The present invention provides a method for manufacturing the milk 
powder. The method comprises the following steps: (1) pretreating 
raw milk; (2) dissolving ingredients in water, fully stirring them evenly to obtain an ingredient solution; (3) mixing the treated 
raw milk and the ingredient solution uniformly to obtain a 
mixed solution; (4) homogenizing the 
mixed solution, and then conducting sterilization and concentration to obtain concentrated milk; and (5) then adding 
glutamine transaminase accounting for 0.02-0.08% of the 
mass of the concentrated milk, stirring the substances evenly, and keeping reaction, and then performing 
spray drying to obtain milk 
powder. The method provided by the invention uses 
glutamine transaminase to replace a 
thickening agent, and 
protein reacts to generate a grid structure, so that after 
brewing the milk 
powder, the milk liquid has suspension function, the anti-
precipitation effect of the milk liquid obtained by 
brewing of the milk powder can be significantly improved. By adding 
sodium citrate, the stability of concentrated milk can be increased, the action time of 
glutamine transaminase is shortened, and its action effect is increased. The method provided by the invention provides a new solution for 
precipitation prevention of milk powder.
