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
At higher temperatures above 180Â°F (82Â°C), however, changes to MPC properties will be more noticeable. There are two ways in which heat can affect MPC: 1  Denaturation of the whey proteins present in the MPC.2  Accelerating calcium-casein reactions.xcess heat exposure can cause: 1  Decrease of protein solubility. 2  Decrease in emulsion stabilizing. 3  Change in organoleptic properties in food and beverage applicationsâtexture and flavor.
