Title:
Kinetics of formation and physicochemical charaterization of thermally-induced \textgreekb-lactoglobulin aggregates 
Abstract:
The kinetics of heat denaturation and aggregation for β-lactoglobulin dispersions (5% w/v) were studied at 3 pHs (6, 6.4, and 6.8) and at a heating temperature of 80 ◦C. Protein aggregates were characterized for hydrodynamic diameter, microstructure, and molecular weight by means of dynamic light scattering, transmission electron microscopy, and polyacrylamide gel electrophoresis, respectively. Concentration of native β-lactoglobulin decreased with holding time and with a decrease in the pH. App...    »
