Abstract
The adsorption kinetic behaviour of P-lactoglobulin and p-casein solut ions studied by dynamic surface tension measurements was interpreted b y diffusion-controlled models. Approximate solutions of the model led to diffusion coefficients for short and long adsorption times. The coe fficients associated with the short time region were found to be unexp ectedly high. From the long time approximation, the coefficients refle ct a slower process in the adsorption layer which is possibly superimp osed by rearrangement processes.
