What happens when you heat milk too much?
Milk is a mixture (called an emulsion) of butterfat, proteins, and water. When milk is boiled, the three components of the emulsion break apart: the milk proteins coagulate and separate from the water, producing what is commonly known as curdled milk. This is how cheese is made.

What happens when milk curdles?
This is what happens when milk curdles. When pH levels drop in milk, it turns acidic and milk protein (casein and others) molecules attract one another to form “curdles” or lumps. These lumps then float on the surface of the solution. The lumps are formed faster at warmer temperatures.
Can you use curdled milk in cooking?
Yes, you can use sour milk for baking. While you may not want to drink a glass of spoiled milk straight up, baking is a great way to use the stuff.

How do you know if boiled milk is bad?
Throw out lumpy or gooey milk.
If the milk becomes lumpy or gooey after being heated, that’s a sign that it’s gone bad. Milk curdles because the high acidity in the soured milk causes proteins in the milk to bond together, creating lumps. It’s normal for the milk to have a thin skin on top when heated.

The biggest reason to heat milk to almost boiling before fermenting is that it improves the texture of the yogurt. During fermentation the bacteria consume lactose and produce lactic acid which causes the milk proteins to denature and coagulate trapping most of the fat.
What causes milk to foam?
When we foam milk, we are forcing water vapour and air into milk while heating it. The proteins create spheres around the air and stabilise into bubbles. The protein chains in milk are polar: one end is hydrophilic (attracted to water), and the other is hydrophobic (repelled by water).
