The formula milk powder for children is an important nutritional supplement food in the dietary structure of children, the height and the weight of children aged 3-15 years are steadily increased, and the brain development enters a second peak period, so that the children aged 3-15 years are in the golden period of the body and intelligence development of the children. During this period, the healthy growth of children requires sufficient energy and various nutrients beneficial to physical and mental development. The formula milk powder for children is a very important nutritional supplement food in the dietary structure of children, and the requirements of body growth and development are met by comprehensively supplementing nutrients through the formula milk powder. At present, the phenomenon of insufficient nutrient content generally exists in the formula milk powder for children on the market, so that the nutrients cannot be well supplemented for children after the children drink the formula milk powder.

In one embodiment of the invention, the children growth formula milk powder comprises the following raw materials in parts by weight:

550 parts of whole milk powder 540-containing material, 160 parts of high-oil desalted whey powder 140-containing material, 130-150 parts of skim milk powder, 20-40 parts of polydextrose, 15-25 parts of lactose, 10-15 parts of calcium carbonate, 2-4 parts of fruit powder, 2-4 parts of vegetable powder, 0.5-1.5 parts of bovine colostrum powder, 120.02-0.05 parts of animal bifidobacterium Bb, 0.3-0.5 part of vitamin C, 0.1-0.3 part of hydrolyzed yolk powder, 0.1-0.15 part of compound vitamin A, 0.02-0.05 part of compound vitamin D, 0.1-0.3 part of colostrum basic protein and 8.55-17.15 parts of nutrition enhancing substance.

Specifically, the children growth formula milk powder provided by the embodiment of the invention takes whole milk powder as a base, and the whey powder mainly comprises whey protein and lactose. The high-oil desalted whey powder is prepared by removing mineral salts from whey powder. For children, high mineral content increases kidney burden, so demineralization is necessary and the protein ratio can be adjusted. The feed also comprises polydextrose, lactose, calcium carbonate, fruit powder, vegetable powder, bovine colostrum powder, bifidobacterium animalis Bb-12 parts, vitamin C, hydrolyzed yolk powder, compound vitamin A, compound vitamin D, colostrum basic protein, nutrient enrichment substances and other components to supplement the content of the nutrient components, thereby better helping children supplement the nutrition required in the growth process.
