 5 hours to obtain sugar enzymatic hydrolysis glue;
[0025] The non-specific enzyme protease E (Pronase E) releases N-sugar chains and obtains sugar chains at the reducing end while hydrolyzing peptide bonds, improving the antioxidant properties of the final product and reducing inflammatory reactions.
[0026] (3) Adding protease to the enzymatic hydrolyzed gelatin solution obta...

[0032] A preparation method of donkey-hide gelatin peptide with low pro-inflammatory response, comprising the following steps:
[0033] (1) Superfinely pulverizing donkey-hide gelatin blocks through a 500-mesh sieve to obtain superfine donkey-hide gelatin powder;
[0034] (2) Mix the donkey-hide gelatin superfine powder obtained in step (1) with the non-specific enzyme chain enzyme protease E according to the mass ratio of 2000:1, add 1.5 times the mass of donkey-hide gelatin superfine powder in warm water at 40°C to dissolve, and enzymatically hydrolyze for 4 hours. Stir to maintain the temperature, and monitor the pH value so that the pH value is maintained between 7 and 8, and the sugar enzymatic hydrolysis glue is obtained;
[0035] (3) Adding protease to the enzymatic hydrolyzed gelatin solution obtained in step (2) for enzymatic hydrolysis, so that the molecular weight of the hydrolyzed product is between 1000Da and 3000Da, and inactivating the enzyme at high temperature...
