The destabilization of milk proteins, primarily casein, resulting in their coagulation and the formation of solid clumps is a phenomenon observed when milk is subjected to elevated temperatures. This process is often visually apparent as a separation of the milk into solid curds and liquid whey. For instance, heating milk to near boiling point, especially when acidic ingredients are present, can rapidly induce this separation.
Understanding this protein destabilization is critical in various culinary applications and dairy processing techniques. Historically, controlled destabilization has been a fundamental step in cheesemaking, allowing for the concentration of milk solids and the development of diverse flavors and textures. The ability to predict and control this process impacts the quality and consistency of dairy products.
