| titleOfInvention | A kind of keratic preparation method |
| abstract | The invention discloses a kind of keratic preparation method, comprise the steps: step one, alkaline hydrolysis in the first aqueous solution will be put into containing keratic raw material, and carry out solid-liquid separation and obtain the first keratin solid；Step 2, first keratin solid is put in the second aqueous solution, add appropriate compound protease and carry out enzymolysis 4～5h in temperature 48～52 DEG C, pH8.0～9.0 times, then compound protease is inactivated, subsequently add appropriate keratinase and carry out enzymolysis 2.5～3.5h at temperature 35～40 DEG C, finally carry out solid-liquid separation and obtain the second keratin solid；Step 3, first uses the second keratin solid oxidant to carry out lucifuge oxidation 3.5～4.5h, then carries out solid-liquid separation and obtain the third angle protein solid；Step 4, is dried the third angle protein solid to its water content 5%～less than 8%, and dried the third angle protein solid is the keratin of required preparation. |
