Embodiment 1
[0025] An anti-glycation collagen peptide made by the following steps:
[0026] Step S1 Preparation of the total protein crude extract: Weigh the raw material, add sodium hydroxide solution to soak for 2 hours, wash twice, add demineralized water, and homogenize in a grinder to a paste to obtain the total protein crude extract;
[0027] Step S2 Preparation of the crude collagen extract: adjust the pH value of the crude total protein extract to 2, heat to 75° C., and keep the gel for 3 hours to obtain the crude collagen extract;
[0028] Step S3 refining of the crude collagen extract: adding a clarifier to the crude collagen extract, adjusting the pH value to 2, stirring evenly and then standing for 2 hours to obtain a refined collagen product;
[0029] Step S4 preparation of collagen peptide: adjust the pH value of the refined collagen to 5, add complex protease for enzymatic hydrolysis, and enzymatically hydrolyze for 2 hours at a temperature of 45° C. to obtain an enzymatic ...
Embodiment 2
[0032] An anti-glycation collagen peptide made by the following steps:
[0033] Step S1 Preparation of the total protein crude extract: Weigh the raw material and add sodium hydroxide solution to soak for 3 hours, wash 3 times, add demineralized water, and homogenize in a grinder to a paste to obtain the total protein crude extract;
[0034] Step S2 Preparation of the crude collagen extract: adjust the pH value of the crude total protein extract to 3, heat to 80° C., and keep the gel for 5 hours to obtain the crude collagen extract;
[0035] Step S3 refining of the crude collagen extract: adding a clarifying agent to the crude collagen extract, adjusting the pH value to 5, stirring evenly and then standing for 5 hours to obtain a refined collagen product;
[0036] Step S4 preparation of collagen peptide: adjust the pH value of the refined collagen to 7, add complex protease for enzymatic hydrolysis, and enzymatically hydrolyze for 4 hours at a temperature of 50° C. to obtain a...
Embodiment 3
[0039] An anti-glycation collagen peptide made by the following steps:
[0040] Step S1 Preparation of the total protein crude extract: Weigh the raw material, add sodium hydroxide solution to soak for 4 hours, wash 3 times, add demineralized water, homogenize in a grinder to a paste, and obtain the total protein crude extract;
