Scientific Explanation of Milk Boiling

To understand why milk behaves the way it does when heated, it's helpful to delve into the science behind it. Milk is a colloidal suspension of fat globules, proteins, and minerals in water. When heated, these components interact in complex ways.

As milk heats, the proteins begin to denature, or change their structure. This process is reversible up to a certain point, but if the milk is heated too quickly or to too high a temperature, the proteins can coagulate and form curds. This is why gradual heating and stirring are so important.

The fat in milk also plays a role in its boiling behavior. Fat has a lower boiling point than water, so as the milk heats, the fat globules can rise to the surface and form a layer. This layer can insulate the milk and prevent it from boiling over, but it can also make the milk more prone to scorching if not stirred.
