Embodiment 1
[0050] A preparation method of chicken bone collagen protein powder, comprising the following steps:
[0051] ⑵ Micro-crushing: crush the chicken skeleton into a fine sauce with a particle size of 100-150 mesh;
[0052] ⑵Biological enzymatic hydrolysis: put the fine sauce into the reaction kettle, add protease, the amount of protease added is 1 / 1000 of the weight of fine sauce, and carry out enzymatic hydrolysis, the temperature of enzymatic hydrolysis is 50 ℃, and the time of enzymatic hydrolysis is 2 hours;
[0053] (3) Atmospheric pressure cooking and extraction: the product after enzymolysis was heated to 100°C for 2 hours under normal pressure cooking and extraction;
[0054] (4) Separation and concentration: the bone residue and sundries in the feed liquid after atmospheric cooking and extraction are separated, and then concentrated to 30% of Brix to obtain chicken bone concentrate;
[0055] (5) Blending: Take the Maillard reaction concentrate, add the Maillard reactio...
Embodiment 2
[0078] A preparation method of chicken bone collagen protein powder, comprising the following steps:
[0079] ⑴Superfine crushing: crush the chicken skeleton into a fine sauce with a particle size of 100-150 mesh;
[0080] ⑵Biological enzymatic hydrolysis: put the fine sauce into the reaction kettle, add protease, the amount of protease added is 1 / 1000 of the weight of fine sauce, and carry out enzymatic hydrolysis, the temperature of enzymatic hydrolysis is 52 ℃, and the time of enzymatic hydrolysis is 2 hours;
[0081] (3) Atmospheric pressure cooking and extraction: heat the enzymatic hydrolyzed product to 105°C and extract by atmospheric pressure cooking for 2 hours;
[0082] (4) Separation and concentration: the bone residue and sundries in the feed liquid after atmospheric cooking and extraction are separated, and then concentrated to 35% of Brix to obtain chicken bone concentrate;
[0083] (5) Blending: Weigh the Maillard reaction concentrate, add the Maillard reactio...
