The study of protein interactions has generated great interest in the food industry. Therefore, research on new supramolecular structures shows promise. Supramolecular structures of the whey proteins α-lactalbumin and glycomacropeptide were produced under varying heat treatments (25 to 75 °C) and acidic conditions (pH 3.5to 6.5). Isothermal titration calorimetry experiments showed protein interactions and demon...
