Abstract

See full text

The present disclosure discloses a casein micelle with composition and structural features simulating human milk and a preparation method thereof. The method includes the following steps: adding a citrate ion, a calcium ion, and a phosphate ion to a solution of compound casein to obtain a mixed solution; and then adjusting the pH of the mixed solution to 6.7-7.4, and achieving a constant volume with water to obtain 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. In the solution of the casein micelle simulating human milk, the concentrations of compound casein, citrate ion, calcium ion and phosphate ion were 0.3-0.6%, 1.5-4.2 mM, 4.5-10.8 mM, and 1.1-4.5 mM, respectively. The casein micelle simulating human milk of the present disclosure is similar to human milk casein micelle, and has low allergenicity.
