Abstract:
We provide new information on the structural properties of thermal protein hydrogels. It is shown that the pH value during gelation strongly affects the pH-dependent charge and the isoelectric point of the generated hydrogels and thus their pH-dependent swelling behaviour and mesh size. Whey protein hydrogels were thermally generated at various pH values and their swelling kinetics, equilibrium swelling ratio and charge were determined as a function of pH. The apparent mesh size was calculated b...     »
