Polyacrylamide disk electrophoresis patterns were used to study the effect of 0.10% H2O2 on the interaction between beta -Lactoglobulin and k-casein when heated at 85 degrees C for 30 min. The beta -lactoglobulin was modified by treatment with H2O2 to form an electrophoretic component of reduced mobility that appeared as a diffuse band. There was no observable change in the electrophoretic pattern of the k-casein, although the beta -casein contaminant appeared to have been affected.
