Figure 3 Polyphenols’ effect of κ-casein aggregation (A) Time-course of the light scattered intensity from κ-casein (50 μM=1 mg/ml) incubated in absence (black circles) and in presence of 120 μg/ml of apple peel polyphenols (red circles). (B) Time-course of the hydrodynamic diameters of κ-casein (50 μM=1 mg/ml) incubated in absence (black circles) and in presence of 120 μg/ml of apple polyphenols (red circles) obtained from cumulant analysis of intensity autocorrelation function.
