Preparation method of whole egg powder with milk flavor

The invention belongs to the technical field of food processing, and particularly relates to a preparation method of whole egg powder with milk flavor, which comprises the following steps: selecting fresh eggs, cleaning, shelling to obtain whole egg liquid, and slowly stirring until the whole egg liquid is uniform; adding milk powder into the whole egg liquid, uniformly stirring, adding water to supplement the feed liquid, adjusting the pH value, adding protease, and hydrolyzing; carrying out spray drying to obtain hydrolyzed whole egg powder; and performing Maillard reaction on the hydrolyzed whole egg powder to obtain the whole egg powder with milk flavor. According to the method, whole egg powder and milk powder are used as raw materials, protein is moderately hydrolyzed by adopting an enzymolysis means, meanwhile, the demulsification effect is achieved, and grease is released; then through Maillard reaction, various proteins in the system interact with reducing sugar, and grease in the system is also prop
