The invention discloses composite 
protein milk 
powder and a production method thereof, and belongs to the field of foods. The composite 
protein milk 
powder is prepared from the following raw materials: 50 to 70 weight parts of milk 
dry matter, 10 to 20 weight parts of 
soy protein, 10 to 20 weight parts of peanuts, 2 to 5 weight parts of amygdingus comnnis, 0.4 to 0.6 weight part of composite 
protein binding agent, and 8 to 10 weight parts of 
sugar or sweetener, wherein the composite protein binding agent is one of 
sodium tripolyphosphate and 
sodium hexametaphosphate or a compound of which the ratio of the 
sodium tripolyphosphate to the 
sodium hexametaphosphate is 2:3. The production method comprises the following steps of: preparing materials, 
grinding soybeans to obtain soybean milk, 
drying and 
grinding the peanuts and the amygdingus comnnis to obtain 
powder, warming the milk, mixing, homogenizing, sterilizing, concentrating and spray-
drying. The invention has the advantages that: the used raw materials are organically combined and have complementary 
nutrition; and the composite protein milk powder contains an immunoglobulin 
antibody which can strengthen the 
disease resistance of human bodies, has health-care effects of preventing 
cancer, protecting 
skin, beautifying, strengthening bones and teeth, reducing 
cholesterol and the like, has good taste and 
flavor, high reconstituability and a long quality guarantee period, and meets the time requirements of fast pace of work and life and high physical consumption.
