Abstract:
     The present invention provides a method for preparation of polypeptide and amino acid by using mixed enzyme to hydrolyze the blood obtained from slaughtering animals. Under the conditions of pH value 3-5, and 30-60 deg.C, of temp. it uses papain and/or acid protease to implement hydrolysis and under the conditions of pH 7-9 and 30-60 deg.C, it uses trypsase and/or basic protease to implement hydrolysis. Said invention uses the mixed enzyme stage treatment process, so that the hemalbumin is fully hydrolyzed, and the obtained products are mciromolecular polypeptide and amino aicd. Its hydrolyzates are good in solubility, dispersibility and stability, and their absorptivity is up to 95%.
