1. A method for preparing a casein micelle simulating human milk, comprising the following steps:
adding three ions involving a citrate ion, a calcium ion, and a phosphate ion to a solution of compound casein to obtain a mixed solution; and if the pH of the mixed solution is below the range of 6.7-7.4, adjusting the pH of the mixed solution to 6.7-7.4 by adding a NaOH solution or a KOH solution, and obtaining a solution of the casein micelle simulating human milk;
wherein β-casein, κ-casein, and αs1-casein have a mass proportion of 65-71%, 17-23%, and 9-15% in the compound casein respectively; and
in the solution of the casein micelle simulating human milk, the compound casein has a mass concentration of 0.3-0.6%, the citrate ion has a concentration of 1.5-4.2 mM, the calcium ion has a concentration of 4.5-10.8 mM, and the phosphate ion has a concentration of 1.1-4.5 mM.
