Description

Technical Field

[0001] The invention relates to the technical field of yak milk powder, in particular to yak milk powder which is helpful in promoting bone growth and development. Background Art

[0002] Yak milk powder is milk powder produced and processed from yak milk. Yak milk has the characteristics of "high concentration, high specific gravity, and high content" and is dubbed "extraordinary nutrition". In terms of unit nutritional content, yak milk is higher than ordinary milk. Children's bones are in the growth stage. At this stage, children mostly consume milk powder to absorb the energy needed for growth, so bone growth and development are closely related to the milk powder consumed.

[0003] Currently available yak milk powder cannot promote bone growth and development, which is mainly due to its nutritional deficiencies. Although yak milk powder is rich in certain nutrients, such as protein and fat, its content of calcium and phosphorus minerals may be lower than other dairy products and cannot effectively meet children's needs for these key nutrients during their growth stage. Summary of the invention
