Agglomerated powder SMP 151±3.79e 1.81±0.03df
MPI1/SMP9 136±1.00f 1.82±0.04f
MPI2/SMP8 127±1.73g 1.75±0.02df

Values are the means of three measurements±SD.
MPI (milk protein isolate)/SMP (skim milk powder) mixtures were mixed at different ratios of 1:9 (MPI1/SMP9), 2:8 (MPI2/SMP8), and 3:7 (MPI3/SMP7).
Mean values in the same line with different letters are significantly different (p<0.05).
