Method for producing casein phosphopeptide from qula

The invention discloses a method for producing casein phosphopeptide from qula. The method comprises the process steps of: A, adding qula into a dissolving cylinder for dissolving, heating to 40-60 DEG C, controlling the PH at 8-10, and removing fat and impurities at 40-50 DEG C; B, stirring a defatted qula solution in a reaction cylinder with a stirrer at the rotating speed 30-50 revolutions perminute, adding trypsin which accounts for 5 percent of the weight of added qula while stirring, adjusting the pH to 7.5-8.5 with a 0.3-0.7 mol/l sodium hydroxide solution while adding, hydrolyzing for 1.5-2.5 hours, heating to 70-100 DEG C, preserving heat for 30 minutes and eliminating enzyme activity; C, cooling an enzyme hydrolysis solution to 30-50 DEG C, stirring with the stirring machine at the rotating speed 30-50 revolutions per minute, adding active carbon powder which accounts for 2-5 percent of the weight of added qula, stirring for 40-80 minutes, adjusting the pH value to 4.2-5.0 and filtering with a kiese
