INFLUENCE OF SOLID-SURFACE ENERGY ON PROTEIN ADSORPTION

Surface energy characteristics of a solid surface influence the extent and rate of protein adsorption, However, critical surface tension det ermined by contact angle measurements, cannot be used to predict the e xtent or rare of milk whey protein fouling onto a particular surface, Radioisotopic iodination of alpha-la and beta-lg was used to show that protein adsorption onto a surface is dependent on protein concentrati on and temperature. Multilayer adsorption was observed with a single p rotein solution and with sequential exposure to the two whey proteins.
