1 Heat 2 cups of water to boiling. 2  In a saucepan, heat the milk just to boiling, and remove from heat. 3  Place tea bags into 2 separate cups. 4  Pour the water into cups, filling â of cup. 5  Let the tea steep (soak) for 5 minutes, then remove bag. 6  Fill the rest of the cup with the hot milk.  Add sugar to taste.
denaturation is a process in which proteins lose their shape and therefore their function because of changes in ph or temperature discuss the process of protein denaturation proteins change their shape when exposed to different ph or temperatures
Besides, for whey proteins, the solubility values were minimum at the pH value of 4.5, which is the isoelectric point of whey proteins, for all temperature values. It was also observed that at pH 4.5, the solubility decreased as the temperature increased, which indicated that the protein denaturation occurred.
