A milk powder long height formula containing hydrolyzed whey protein and calcium-phosphorus ratio and a preparation method thereof

By using a milk powder formula with a high ratio of hydrolyzed whey protein to calcium and phosphorus and a dry preparation process, the problems of unreasonable calcium and phosphorus ratios and low digestibility of large-molecule proteins in existing milk powders have been solved. This results in high calcium and phosphorus absorption and utilization, fast protein digestion, strong product compliance, and good stability, making the product suitable for the growth and development needs of children and adolescents.

AI Technical Summary

Technical Problem

The calcium-to-phosphorus ratio in existing milk powder formulas does not meet the physiological needs of bone mineralization, the digestibility and absorption efficiency of large molecule proteins is low, the functional components lack targeted synergistic design, the process and production are disconnected, and the compliance is insufficient, resulting in low nutrient retention and poor product stability.

Method used

The formula uses a milk powder with hydrolyzed whey protein and a calcium-phosphorus ratio, with a precisely designed calcium-phosphorus molar ratio of 1.8-2.0:1. It is combined with microencapsulated milk mineral salts and selects oligopeptide-type hydrolyzed whey protein. The dry preparation process includes stepwise dry powder mixing, nitrogen protection and fine granulation, and strict control of humidity and temperature to ensure uniform mixing and stability of active ingredients.

Benefits of technology

It achieves improved calcium and phosphorus absorption and utilization, faster protein digestion and absorption, significant synergistic effects of functional components, strong product compliance, meets national standards, reduces production costs, is compatible with existing dry production processes, and improves product stability and nutrient retention.
