Model whey protein-dominant infant milk formula systems were prepared.
The formulas had different 伪-lactalbumin:尾-lactoglobulin ratios.
Increased 伪-lactalbumin level improved resistance to heat-induced coagulation.
Protein-protein interactions were reduced in higher 伪-lactalbumin formulas.
Viscosity post-heating was lowest in higher 伪-lactalbumin formulas.
