ABSTRACT:

In order to extent the rheological behaviour of protein-surfactant systems, the viscometric studies on gliadin with sodium dodecyl sulphate (SDS) and cetyl pyridinium bromide (CPB) were made and the effect of pH and temperature on viscosity behaviours were studied. Studies show a minimum point, which corresponds to the isoelectric pH (5.20) of these solutions, has been explained to be due to the contacted state of the molecule caused by the attractive forces between the balanced positive and negative charges on the protein molecule. On either side of isoelectric point, the viscosity depends on factors such as hydrodynamic volume, net charge on the molecule, existence of free ions in the solutions. It has been shown that the interaction of protein molecule with cationic and anionic surfactants depends on the pH-values of protein-surfactant system.
