Embodiment 1
[0038] According to the content provided by the present invention, the inventor prepared chicken polypeptide 1, the steps are as follows:
[0039] Step 1, raw material cleaning: first put the chicken breast or chicken skeleton into clean water to clean, remove the sundries;
[0040] Step 2, chopping and mixing: put the cleaned raw materials into a chopping machine and chop them;
[0041] Step 3, emulsification: put the chopped raw materials into a cooker and heat and cook for 1 hour until mature;
[0042] Step 4, controllable enzymolysis: put the above-mentioned mature raw materials into the enzymolysis tank, add the screened endonuclease, and enzymolyze it at a temperature of 40-50°C for 3 hours, wherein the endonuclease includes papaya Protease, alkaline protease; then add exonuclease, enzymolysis time is 3 hours at a temperature of 40-50°C, wherein the exonuclease includes bromelain and flavor protease; after the reaction, heat up to 95-100°C, Inactivate enzyme for 30min;...
